What is SFP+ Direct Attach Copper Cable?

SFP+ direct attach copper cable, also known as Twinax Cable, is a SFP+ cable assembly used in rack connections between servers and switches. It consists of a high speed copper cable and two copper SFP+ modules. The Plus SFP module allow hardware manufactures to achieve high port density, configurability and utilization at a very low cost and reduced power budget.

Direct Attach Cable assemblies are a high speed, cost-effective alternative to fiber optic cables in 10Gb Ethernet, 8Gb Fibre Channel and InfiniBand applications. They are suitable for short distances, making them ideal for highly cost-effective networking connectivity within a rack and between adjacent racks. They enable hardware OEMs and data center operators to achieve high port density and configurability at a low cost and reduced power requirement.

FiberStore SFP+ copper cable assemblies meet the industry MSA for signal integrity performance. The cables are hot-removable and hot-insertable: You can remove and replace them without powering off the switch or disrupting switch functions. A cable comprises a low-voltage cable assembly that connects directly into two SFP+ ports, one at each end of the cable. The cables use high-performance integrated duplex serial data links for bidirectional communication and are designed for data rates of up to 10 Gbps. Similar to the fiber patch cables, the SFP+ direct attach cables are made up of a cable and two connectors, with the difference that connectors are the SFP+ transceivers instead.

Types of SFP+ Direct Attach Copper Cables
SFP+ Copper Cable assemblies generally have two types which are Passive and Active versions.

1. SFP+ Passive Copper Cable
SFP+ passive copper cable assemblies offer high-speed connectivity between active equipment with SFP+ ports. The passive assemblies are compatible with hubs, switches, routers, servers, and network interface cards (NICs) from leading electronics manufacturers like Cisco, Juniper, etc..

2. SFP+ Active Copper Cable
SFP+ active copper cable assemblies contain low power circuitry in the connector to boost the signal and are driven from the port without additional power requirements.

Optical Transceiver Module Tutorial From FiberStore

What is an Optical Transceiver module?

Optical Transceiver is a computer chip that uses fiber optic technology to communicate between other devices. This is opposed to a chip that transfers information electrically through metal wires and circuits or by the process of using various wave forms to communicate data. An optical transceiver chip is an integrated circuit (IC) that transmits and receives data using optical fiber rather than electrical wire.
Optical transceivers are typically used to create high bandwidth links between network switches. With the optical transceiver you can also create data transmission links capable of long range transmission.

Development of Optical Transceiver Modules

Optical transceivers play an important role in conveying information across communication channels for Ethernet systems. They act as the all-in-one objects that receive and convey inforamtion, similar to those found in radios and telephone systems. With an optical transceiver, networks save much more space and avoid the need of having a transmitter and receiver apart inside a network. Capable of transmitting information further and faster than older models, the newer transceivers continue to change the way transceivers are used and appear, making for smaller, more compact modules than before. Here is a simple development of the transceivers.

Earliest Modules
SFP Module is one of the earliest transceiver devices which were created for Gigabit Ethernet networks and were preferred for their hot-swappable abilities. GBIC, or Gigabit interface Converters, allowed networks the ability to transmit data across copper or fiber-optic channels, creating a more versatile device than transmitters and receivers. Of course, GBIC modules were also have defect, and many had size and compatibility issues that limited their ability to transmit data across particular distances and at certain wavelengths.

XENPAK Modules
XENPAK became the new standard transceiver with increased support across longer distances and for multiple wavelengths. Unlike GBIC transceivers that sent information across either copper or fiber optic channels, XENPAKs included support for both networks, creating a better, more flexible module. And unlike the bigger GBIC transceivers, XENPAKs were capable of conveying data across short and long distances due to their configuration settings located inside the devices. When utilizing a single-mode configuration, networks create a single ray of light to send data across a long distance, while they use a multimode setup to transmit information across short distances. Both single and multimode fiber optics were utilized by networks, creating the XENPAK device ideal.

