Installation
The AFBR-57F5PZ can be installed in any SFF-8074i com-
pliant Small Form Pluggable (SFP) port regardless of host
equipment operating status. The AFBR-57F5PZ is hot-
pluggable, allowing the module to be installed while the
host system is operating and on-line. Upon insertion, the
transceiver housing makes initial contact with the host
board SFP cage, mitigating potential damage due to Elec-
tro-Static Discharge (ESD).
Digital Diagnostic Interface and Serial Identifi cation
The 2-wire serial interface is based on ATMEL AT24C01A
series EEPROM protocol and signaling detail. Conven-
tional EEPROM memory, bytes 0-255 at memory address
0xA0, is organized in compliance with SFF-8074i. New
digital diag nostic information, bytes 0-255 at memory ad-
dress 0xA2, is compliant to SFF-8472. The new diagnostic
information provides the opportunity for Predictive Fail-
ure Identifi cation, Com pliance Prediction, Fault Isolation
and Component Monitoring.
Predictive Failure Identifi cation
The AFBR-57F5PZ predictive failure feature allows a host
to identify potential link problems before system perfor-
mance is impacted. Prior identifi cation 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 ul-
tra-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 op-
tical power (Tx_Power).

Compliance Prediction
Compliance prediction is the ability to determine if an
optical transceiver is operating within its operating and
environmental requirements. AFBR-57F5PZ devices pro-
vide real-time access to transceiver internal supply volt-
age and temperature, allowing a host to identify potential
component compliance issues. Received optical power is
also available to assess compliance of a cable plant and
remote transmitter. When operating out of requirements,
the link cannot guarantee error free transmission.
Fault Isolation
The fault isolation feature allows a host to quickly pin-
point the location of a link failure, minimizing downtime.
For optical links, the ability to identify a fault at a local de-
vice, remote device or cable plant is crucial to speeding
service of an installation. AFBR-57F5PZ real-time monitors
of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power can
be used to assess local transceiver current operating con-
ditions. In addition, status fl ags Tx_Disable and Rx Loss of
Signal (LOS) are mirrored in memory and available via the
two-wire serial interface.
Component Monitoring
Component evaluation is a more casual use of the AFBR-
57F5PZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Tem-
perature and Rx_Power. Potential uses are as debugging
aids for system installation and design, and transceiver
parametric evaluation for factory or fi eld qualifi cation.
For example, temperature per module can be observed in
high density applications to facilitate thermal evaluation
of blades, PCI cards and systems.
