For applica- tions where ultra-high system uptime is required, a digi- tal SFP provides a means to monitor two real-time laser metrics asso ciated with observing laser degradation and predicting failure: average laser bias current (Tx Bias) and average laser optical power (Tx Power). Compliance Prediction Compliance prediction is the ability to determine if an optical transceiver is operating within its operating and environmental requirements. AFBR-57R6APZ devices provide real-time access to transceiver internal supply voltage and temperature, allowing a host to identify po- tential component compliance issues. Received optical power is also available to assess compliance of a cable plant and remote transmitter. When operating out of re- quirements, the link cannot guarantee error free trans- mission. 2
