General Features

The AFCT-576xZ family of SFP optical transceivers are high

performance, cost e ective 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 speci cations for the signal coding,

optical  ber 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 quali ed 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 simpli es interface to external

circuitry. The receiver section contains an InGaAs/InP

photo detector and a preampli er mounted in an optical

subassembly. This optical subassembly is coupled to a

postampli er/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 speci ca-

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

Di erential 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).

Transmitter Section

The transmitter section includes a 1310 nm Fabry-Perot

laser and a transmitter driver circuit. The driver circuit

maintains a constant optical power level provided that

the data pattern is valid for NRZ code. Connection to the

transmitter is provided via a LC optical connector.

The transmitter has full IEC 825 and CDRH Class 1 eye

safety.

TX_DISABLE

The transmitter output can be disabled by asserting pin

3, TX_DISABLE. A high signal asserts this function while

a low signal allows normal laser operation. The transmit-

ter output can also be disabled and monitored via the

2-wire serial interface. In the event of a transceiver fault,

such as the activation of the eye safety circuit, toggling

of the TX_DISABLE will reset the transmitter, as depicted

in Figure 2.

Figure 2. Typical Application Con guration

TX_FAULT

A laser fault or a low V

condition will activate the trans-

mitter fault signal, TX_FAULT, and disable the laser. This

signal is an open collector output (pull-up required on

the host board); A low signal indicates normal laser op-

eration and a high signal indicates a fault. The TX_FAULT

will be latched high when a laser fault occurs and is

cleared by toggling the TX_DISABLE input or power

cycling the transceiver. The TX_FAULT is not latched for

Low V

. The transmitter fault condition can also be

monitored via the two-wire serial interface (address A2,

byte 110, bit 2). By default, TX_FAULT is set to trigger on

hardware faults only.
