Cabling system mostly uses the multimode fibers due to the small number of cables in the trunk line connecting the floors of the building, but in the horizontal direction, there is not a suitable medium that not only can provide sufficient bandwidth, but also is easy to install, low cost, strong anti-interference and so on. The new full-fiber optical network with plastic optical fiber (POF) as the transmission medium, has all the above advantages. The diameter of the plastic fiber is generally 0.3 to 3 mm which is suitable for connection, and light coupling efficiency is higher relatively, and also the plastic optical fiber features lots of benefits like it’s soft, anti-bending, vibration resistance, anti-radiation, low-cost, easy construction. Instead of the traditional quartz fiber and copper cable, the plastic fiber is very suitable for the local area networks with many connection points.

There are two kinds of products needed for structuring large-scale LAN with the plastic optical fibers; they are passive cabling connection products and active plastic optical network devices. 

The plastic optical fiber cabling products include the following parts: POF plastic horizontal fiber optic cable for the horizontal subsystems of integrated cabling, used to achieve the connection between the terminal of each work area and the equipment in the floor communications room; plastic fiber plug is the connector for connecting the plastic optical cable with equipment; plastic fiber jumpers are used for the cross connections between the ODF and the device, or the connection between the fiber optic socket of the work area and the device; The plastic fiber identified the fiber jumpers, which makes it easier to find out each fiber jumper with end-to-end connection from a large number of fiber jumpers in the ODF, thus to reduce the maintenance workload. Plastic optical fiber socket is the system work area information export of plastic optical fiber cabling; plastic fiber coupler is used to connect the connectors of two fibers; plastic fiber distribution frame is a fiber optic termination device for accomplishing the cross-connection and management between fiber and fiber, fiber and equipment.

Plastic optical fiber local area network (LAN) 

Plastic optical fiber network products in the local area network are mainly to achieve the high-speed network connection between the workgroup switches and computer equipment, the main plastic optical fiber network equipment as follows.

The plastic optical fiber sector switches can provide multiple Ethernet fiber ports, and support high-bandwidth, high-performance fiber connections between workgroups or inside workgroups. 

Plastic fiber optic card, the computer PCI card with Ethernet plastic fiber interface, in line with IEEE standards, plug and play, supports full-duplex mode. 

The POF-RJ45 fiber optic transceiver, is a converter from Ethernet fiber port to RJ45, transform the Ethernet electrical signals into optical signals that can be transmitted over the plastic optical fibers, and vice versa.