10 Gigabit Ethernet
X2 Transceiver and XPAK that the older XENPAK modules could no longer keep up with, were made when the 10 Gigabit Ethernet standard took hold. The smaller, more flexible X2 and XPAK standards allowed for even more support for the different Ethernet standards and were capable of transmitting data across longer distances.

And when the 10G SFP (SFP Plus or SFP+) came into existence, the competing standards of X2 and XPAK couldn't continue to control the market as they once had any more. SFP+ modules allowed for more configuration standards for networks, providing various wavelength and distance configurations for Ethernet.


Principle of Optical Transceiver Modules
Optical transceiver generally includes both a transmitter and a receiver in a single module. The transmitter and receiver are arranged in parallel so that they can operate independently of each other. Both the receiver and the transmitter have their own circuitry so that they can handle transmissions in both directions. The transmitter takes an electrical input and converts it to an optical output from a laser diode or LED. The light from the transmitter is coupled into the fiber with a connector and is transmitted through the fiber optic cable plant. The light from the end of the fiber is coupled to a receiver where a detector converts the light into an electrical signal which is then conditioned properly for use by the receiving equipment.

In a word, the optical transceiver module is the role of the photoelectric conversion. The transmitter converts electrical signals into light signals, and through the fiber optic transmission, the receiving end of the optical signals are converted into electric signals.


How Optical Transceivers Work In Personal Computers
When there is an issue, the pieces that make up the personal computers could be a mystery for many people. Without having an established understanding, we can feel helpless and incapable of fixing even the most basic of problems on ourself. So, it's necessary to make clear that how the transceivers work in the computers.
Considering that many of us are constantly on the internet, it may be easy to get an understanding of the most basic optical transceivers and how they make it so you can connect an search the internet with ease. To provide you with a straight connection to the web, you are either connected through a wireless network, or to an Ethernet cable which is connected to your modem or router when you are online. The Cat5 cable as it is also known, plugs into the computer by using the optical transceiver, which is often not housed on the side of your laptop, or the reverse end of the CPU.

There are many various modules that can be utilized as your optical transceiver. Unlike XFP modules, Cisco SFP modules, GigaBit interface converters, or GBIC modules, are some of your more average transceivers, and are input/output modules with one end that plugs into a gigabit ethernet port, while the opposing side is plugged into the fiber patch cables and links the fiber optic networks. Allowing the devices to process the data accordingly, the base function of the GBIC module is to communicate the signals between the Ethernet network and fiber optic network. One terrific aspect of the GBIC module is that it's a hot pluggable, allotting for a port to be changed from one kind of external interface to another by simply plugging the module in to an alternate external interface without having to power down the host switch or router in the process.


Application of Optical Transceiver Modules

Optical transceiver, essentially just completed the converted of data between different media, can realize the connection between two switches or computers in the 0-120km distance. Its main function is to achieve the conversion between optical-electrical and electrical-optical, including optical power control, modulation transmission, signal detection, IV conversion and limiting amplifier decision regeneration. In addition, there are security information query, TX-disable and other functions. Here is a summary in the practical application.

1. Optical transceivers can realize the interconnection between switches.

2. Optical transceivers can realize the interconnection between the switch and the computer.

3. Optical transceivers can realize the interconnection between computers.

4. Optical transceivers can act as the transmission repeater.
When the actual transfer distance exceeds the nominal transmission distance of the transceiver, in particular, the actual transfer distance exceeds 120km alerts, with 2 sets transceiver back to back in the case of on-site conditions allow, repeaters or the use of "optical-optical" conversiona relay, is a very cost-effective solution.

5. Optical transceivers can offer conversion between single-mode and multimode fiber connection.
When the networks appear to need a single multimode fiber connection, you can use a multimode transceiver and a single-mode transceiver back-to-back connections, which can solve the problem of single multimode fiber converted.

6. Optical transceivers can offer WDM transmission.
The lack of resources of long-distance fiber optic cable, in order to improve the utilization rate of the fiber optic cable, and reduce the cost, transceiver and wavelength division multiplexer (WDM multiplexer) with the use of two-way information on the same fiber transmission.


