2-3 Optical Ring System (GI Cable) Wiring
This section describes how to wire the communications cables to a GI cable
Ring System Controller Link Support Board (3G8F7-CLK52-E).
2-3-1 Communications Cables
The following devices are required for the Optical Ring (GI) Controller Link Net-
work.
Use Optical Fiber Cables (Graded Index: GI) with the following optical specifica-
tions.
