Predictive Failure Identification The AFBR-709DMZ 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 de- vice, maintaining system uptime in the process. For ap- plications where ultra-high system uptime is required, a digital SFP provides a means to monitor two real-time laser metrics asso ciated with laser degradation and pre- dicting failure: average laser bias current (Tx_Bias) and average laser optical power (Tx_Power). 2

Appendix: Rate Select Control RX and TX rates can be independently controlled by either hardware input pins or via register writes. Module electri- cal input pins 7 and 9 are used to select RX and TX rate respectively. Status of each logic level is reflected to register byte 110 bit 4 and 5 on address A2h as shown in the diagram below. RX and TX rates can also be controlled by register writes to byte 110 bit 3 and 118 bit 3. Power on default of these bits are logic low.