Classification of Optical Transceiver Modules
Optical Transceiver modules can be classified according to the following aspects.

1. Optical Fiber Type
Single-mode fiber transceiver and Multimode fiber transceiver. The single-mode version has a transmission distance of 20 to 120 km, while the multimode one's is 2 to 5 km. Due to the different transmission distance, the transceivers' transmit power, receiver sensitivity and the use of wavelength will be different.

2. Optical Fiber Count
Simplex fiber transceiver and Duplex fiber transceiver. The simplex version receives the data sent in a single fiber transmission, While the duplex one receives data transmitted on a dual fiber transmission. By definition, single fiber devices can save half of the fiber, a fiber that is in the receive and transmit data, where the fiber is very applicable to resource constraints. These products use the wavelength division multiplexing techniques, mostly using the wavelength 1310nm and 1550nm.

3. Transmission Rate
Transmission rate refers to the number of gigabits transmitted per second, per unit of Mbps or Gbps. Optical modules cover the following main rate: low rates, Fast, Gigabit, 1.25G, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G and 40G.

4. Package

What You Should Think About Before Selecting Fiber Cables

Sorting through cables and connectivity options could be a frustrating exercise. It's hard enough working through the categories and levels of copper networking cables, where most cables end with similar connector. What happens when you start looking at fiber cables? This is where things can definitely get confusing! This article tells you how to select the right kind of fiber cables.

Let's move on off by saying that fiber optic cables can be used in a huge variety of applications, from small office LANs, to data centers, to inter-continental communication links. The information lines that connect between North America and Europe, for example, are constructed with fiber optic cable strung underneath the ocean. Our discussion in this article will focus mainly on the kinds of cables present in those small-scale networks closer to home, and in particular to pre-terminated cables which may be designed for installation, called "patch cords", "pre-terms", or any other similar nicknames like fiber patch cables. Prior to you buying, you should make clear the following parameters.

Multimode and Single mode
One of the first things to determine when selecting fiber optic cables is the "mode" of fiber that you'll require. The mode of a fiber cable describes how light beams travel within the fiber cables themselves. It's important because the two modes aren't compatible with each other, which means that you can't substitute one for that other.

There's really not much variety with single mode patch cords, but there's for multimode. You will find varieties described as OM1, OM2, OM3 and OM4 (OM means the "optical mode"). Basically, these varieties have different capabilities around speed, bandwidth, and distance, and the right type to make use of will be based mostly upon the hardware that is being used with them, and any other fiber the patch cords will be connecting to.

Fiber Optic Cable Jackets
Pre-term fiber can be used in a variety of installation environments, and as a result, may need different jacket materials. The standard jacket type is called OFNR, which means "Optical Fiber Non-conductive Riser". This can be a long-winded way of saying, there's no metal in it, so it won't conduct stray electrical current, and it can be installed in a riser application (going in one floor up to the next, for instance). Patch cords are also available with OFNP, or plenum jackets, which are ideal for use in plenum environments for example drop-ceilings or raised floors. Many data centers and server rooms have requirements for plenum-rated cables, and also the local fire codes will invariably have the final say in what jacket type is required. The ultimate choice for jacket type is LSZH, which means "Low Smoke Zero Halogen", that is a jacket produced from special compounds that provide off very little smoke with no toxic halogenic compounds when burned. Again, seek advice from the neighborhood fire code authority to be certain of the requirements from the installation before making the jacket selection.

Simplex and Duplex
Simplex and duplex have only the difference between one fiber or two, and between one connector at each end of the cable, or two connectors each and every end. Duplex patch cords are the most common type, because the method in which most fiber electronics work is they need two fibers to speak. One is used to transmit data signals, and the other receives them. However, sometimes, just one fiber is required, so simplex patch cords may be essential for certain applications. If you aren't sure, you can always be on the safe side by ordering duplex patch cords, and just one of these two fibers.

