Reading Optical Diagnostics

Interpret module telemetry in context during commissioning and troubleshooting.

Overview

Diagnostics can reveal temperature, supply voltage, bias and optical power conditions. Values must be interpreted against the specific product limits and channel design.

Key planning checks

Compare transmit and receive readings at both ends.
Look for loss, asymmetry, temperature or threshold alarms.
Record stable baseline readings after turn-up.
Correlate telemetry with errors and physical inspection.

NRCube review note

Keep the unknowns visible

A plausible reading is not proof that the channel has adequate operating margin.
