Figure 3–25: DIRECT INPUT AND OUTPUT SINGLE/DUAL CHANNEL COMBINATION CONNECTION
The inter-relay communications modules are available with several interfaces and some are outlined here in more detail.
Those that apply depend on options purchased. The options are outlined in the Inter-Relay Communications section of the
Order Code tables in Chapter 2. All of the fiber modules use ST type connectors.
3.3.2 FIBER: LED AND ELED TRANSMITTERS
The following figure shows the configuration for the 7A, 7B, 7C, 7H, 7I, and 7J fiber-only modules.
