General Features
The AFCT-576xZ family of SFP optical transceivers are high
performance, cost effective modules for serial optical data
communications applications ranging from 125-155 Mbps.
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.
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 family of optical transceivers adds digital
diagnostic monitoring to standard SFP functionality, en-
abling fault isolation, components monitoring and failure
prediction capabilities.

SFP MSA Compliance
The product package is compliant with the SFP MSA with
the LC connector option. The SFP MSA includes specifica-
tions for mechanical packaging and performance as well as
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 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).
