SUMOOP

SUMOOP

Description

The SUMOOP indicates the total output optical power. This performance event includes three items: SUMOOPMAX, SUMOOPMIN, and SUMOOPCUR. The SUMOOPMAX item indicates the maximum value of the total output optical power. The SUMOOPMIN item indicates the minimum value of the total output optical power. The SUMOOPCUR item indicates the current value of the total output optical power.

Impact on System

  • If the total output power is excessively high, the input optical power of the downstream board may be excessively high. As a result, bit errors are generated in the services or even the services are interrupted. In addition, the receiver module of the board at the downstream station may be damaged.
  • If the total output power is excessively low, the input optical power of the downstream board may be excessively low. As a result, bit errors are generated in the services or even the services are interrupted.

Generation Principle and Possible Causes

To obtain this performance event, perform a check using the check circuit, and then calculate the result with software for conversion.

OUT_PWR_HIGH

The output optical power is too high. The value of the detected output optical power is more than the upper-threshold and the board reports the alarm in the following cases:
  • The value of the output optical power is more than the upper-threshold.
  • The optical power fails to be detected correctly.
  • The optical module is faulty.

OUT_PWR_LOW

The output optical power is too low. The value of the detected output optical power is less than the lower-threshold and the board reports the alarm in the following cases:
  • The value of the output optical power is less than the lower-threshold.
  • The optical power fails to be detected correctly.
  • The optical module is faulty.

Procedure

  1. If the current performance value is 2 dB or more than the history performance value but no alarm is reported, and if the power change is not caused by normal operations (such as capacity expansion or upgrading), see the method of handling the OUT_PWR_HIGH alarm to handle the performance event.
  2. If the current performance value is 2 dB or more less than the history performance value but no alarm is reported, and if the power change is not caused by normal operations (such as capacity expansion or upgrading), see the method of handling the OUT_PWR_LOW alarm to handle the performance event.
