Cables and connectors
|
- Duplex SC/PC connector (Rx and Tx); single-mode intermediate-reach
fiber
|
|
LEDs
|
One tricolor per port:
- Off—Not enabled
- Green—Online with no alarms or failures
- Amber—Online with alarms for remote failures
- Red—Active with a local alarm; router has detected
a failure
