Protection signaling module (GI-ST plug or SM/DSF-LC plug)
1.
The protection signaling communication module is to communicate with the remote IED for
relay applications. A fiber optical cable classified in the GI optical fiber is mainly used in short
haul communication (shorter than 2km). In medium haul, an optical fiber in SM is required.
In long haul, an optical fiber in DSF is required.
100Base-TX/1000Base-T module (RJ-45 plug)
2.
A twisted-pair cable is required for the LAN connection. The module is used for the GR-TIEMS
operation or the LAN communication. Use a shielded twisted pair cable so that electric
magnetic compatibility is satisfied .

100Base-FX module (SC plug)
3.
A fiber optic cable is required for the connection. 100Base-FX module is used for the LAN
communication. Dual slots space (i.e., labeled with "C11" and "C12") is occupied when a single
(Port A) module is mounted (see Figure 5.3-6; i.e., space "C12" is not blank). Therefore, the
total number for communication ports needs to be cared.
