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.

Using the 2-wire serial interface, the AFCT-5765Z pro-

vides real time access to transceiver internal supply volt-

age and temperature, transmitter output power, laser

bias current and receiver average input power, allowing

a host to predict system compliance issues. These ﬁve

parameters are internally calibrated, per the MSA. New

digital diagnostic information is accessed per SFF-8472

using EEPROM bytes 0-255 at memory address 0xA2

(A2h).

Receiver Section

The receiver section for the AFCT-576xZ contains an

InGaAs/InP photo detector and a preampliﬁer mounted

in an optical subassembly. This optical subassembly is

coupled to a post ampliﬁer/decision circuit on a circuit

board. The design of the optical subassembly provides

better than 12 dB Optical Return Loss (ORL).

Connection to the receiver is provided via a LC optical

connector.

The digital diagnostic interface also adds the ability to

disable the transmitter (TX_DISABLE), monitor for Trans-

mitter Faults (TX_FAULT) and monitor for Receiver Loss

of Signal (RX_LOS).

RX_LOS

The receiver section contains a loss of signal (RX_LOS)

circuit to indicate when the optical input signal power

is insuﬃcient for SONET/SDH compliance. A high signal

indicates loss of modulated signal, indicating link failure

such as a broken ﬁber or a failed transmitter. RX_LOS can

be also be monitored via the two-wire serial (address A2,

byte 110, bit 1).

Contents of the MSA-compliant serial ID memory are

shown in Tables 3 to 7. The SFF-8074i and SFF-8472

speciﬁcations are available from the SFF Committee at

http://www.sﬀcommittee.org.

The I2C accessible memory page address 0xB0 is used

internally by SFP for the test and diagnostic purposes

and it is reserved.

Electrostatic Discharge (ESD)

Caution

There are two conditions in which immunity to ESD dam-

age is important:

The AFCT-576xZ contains no user-serviceable parts. Tam-

pering with or modifying the performance of the AFCT-

576xZ will result in voided product warranty. It may also

result in improper operation of the transceiver circuitry,

and possible over-stress of the laser source. Device deg-

radation or product failure may result. Connection of the

AFCT-576xZ to a non-approved optical source, operating

above the recommended absolute maximum conditions

may be considered an act of modifying or manufacturing

a laser product. The person(s) performing such an act

is required by law to re-certify and re-identify the laser

product under the provisions of U.S. 21 CF.

The ﬁrst condition is static discharge to the transceiver

during handling such as when the transceiver is inserted

into the transceiver port. To protect the transceiver, it is

important to use normal ESD handling precautions includ-

ing the use of grounded wrist straps, work benches, and

ﬂoor mats in ESD controlled areas. The ESD sensitivity of

the AFCT-576xZ is compatible with typical industry pro-

duction environments.

The second condition is static discharge to the exterior

of the host equipment chassis after installation. To the

extent that the duplex LC optical interface is exposed

to the outside of the host equipment chassis, it may be

subject to system-level ESD requirements. The ESD per-

formance of the AFCT-576xZ exceeds typical industry

standards. Table 1 documents ESD immunity to both of

these conditions.

Handling Precautions

The AFCT-576xZ can be damaged by current surges or

overvoltage. Power supply transient precautions should

be taken, and normal handling precautions for electro-

static sensitive devices should be taken.

Optical Power Budget

Electromagnetic Interference (EMI)

The worst-case Optical Power Budget (OPB) in dB for a

ﬁber-optic link is determined by the diﬀerence between

the minimum transmitter output optical power (dBm

avg) and the lowest receiver sensitivity (dBm avg). This

OPB provides the necessary optical signal range to es-

tablish a working ﬁber-optic link. The OPB is allocated for

the ﬁber-optic cable length and the corresponding link

penalties. For proper link performance, all penalties that

aﬀect the link performance must be accounted for within

the link optical power budget.

Most equipment designs using the AFCT-576xZ SFPs are

subject to the requirements of the FCC in the United

States, CENELEC EN55022 (CISPR 22) in Europe and VCCI

in Japan. The metal housing and shielded design of the

transceiver minimize EMI and provide excellent EMI per-

formance.

EMI Immunity

The AFCT-576xZ transceivers have a shielded design to

provide excellent immunity to radio frequency electro-

magnetic ﬁelds which may be present in some operating

environments.

Process Plug

This transceiver is supplied with a process plug for

protection of the optical port within the LC connector

receptacle. This process plug prevents contamination

during handling, shipping and storage. It is made of a

high-temperature, molded sealing material that can

withstand +85 °C.

Eye Safety

The AFCT-576xZ transceivers provide Class 1 eye safety

by design. Avago Technologies has tested the transceiver

design for regulatory compliance, under normal operat-

ing conditions and under a single fault condition. See

Table 1.

LC SFP Cleaning Recommendations

In the event of contamination of the optical ports, the

recommended cleaning process is the use of forced ni-

trogen. If contamination is thought to have remained, the

optical ports can be cleaned using a NTT international

Cletop stick type (diam. 1.25 mm) and HFE7100 cleaning

ﬂuid.

Flammability

The AFCT-576xZ family of SFPs is compliant to UL 94V-0.

Customer Manufacturing Processes

This module is pluggable and is not designed for aqueous

wash, IR reﬂow, or wave soldering processes.

Notes:

1. TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10K resistor on the host board. Pull up voltage between

2.0 V and VccT, R+0.3 V. When high, output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will

be pulled to < 0.8 V. By default, TX_FAULT is set to trigger on hardware faults only.

2. TX Disable input is used to shut down the laser output per the state table below with an external 4.7 - 10 K pull-up resistor.

Low (0 - 0.8 V): Transmitter on

Between (0.8 V and 2.0 V): Undeﬁned

High (2.0 - 3.465 V): Transmitter Disabled

Open: Transmitter Disabled

3. MOD-DEF 0,1,2. These are the module deﬁnition pins. They should be pulled up with a 4.7 - 10 K resistor on the host board to a supply less

than VccT +0.3 V or VccR+0.3 V.

MOD-DEF 0 is grounded by the module to indicate that the module is present

MOD-DEF 1 is clock line of two wire serial interface for optional serial ID

MOD-DEF 2 is data line of two wire serial interface for optional serial ID

4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7K - 10 K resistor on the host board to a

supply < VccT,R+0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as deﬁned by

the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V.

5. RD-/+: These are the diﬀerential receiver outputs. They are ac coupled 100 diﬀerential lines which should be terminated with 100 diﬀerential

at the user SERDES. The ac coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will

be between 320 and 2000 mV diﬀerential (160 - 1000 mV single ended) when properly terminated.

6. VccR and VccT are the receiver and transmitter power supplies. They are deﬁned as 3.135 - 3.465 V at the SFP connector pin. The maximum sup-

ply current is 250 mA and the associated inrush current will be no more than 30 mA above steady state after 500 nanoseconds.

7. TD-/+: These are the diﬀerential transmitter inputs. They are ac coupled diﬀerential lines with 100 diﬀerential termination inside the module.

The ac coupling is done inside the module and is thus not required on the host board. The inputs will accept diﬀerential swings of 500 - 2400

mV (250 - 1200 mV single ended), though it is recommended that values between 500 and 1200 mV diﬀerential (250 - 600 mV single ended) be

used for best EMI performance.
