2. Fiber Termination Box

Cable termination box, also known as optical fiber termination box or fiber termination box, is a connection device between several cores cables and termination equipments, mainly used to fix the cable termination, store and protect the remaining fiber optics, the splicing of fiber optic cable and fiber pigtail.
3. Fusion Splicer

Fusion splicer, the connection of two optical fiber cables, should joint the fiber inside the cable, because the fiber is just like glass, must re-fused special joint on the two ends, then the ends melt together, so that the light signal can be passed.
Light transmitting in fiber causes a loss, this loss is mainly composed of transmission loss of optical fiber itself and the splicing loss at optical fiber joints. Upon the order of optical cable, its own fiber optic transmission loss is also basically identified. The fiber joints splicing loss is determined by fiber optic itself and on-site construction. Efforts to reduce the optical fiber joints splice loss, can increase the transmission distance of optical fiber amplifier and improve the attenuation margin of fiber link.
4. Fiber Media Converter
Fiber optic media converter, is an Ethernet transmission media conversion unit to interchange the twisted-pair electrical signal of short distance and light signal of long distance.
Fiber converters are generally used in actual network environment where Ethernet cable can not cover and must use fiber optic to extend the transmission distance, the access layer application and usually located in metropolitan area networks; while it also plays a huge role in helping the fiber at the last kilometer connecting to the metro network and more outer layer network.
5. Fiber Optic Multiplexer
Fiber Optic Multiplexer is a fiber communication equipment to extend data transmission, it is mainly through the signal modulation, photoelectric conversion technology, using the optical transmission characteristics to achieve the purpose of remote transmission. Optical multiplexer generally used in pairs, divided into optical transmitter and optical receiver, optical transmitter completes the electrical/light switching, and optical signal is sent for optical fiber transmission; optical receiver mainly converts the light signals from the fiber receiver back into electrical signals, completing the light/electricity conversion. Optical multiplexer is used for remote data transmission.
Optical multiplexers are divided into many types, such as telephone optical multiplexer, Video Multiplexer, Video Audio Multiplexer, Video Data Multiplexer, video Audio Data Multiplexer and so on. And commonly used is Video Multiplexer (especially widely used in security industry).
Optical multiplexer is the terminal equipment of light signal transmission. Its principle is: a photoelectric conversion transmission equipment; put at both ends of the optical cable; one transmitter and receiver, just as its name implies multiplexer. So optical transmitter and receiver are used in pairs, usually buy optical multiplexer is said to buy a few pairs, instead of several.

Fiber media converters

As a kind of Media Converter, Fiber media converters this known as fiber transceivers or ethernet media converters, are quite obvious networking devices those make it possible for connecting two dissimilar media types such as twisted pair Cat 5 or Cat 6 cable with fiber optic cabling. They may be essential in interconnecting fiber optic cabling-based systems with existing copper-based, structured cabling systems. Fiber ethernet media converters support many different communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, as well as multiple cabling types such as twisted pair, multi-mode and single-mode fiber optics. Fiber media converters can connect different Local area network (LAN) media, modifying duplex and speed settings.
For example, switching media converters can connect legacy 10BASE-T network segments to more modern 100BASE-TX or 100BASE-FX Fast Ethernet infrastructure. For instance, existing Half-Duplex hubs may be attached to 100BASE-TX Fast Ethernet network segments over 100BASE-FX fiber. When expanding the reach with the LAN to span multiple locations, fiber transceivers are useful in connecting multiple LANs to form one large campus area network that spans more than a wide geographic area.

Fiber media converters support a variety of data communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, T1/E1/J1, DS3/E3, as well as multiple cabling types for example coax, twisted pair, multi-mode and single-mode fiber optics. Media Converter types range from small standalone devices and PC card converters to high port-density chassis systems offering many advanced features for network management.

On some devices, Simple Network Management Protocol (SNMP) enables proactive management of link status, monitoring chassis environmental statistics and sending traps to network managers in case of a fiber break or perhaps link loss on the copper port.

Fiber media converters can connect different Local area network (LAN) media, modifying duplex and speed settings. Switching media converters can connect legacy 10BASE-T network segments to more recent 100BASE-TX or 100BASE-FX Fast Ethernet infrastructure. For instance, existing Half-Duplex hubs can be linked to 100BASE-TX Fast Ethernet network segments over 100BASE-FX fiber.

When expanding the reach of the LAN to span multiple locations, media converters are of help in connecting multiple LANs to make one large campus area network that spans more than a limited geographic area. As premises networks are primarily copper-based, media converters can extend the reach from the LAN over single-mode fiber approximately 130 kilometers with 1550 nm optics.

Wavelength-division multiplexing (WDM) technology in the LAN is very beneficial in situations where fiber is at limited supply or expensive for provision. In addition to conventional dual strand fiber converters, with separate receive and transmit ports, there are also single strand fiber converters, which can extend full-duplex data transmission approximately 70 kilometers more than one optical fiber.

Other benefits of media conversion include providing a gentle migration path from copper to fiber. Fiber connections can help to eliminate electromagnetic interference. Also fiber media converters pose being a cheap solution for many who need it switches for use with fiber along with have enough money to pay for them, they can buy ordinary switches and make use of fiber media converters to make use of making use of their fiber network.

As a fiber optic media converter, you can use it anywhere in the network to integrate newer technology with existing equipment to support new applications, technologies and future growth. Fiber Converters are key aspects of Optical Networking because its long distance operation, high bandwidth capacity and reliablity make fiber optics probably the most desired channel for data communications. Instead of costly, across-the-board upgrades, media converters can extend the productive lifetime of the existing cabling along with the active equipment. FiberStore offers a wide variety of professional fiber optic media converters for Fast Ethernet, Gigabit Ethernet, Serial Datacom interfaces and E1 or T1 voice/data communications.
