Understanding the Performance Monitors and TCAs for IPLCs

Performance monitors enable you to examine and diagnose the health, working capacity, operational efficiency, and the traffic-handling condition of the integrated photonic line cards modules (IPLCs) at various points on the optical IPLC hardware. You can enable configure threshold-crossing alarms (TCA) for the optical IPLC performance monitors. TCAs are alarms that are activated when a certain configurable threshold—near-end measurement threshold or far-end measurement threshold—is crossed and remains so for 15 minutes

The IPLC supports the optical performance monitors listed in Table 1.

Table 1: IPLC Optical Performance Monitors
Performance Monitor	15 Min Bin	24 Hr Bin	TCA High	TCA Low
OSC TX power	Yes	Yes	Yes	Yes
OSC RX power	Yes	Yes	Yes	Yes
OSC/FPGA estimated fiber loss	Yes	Yes	No	No
Line OUT VOA attenuation	Yes	Yes	Yes	Yes
EDFA Input power (for both EDFAs)	Yes	Yes	Yes	Yes
EDFA Output power (for both EDFAs)	Yes	Yes	Yes	Yes
EDFA Signal output power (for both EDFAs)	Yes	Yes	Yes	Yes
EDFA Pump current (for both EDFAs)	Yes	Yes	Yes	Yes
EDFA Pump temperature (for both EDFAs)	Yes	Yes	Yes	Yes
OCM power readings (96 channels x 1 monitoring points)	Yes	Yes	Yes	Yes
Power monitor at ADD port	Yes	Yes	Yes	Yes
Power monitor at EXPRESS IN port	Yes	Yes	Yes	Yes

Each performance monitor supports:

15-minute and 24-hour binning
Low and high threshold levels as described in Table 2.
