Unterminated optical connectors may emit laser radiation. Do not view beam with

optical instruments.

Note:

invalid signal during installation, no alarms are reported since the receive port at the

opposite end of the span has not transitioned from AUTO to IS, even though the

measured receive power is within acceptable levels.

The failed transmit pluggable transmission module appears as an LOS to the receive

pluggable transmission module causing the port state to remain AUTO.

If the receive pluggable transmission module is receiving a signal within acceptable

levels but does not transition from AUTO to IS, replace the transmit pluggable

transmission module at the opposite end of the span.

When connecting fiber loops between the IN and OUT ports on optical circuit

packs, always connect to the IN port first and then the OUT port. This will

prevent any optical radiation from being present at the fiber end.
