Interface Optical Fiber The FIC-1CPOS can only be connected with an optical fiber cable with an LC-type fiber-optic connector.

Figure 271 LC-type fiber-optic connector

n Fiber-optic connectors: according to ITU, are passive components used to stably but not permanently connect two or more optical fibers. They are indispensable to a fiber-optic communications system in the sense that it allows add/drop connections between optical channels.

Many types of fiber-optic connectors are available, such as:

FC: round fiber-optic connector with screw thread

ST: round plug-in fiber-optic connector
