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.

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.
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.
Where can companies or home users get the most suitable broadband goods? It is suggested to search on the Internet. Many online stores and companies can give you the right offer. FiberStore as a lead fiber solution supplier, can offer not only fiber optics, but also converters and transceivers. Welcome to our website and custom fiber optic cables which meet your own requirements.