Fiber Optic Cable Connectors
Remember what we should said at first about copper category cables? No matter what level of twisted pair you were coping with (Cat 5, 5e, etc), you always knew you would be dealing with an 8-position modular RJ-45 plug around the end from the cable. Well, with fiber patch cords, there is a few possibilities when it comes to connectors. The common connector types are FC, LC, SC, ST and MTRJ etc..

These are the most typical selections that you will find when choosing amongst patch cords. If you're able to determine which of these characteristics you need, it is highly likely you will make the right choice when custom fiber optic cables with suitable parameters.

Developing Miniature Fiber Optic Cable Has Become The Trend

In recent years, the industry has been focusing on reducing the footprint of fiber optic network. It can be said that about in 2005, with the development of small bending radius (RBR) fiber by fiber optic suppliers, the trend toward development of smaller cable and hardware had begun to appear. Soon after this new optical waveguide design appeared, people developed international standards, the ie ITU G657, to regulate it. Subsequently, the optical fiber's tolerance to the macrobend and microbend is gradually increased, these fibers which can be "tied knot" begin to allow achieving a smaller size the cable design.

Small Bend Radius Fiber Has High Efficiency

Macrobend is a simple phenomenon easy to understand. For macrobend's performance, ITU G657 stipulates the special optical loss specification at special bend radius. However, some parlances consider the main features that the improved macrobend's performance comes from the small bend radius can achieve smaller size and higher performance cabling. A method for the actual analysis of the differences between the macrobend and microbend is to make a single fiber convolving on your finger to measure macrobend fiber loss, meanwhile put a piece of sandpaper on the fiber and measure the corresponding microbend loss, and then compare the differences between the two.

In the both cases, the underlying optical phenomenons which cause signal loss have a very big difference. When the fiber optic cable is exposed to low temperatures, its material will tend to shrink, and a force is applied along the length along the fiber, which can cause microbend in the fiber optic cable. For example, the improvement of fiber optic cable's microbendtolerance can undoubtedly help to withstand large temperature variations.

Global fiber optic cable manufacturers are utilizing the feature of optical fiber's small bending radius. Their desire is to develope the method that using the fiber optic cable as same as using copper cable - rugged, small size, practical, anyone can easily operate, and will not damage the optical fiber. To achieve this goal, they have also made innovation to the material that used in the fiber optic cables' manufacturing process. Small bend radius fiber bending performance has been enhanced to promote the new materials and manufacturing techniques used in the manufacture of fiber optic cable, which makes the fiber optic cable having the smaller size and lighter weight. Until these problems were solved together, the new generation cable of smaller in size, greater flexibility could be produced.

A major factor in the small radius of the fiber optic cable is the plugged wire and other direct connection cable. Except the obvious benefit of installing more fiber optic cables in the same space, smaller cable size can also speed up the flow of air, because the cables occupy fewer duct space. With active electronic component suppliers trying the miniaturization of electronic enclosures, the importance of this advantage will become more apparent. In such electronic cabinets, heat gradually become an important issue. Typically, one would consider the airflow along the copper (copper itself generates heat), but with the equipment cabinet becoming smaller and hotter, various aspects of the airflow become very important.


Smaller Direct Connection Fiber Optic Cables And Fiber Patch Cables Have Emerged

Smaller size, that's beyond imagination. This phenomenon might not be so obvious now, but as the diameter of the round cable is reduced by one unit, the space occupied by the cable (the circular area) would be reduced much more accordingly. Therefore, the cable diameter is slightly reduced could mean greatly reduction of occupied space. Compared the typically 2.0mm cable to 1.2 mm cable, it can be clearly seen that although the cable diameter is reduced less than a half, the number of cables in the same space (1 square inch) can be mounted is almost 3 times as the original.

