plant and remote transmitter. When operating out of re-
quirements, the link cannot guarantee error free trans-
mission.
Flammability
The AFBR-57J5APZ optical transceiver is made of metal
and high strength, heat resistant, chemical resistant and
UL 94V-0 flame retardant plastic.
Fault Isolation
The fault isolation feature allows a host to quickly
pinpoint the location of a link failure, minimizing
downtime. For optical links, the ability to identify a fault
at a local device, remote device or cable plant is crucial to
speeding service of an installation. AFBR-57J5APZ real-
time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and
Rx_Power can be used to assess local transceiver current
operating conditions. In addition, status flags Tx_Disable
and Rx Loss of Signal (LOS) are mirrored in memory and
available via the two-wire serial interface.
Predictive Failure Identification
The AFBR-57J5APZ 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, main-
taining 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
associated with observing laser degradation and pre-
dicting failure: average laser bias current (Tx_Bias) and
average laser optical power (Tx_Power).
Component Monitoring
Component evaluation is a more casual use of the
AFBR-57J5APZ real-time monitors of Tx_Bias, Tx_Power,
Vcc, Temperature and Rx_Power. Potential uses are as
debugging aids for system installation and design, and
transceiver parametric evaluation for factory or field qual-
ification. For example, temperature per module can be
observed in high density applications to facilitate thermal
evaluation of blades, PCI cards and systems.
Compliance Prediction:
Compliance prediction is the ability to determine if an
optical transceiver is operating within its operating and
environmental requirements. AFBR-57J5APZ devices
provide real-time access to transceiver internal supply
voltage and temperature, allowing a host to identify
potential component compliance issues. Received optical
power is also available to assess compliance of a cable
