In addition, status flags Tx Disable and Rx Signal Predictive Failure Identification Detect are mirrored in memory and available via the two-wire serial interface. The predictive failure feature allows a host to identify potential link problems before system performance is impacted. Prior identification of link problems enables a host to service an application via fail over to a redundant link or replace a suspect device, maintaining system uptime in the process. For applications where ultra- high system uptime is required, a digital SFF provides a means to monitor two real-time laser metrics associated with observing laser degradation and predicting failure: average laser bias current (Tx Bias) and average laser optical power (Tx Power).
