TCX1000-RDM20 Total Power Monitor Ranges

 

This topic describes the power ranges for total power monitoring.

Power Ranges for Power Monitors

Two power ranges are defined for each power monitor:

  • Operation — The operation range is the optical power range over which the channel monitoring and control is expected to meet all operating performance requirements.

  • Alarm — The alarm range is the optical power range over which the monitoring is still required in order to have proper system alarming and fault detection. The alarm range maximum and minimum define the hardware limits (power readings outside of hardware limits are considered invalid).

Table 1 describes the total power monitoring range for the universal ports.
