42.3 Installation

Refer to section 41.4 for information about the
installation of the fiber interface. The procedures to
install the network splitter and the fiber interface are the
same.

42.4 External connections

42.4.1 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 (refer to figure 42.2).

Note
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.
