Industrial Communication Guide

Connectors Fiber optic lines use one conductor per transmission direction (simplex). For this reason, two lines are combined to form a pair so as to be able to transmit and receive data (one line for each direction results in duplex). As such, the connectors normally have a facility for combining two individual connectors to form a pair. The most common connector is the LC connector (Lampert con- nector). Due to its small size, this has replaced the SC connector (Subscriber connector).

As is the case with copper cables, there are also defined categories for fiber optics (defined in ISO/IEC 11801-1). Here the properties of GOF are subdivided into the classes OM1 to OM5 for multi-mode, while OS1 and OS2 apply to single-mode. As with copper-based cables, a higher number means more rigorous requirements, which in turn indicates that higher data rates and distances are possible.
