the other end to the Rx port of the peer device.

If the LED is on, the optical fiber link is present.

If the LED is off, no link is present. This might be because the TX and Rx port of the optical fiber
are not connected correctly. In this case, connect the optical fiber again.
Connecting an E1/T1 cable
CAUTION:
When connecting the interface cable, pay attention to the mark on the interface to avoid wrong insertion,
which might damage the interface module or even the router.
H3C recommends that you install a lightning protector at the input end of the 8T1 cables to protect them
against lightning strikes more efficiently when they are led outdoors.
