Using the 2-wire serial interface defined environmental requirements. AFBR-57M5APZ devices in the SFF-8472 MSA, the AFBR-57M5APZ provides real provide real-time access to transceiver internal supply time temperature, supply voltage, laser bias current, voltage and temperature, allowing a host to identify laser average output power and received input power. potential component compliance issues. Received This information is in addition to conventional SFP optical power is also available to assess compliance of base data.

Fault Isolation Installation The fault isolation feature allows a host to quickly The AFBR-57M5APZ can be installed in any SFF-8074i pinpoint the location of a link failure, minimizing compliant Small Form Pluggable (SFP) port regardless downtime. For optical links, the ability to identify a fault of host equipment operating status. The AFBR-57M5APZ at a local device, remote device or cable plant is crucial is hot-pluggable, allowing the module to be installed to speeding service of an installation.

The I2C accessible memory page address 0xB0 is used internally by SFP for the test and diagnostic purposes and it is reserved. Predictive Failure Identification The AFBR-57M5APZ 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 SFP provides a means to monitor two real-time laser metrics asso ciated with observing laser degrada- tion and predicting failure: average laser bias current (Tx Bias) and average laser optical power (Tx Power). 2