In the late 10 years of 2000s, Telcordia released revision 2 for widely used GR-409 standard straight cable. The sub-categories called "mini" cable included in Revision 2, allowed lower production strength of the cable in accordance with GR-409 standard. Revision 2 reduced provisions to the tensile strength of the so-called small package installation, allowing the cable to withstand 9 pounds (40N) of installed load, rather than 22 pounds (100N) standard mounting load. At the time, it was widely believed that reducing the intensity of the production of smaller cable size was required. Compared with a rated load of 22 pounds of cable, the  fiber optic cables which rated tensile load of nine pounds require more careful to avoid damaging the cable to installation personnel.

However, at present, the material that some with small bend radius optical fiber based cable actually uses, design, and methodology make the fiber optic cable's size smaller, and  beyond the original 22 pounds tensile load installation which GR-409 requirements. For example, 1.2mm direct connection cable is now available and can support 30 pounds of rated installation load. Compared to the nominal small cable 2.0mm, this means that the new cable diameter of 1.2mm is three times the intensity, and only occupies a third of the space.

So, soon after, data center managers and other staff will be able to install fiber optic cables much smaller in size than the previous, while will not passively select GR-409's small package, so as not to reduce the cable strength. Look forward to in the near future, we can see hardware which has more smaller size than ever, so we can achieve higher density and more compact cabling management, while ensuring the reliability of the network.

Broadband Has Become Innovation Strength To Communication Technology

"Global communications network construction is sure developing towards more universal and rapid broadband networks." Senior researcher of World Bank Communications Policy, Natasha said that the future of international communication includes the following four objectives.

• 1. The popularization of broadband policy. By 2015, all countries should have developed national broadband plan or strategy including broadband universal access and service definition.

• 2. Affordable broadband services. By 2015, developing countries could afford the basic level of broadband access services (5% less than the average monthly income) through appropriate regulation and market forces.

• 3. The popularity of home broadband. By 2015, 40 percent of households in developing countries can enjoy Internet services.

• 4. Internet access. By 2015, the rate of global Internet user penetration would reach 60%, 50% in developing countries and 15% in less developed countries.

In Natasha's speech respectively illustrated Indonesia and China broadband plan.

Indonesia's 2013-2017 National Broadband Plan: By the end of 2013, Indonesia's fixed broadband would achieve the coverage of 15% of households (1Mbps), 30% of the building (100Mbps) and 5% of the population; mobile broadband would achieve the coverage of 12% of the population (512kbps ). And by the end of 2017 , the fixed broadband would achieve the coverage of 40% to 75% of households (2Mbps), 50% to 80% of the building (1Gbps) and 25% of the population; while mobile broadband would achieve the coverage of 75% of the population (1Mbps).

China's 2015-2020 National Broadband Plan: By 2015, administrative broadband penetration rate would achieve 95%, urban families would achieve 20Mbps broadband speed, metropolitan families would achieve 100Mbps speed, and rural families would achieve 2Mbps rate. By 2020, a comprehensive broadband network covering urban and rural areas would achieve, urban families would achieve 50Mbps, part of metropolitan families would achieve 1Gbps, and rural families would achieve 4Mbps.

Broadband has become an important innovation strength to communication technology. Based on a variety of innovative, broadband is making faster penetration of information technology, which promotes the upgrading of the entire social productivity and stimulates the sustainable economic development. In response to the financial crisis, the United States, Britain, Germany, France, Portugal, Spain, Ireland and other countries have announced their plans to build a national broadband, and many countries have risen this to the height of its national strategy.

As the broadband construction is becoming global, the fiber optic cables and related assemblies are required with a quite large amount. Choosing high quality and cost-effective fiber optic products has become very important to the countries worldwide. And as communication technologies are improved more and more, many new types of optical products are invented. For example, MTP fiber is a new type of fiber patch cables which is used more and more in today's communication construction.

