RoHS Compliant Digital Diagnostic Optical Transceiver
Data Sheet
Description
Avago Technologies’ AFCT-57D5ANPZ optical transceiver 
supports high-speed serial links over singlemode optical 
fiber  at  signaling  rates  up  to  8.5  GBd.  Compliant  with 
Small Form Pluggable (SFP) Multi Source Agreement (MSA) 
mechanical  and  electrical  specifications  for  LC  Duplex 
transceivers, ANSI Fibre Channel for FC-PI-4 and FC-PI-2 for 
gigabit applications. The part is electrically interoperable 
with SFP conformant devices.
The  AFCT-57D5ANPZ  is  a  multi-rate  1310nm  DFB  SFP 
which  ensures  compliance  to  8.5/4.25/2.125  GBd  Fibre 
Channel specifications without the need  for  Rate  Select. 
The  AFCT-57D5ANPZ  will  ignore  both  Rate  Select  pin 
and control bit inputs (ie. no connect inside the SFP). This 
simplifies Fibre Channel host auto-negotiation algorithms, 
layout and software.
