Conference System
6.25 PRS-FINNA Fiber Interface
Optical network
The fiber interfaces connects a POF to a GOF. Use a GOF to connect two pieces of equipment
in the optical network that are more than 50 m apart and less than 1,500 m. Use the fiber
interfaces as a pair. The first connects a POF to a GOF, the second connects the GOF to a
POF.

Notice!
If the distance between two devices is less than 100 m, a network splitter can be used in the
middle to remove the use of fiber interfaces. Use only the trunk sockets of the network
splitter in this case.
The GOF socket is a double SC socket that uses invisible infra-red light (1300 nm).
