General Features  
SFP MSA Compliance  
The AFCT-576xZ family of SFP optical transceivers are high  
performance, cost effective modules for serial optical data  
The product package is compliant with the SFP MSA with  
the LC connector option. The SFP MSA includes specifica-  
communications applications ranging from 125-155 Mbps. tions for mechanical packaging and performance as well as  
They are designed to provide SONET/SDH compliant con-  
nections for 155 Mbps at short and intermediate reach  
links. This includes specifications for the signal coding,  
optical fiber and connector types, optical and electrical  
transmitter characteristics, optical and electrical receiver  
characteristics, jitter characteristics, and compliance test-  
ing methodology for the aforementioned. These transceiv-  
ers are qualified in accordance with GR-468-CORE.  
dc, ac and control signal timing and performance.  
The power supply is 3.3 V dc.  
The High Speed I/O (HSIO) signal interface is a Low Voltage  
Differential type. It is ac coupled and terminated internally  
to the module. The internal termination is a 100 Ohm dif-  
ferential load.  
Installation  
The transmitter section of the SR and IR transceivers incor-  
porate a 1300nm Fabry Perot (FP) laser. For each device the  
receiver section uses an MOVPE grown planar PIN photo-  
detector for low dark current and excellent responsivity. A  
positive-ECL logic interface simplifies interface to external  
circuitry. The receiver section contains an InGaAs/InP  
photo detector and a preamplifier mounted in an optical  
subassembly. This optical subassembly is coupled to a  
postamplifier/decision circuit on a circuit board.  
The AFCT-576xZ can be installed in any SFF-8074i compli-  
ant Small Form Pluggable (SFP) port regardless of host  
equipment operating status. The module is hot-plug-  
gable, allowing it to be installed while the host system  
is operating and online. Upon insertion, the transceiver  
housing makes initial contact with the host board SFP  
cage, mitigating potential damage due to electrostatic  
discharge (ESD).  
The AFCT-576xZ family of optical transceivers adds digital  
diagnostic monitoring to standard SFP functionality, en-  
abling fault isolation, components monitoring and failure  
prediction capabilities.
