Fault Isolation The fault isolation feature allows a host to quickly pinpoint Installation the location of a link failure, minimizing downtime. For The AFBR-57D9AMZ can be installed in any SFF-8074i optical links, the ability to identify a fault at a local device, compliant Small Form Pluggable (SFP) port regardless of remote device or cable plant is crucial to speeding service host equipment operating status.

Component Monitoring. Predictive Failure Identification The AFBR-57D9AMZ predictive failure feature allows a host to identify potential link problems before system perfor- mance 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, maintain- ing system uptime in the process. For applications where ultra-high system uptime is required, a digital 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). 2
