General Features
The AFCT-575xZ family of SFP optical transceivers are
high performance, cost effective modules for serial op-
tical data communications applications ranging from
155-622 Mbps. They are designed to provide SONET/SDH
compliant connections for 622 Mbps at LR-1 and LR-2
reach links. This includes specifications for the signal cod-
ing, 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 LR-1 transceiver incorpo-
rates a 1300nm DFB laser. The transmitter section of the
LR-2 transceiver incorporates a 1550 nm DFB laser. For
each device the receiver section uses an MOVPE grown
planar PIN photodetector for low dark current and excel-
lent 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-575xZ 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-575xZ 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).
