Predictive Failure Identification The AFCT-739DMZ 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 applica- tions where ultra-high system uptime is required, a digi- tal SFP provides a means to monitor two real-time laser metrics associa ted with observing laser degradation and predicting failure: average laser bias current (Tx Bias) and average laser optical power (Tx Power). 2
