Alcatel-Lucent 1830 PSS-16 - Aprnode; Aprosc

APRNODE
APRNODE (APR Active - Node)
When an LD is used that contains a high-power optical amplifier (>20 dBm), if there is an
LOS condition within the node that could carry high power from the LD, then the output
power from the LD is reduced to a safe level. The condition will automatically clear up to
100 seconds after the LOS condition within the node has cleared. APRNODE can also
occur briefly after some other APR conditions clear.
After a condition that leads to the complete shutdown has cleared, the amplifier will
return to eye-safe level (≤ 10 dBm), then will go back up to the greater that 10 dBm level
before the failure. The software will check whether all monitored connections are
receiving power. APRNODE will be active during this time. Once the checks have been
completed, APRNODE will clear automatically.

1
Proceed to “LOS” (p. 2-148) to clear the LOS condition.
APROSC
APROSC (APR Limited - OSC SFP failure condition)
The APROSC condition occurs when the SFP on the line-terminating LD is removed, or
if the SFP fails. An LD with a high-power optical amplifier (> 20 dBm) is either at an ILA
or at the egress position at an add/drop node, and launches into a span that has either (1)
OSC disabled or (2) OSC provisioned to 100base-FX.