Performance Of Network Interface Cards

A PCI Network Adapter or NIC Card (also referred to as a Network Interface Controller, Network Adapter, LAN Adapter or LAN card) is how your computer connects to the wired network in your home or office. It is a physical and data link layer device which uses MAC addresses. NIC adapter is plugged inside the computer either in the PCI slot or built-in the motherboard. Without it, there would be no interaction between the cord in the wall and your computer!
The network interface card is installed in an expansion slot of the computer. This card connects the computer to a network, and contains information on the computer’s location and also instructions for sending and receiving data over the network. It adds a serial port to the computer and the port connects directly to a network. NIC converts the computers’ low power signals to high power signals that can be transmitted over the network. NIC’s speed is measured in megabits per second (Mbps).
External LAN cards are larger and are placed in any PCI slot on the motherboard, except the PCI Express slot. Internal LAN cards on the other hand come integrated with your chipset. Internal LAN cards are integrated into the motherboard of your computer and generally provide higher transfer speeds on a network. Internal LAN cards require drivers to function, thus if your internal LAN card stop working for any reason you will first need to reinstall your drivers with a fresh download. If however that still doesn’t fix your problems, you will need to buy an external network interface driver. Make sure to buy a network interface card that offers the same transfer speeds as your internal LAN card.
LAN cards usually support network transfer rates of 10, 100 or 1000, megabits per second. Depending on your requirements and network you should choose a LAN card that will provide the optimal transfer rate for your network.
LAN cards are used mostly in ethernet networks and designate an IP address to your connection. This IP address is what defines your computer’s connection on the Internet or your network. Every NIC has unique MAC address and no two NIC cards from two different vendors can have the same MAC address. NIC has twisted pair, BNC and AUI sockets. The one end of the network cable is used to connect with the NIC and the other end is used to connect with the hub or switch. NIC provides the full-time connectivity for the data transmission. Sometimes computers do not communicate with each other due to the malfunctioning of the NIC.
A twisted pair UTP/STP with RJ45 connector is used to connect the computer with the Hub or Switch. Optic Fiber Cable or Fiber Patch Cable can also be used to connect the computer to the hub or switch. A NIC can be wired or wireless and it has digital circuitry and microprocessor. Before buying and installing a network interface card, make sure that it is compatible with the other network devices. There are different vendors of the NIC such as D-Link, 3Com, Intel, Realtek, Baylan and FiberStore.

Higher Data Throughput From Multimode Fiber Patch Cables

Information available at our fingertips in form of digital data today has swelled up to levels which had never been before. At the same time, real time communication has exponentially increased to extremely high levels. A whole class of applications have emerged that demand for transmission of high-speed data.

Necessity may be the mother of invention – optical fiber networks have been invented and deployed to solve the problem of high volume data exchange. And multimode fiber patch cables have grown to be the very first choice one of the different connectors of the wired carriers with endpoint devices.

What are the speed-hungry and volume-hungry data centric applications that have created this entire demand? Some examples of those applications are the Internet, the local area multi-computer networks, the phone networks and the ATM networks. There are many more applications with intense hunger for fast communication resources. For those practical purposes, these communication channels need a high-speed network that can carry enormous volumes of data with minimal attenuation and extreme accuracy. The modern fiber optic cable technology provides exactly this sort of communication.

The multimode patch cables are used to connect this data transmitted over the network towards the devices that they target to cater. These patches may also be used to connect the two loose ends of two fiber optic cables. The patch cables have to be multimode when the requirement is to support multimode optical fibers.

What is a multimode cable poor fiber optics? A multimode is one in which multiple packets of data can be simultaneously carried across the wire. The result is that the network can carry numerous data packets at a instant of time. The multimode mainline network cables are usually short long since the target with these cables is to support high speed and high power multiuser systems in a localized sense. The patches are compatible with the network cables to enable the machine remain aligned with the network objectives. Consequently the multimode patches support multiple user applications transferring data simultaneously, as well as retain the qualities of standard single mode patches like the high network speed, low network hindrances and occasional external interferences.

It’s also interesting to note that the end point devices these patch cables connect can be heterogeneous in nature. The aperture the end point device requires and types of applications supported may be diverse. There exist several different kinds of multimode fiber patch cables you can use based upon the requirements. And depending upon the exact reason why you have to install the patch on your fiber optic network, you shall need to select your patch and go ahead with the required installation.
