Digital Diagnostic Interface
and Serial Identification
The 2-wire serial interface is
based on ATMEL AT24C01A
series EEPROM protocol and
signaling detail. Conventional
SFP EEPROM memory, bytes
0-255 at memory address 0xA0,
is organized in compliance with
SFF-8074i. New digital
diagnostic information, bytes
0-255 at memory address 0xA2,
is compliant to SFF-8472. The
new diagnostic information
provides the opportunity for
Predictive Failure Identification,
Compliance Prediction, Fault
Isolation and Component
Monitoring.
Predictive Failure Identification
The AFCT-57R5ATPZ 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, 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 predicting failure: average
laser bias current (Tx_Bias) and
average laser optical power
(Tx_Power).
Compliance Prediction
Compliance prediction is the
ability to determine if an optical
transceiver is operating within
its operating and environmental
requirements. AFCT-57R5ATPZ
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 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 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. AFCT-57R5ATPZ
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.
Component Monitoring
Component evaluation is a more
casual use of the AFCT-
57R5ATPZ 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 qualification. For
example, temperature per
module can be observed in high
density applications to facilitate
thermal evaluation of blades,
PCI cards and systems.
