SSR-GSX31-02
The SSR-GSX31-02 line card uses SC-style Media Interface Connectors (MICs) to attach to
multimode fiber (MMF) cables.
To attach the segment cables to your SSR-GSX31-02 line card, obtain an MMF cable with an SC
MIC and plug the MIC into the port connector. When you plug the other end of the cable into
another device, ensure that the cable connected to the transmit port on the X-Pedition is connected
to the receive port on the other device. The receive port on the X-Pedition should be connected to
the transmit port on the other device.
