About Fibre Optic Patch Cable
Generally, fibre optic patch cable consists of two parts: the fibre optic cable and the fibre optic connectors. Fibre optic patch cable are named by the cables and the connectors together, for example, a LC to SC 3meters single mode simplex APC types fibre optic patch cable, here the name LC and SC stand for the name of specified fibre optic connector, 3 meters is the whole cable length, single mode refer to the cable type, simplex means this cable is with one single core, APC is the polish type of the fibre optic connectors. Fibre optic patch cables are important components used in the fibre optic communications network.

Single mode and Multimode
Single mode and Multimode refer to the fibre optic cable types. Usually single mode fibre optic cables are used in long distance data transmission, multimode fibre optic cables are used in short distance data transmission. Typical single mode cables are yellow, typical multimode cables are orange; by this way people can easily identify the cable types from the colors.

Simplex and Duplex
Simplex means this fibre optic patch cable is with only one core, at each end of the fibre optic cable there is only one fibre optic connector. Duplex can be regarded as two simplex fibre optic patch cables put side by side. Duplex fibre optic patch cables are usually with clips on the connectors to combine it. The duplex fibre optic patch cables are made joint structure of two simplex cables.

Key Tech Data of Fibre Optic Patch Cable
Insertion loss and return loss are two important data of fibre optic patch cables. Insertion loss is as small as better, return loss as big and better.
