Digital Diagnostic Function

The LRXP1310-20ATL(10/1G) supports the 2-wire serial communication protocol defined in SFF-8472. This product accesses digital diagnostic information through a 2-wire interface at address 0xA2. Digital diagnostics default to internal calibration. The internal microcontroller unit continuously monitors device operating parameters in real time, including transceiver temperature, laser bias current, transmit optical power, receive optical power, and transceiver supply voltage. The module implements SFF-8472 alarm functionality, alerting users when specific operating parameters exceed factory-set normal ranges.
