Installation
The AFCT-57M5ATP can be
installed in any SFF-8074i
compliant Small Form Pluggable
(SFP) port regardless of host
equipment operating status. The
AFCT-57M5ATP 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
Electro-Static Discharge (ESD).

Digital Diagnostic Interface and
Serial Identification
The 2-wire serial protocol is
based on the ATMEL
AT24C01A. The conventional
SFP EEPROM memory, bytes 0-
255 at memory address 0xA0,
is organized in compliance to
SFF-8074i. The 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 diagnostic information
allows the host system to
identify potential link problems.
Once identified, a “fail over”
technique can be used to
isolate and replace suspect
devices before system uptime is
impacted.

Compliance Prediction
The real-time diagnostic
parameters can be monitored
to alert the system when
operating limits are exceeded
and compliance cannot be
ensured.
Fault Isolation
The diagnostic information can
allow the host to pinpoint the
location of a link problem and
accelerate system servicing and
minimize downtime.
Component Monitoring
As part of the host system
monitoring, the real time
diagnostic information can be
combined with system level
monitoring to ensure system
reliability.
