Overview

The AFCT-571xZ family is compliant with both IEEE

802.3Z (1000BASE-LX) and the SFP Multi-Source

Agreement (MSA) speci cation. These transceivers

are intended for premise, public and access network-

ing applications. They are quali ed in accordance with

GR-468-CORE, and transmit data over single-mode

(SM)  ber for a link distance of 10 km, in excess of the

standard.

The AFCT-5715Z family of optical transceivers adds

digital diagnostic monitoring to standard SFP function-

ality, enabling fault isolation, components monitoring

and failure prediction capabilities.

General Features

The AFCT-571xZ is compliant to 1 GbE speci cations.

This includes speci cations for the signal coding, optical

 ber and connector types, optical and electrical trans-

mitter characteristics, optical and electrical receiver

characteristics, jitter characteristics, and compliance

testing methodology for the aforementioned.

This transceiver is capable of implementing both Single

Mode (SM) and Multimode (MM) optical  ber applica-

tions in that order of precedence in the event of con-

 icting speci cations. In addition, the SM link type

exceeds the 2 m to 5 km 1000BASE-LX speci cation by

achieving compliance over 2 m to 10 km. The MM link

type is expected to meet the 62.5 μm MMF speci cation

when used with an “o set launch”  ber.

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 di erential load.

Installation

The AFCT-571xZ can be installed in or removed from

any MSA-compliant Pluggable Small Form Factor (SFP)

port regardless of whether the host equipment is

operating or not. The module is simply inserted, electri-

cal-interface  rst, under  nger-pressure. Controlled hot-

plugging is ensured by 3-stage pin sequencing at the

electrical interface. This printed circuit board card-edge

connector is depicted in Figure 2.

As the module is inserted,  rst contact is made by

the housing ground shield, discharging any poten-

tially component-damaging static electricity. Ground

pins engage next and are followed by Tx and Rx

power supplies. Finally, signal lines are connected. Pin

functions and sequencing are listed in Table 2.

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 8B/10B code. Connection to the

transmitter is provided via a LC optical connector.

The transmitter has full IEC 60825 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. In addition,

via the 2-wire serial interface the transmitter output can

be disabled (address A2h, byte 110, bit 6) or monitored

(address A2h, byte 110, bit 7). The contents of A2h, byte

110, bit 6 are logic OR’d with hardware Tx_Disable (pin

3) to control transmitter operation. In the event of a

transceiver fault, such as the activation of the eye safety

circuit, toggling of the TX_DISABLE will reset the trans-

mitter, as depicted in Figure 4.

SFP MODULE

HOST BOARD

Functional Data I/O

Avago’s AFCT-571xZ transceiver is designed to accept

industry standard di erential signals. The transceiver

provides an AC-coupled, internally terminated data

interface. Bias resistors and coupling capacitors have

been included within the module to reduce the number

of components required on the customer’s board.

Figure 2 illustrates the recommended interface circuit.

Digital Diagnostic Interface and Serial Identi cation

The AFCT-571xZ family complies with the SFF-8074i

speci cation, which de nes the module’s serial identi -

cation protocol to use the 2-wire serial CMOS EEPROM

protocol of the ATMEL AT24C01A or similar. Standard

SFP EEPROM bytes 0-255 are addressed per SFF-8074i at

memory address 0xA0 (A0h).

As an enhancement to the conventional SFP interface

de ned in SFF-8074i, the AFCT-5715Z is also compliant

to SFF-8472 (the digital diagnostic interface for SFP).

This enhancement adds digital diagnostic monitoring

to standard SFP functionality, enabling failure predic-

tion, fault isolation, and component monitoring capa-

bilities.

Using the 2-wire serial interface, the AFCT-5715Z

provides real time access to transceiver internal supply

voltage and temperature, transmitter output power,

laser bias current and receiver average input power,

allowing a host to predict system compliance issues.

These  ve 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).

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).

Contents of the MSA-compliant serial ID memory are

shown in Tables 10 through 14. The SFF-8074i and

SFF-8472 speci cations are available from the SFF

Committee at http://www.s committee.org.

The I2C accessible memory page address 0xB0 is used

internally by SFP for the test and diagnostic purposes

and it is reserved.

Predictive Failure Identi cation

The diagnostic information allows the host system

to identify potential link problems. Once identi ed, a

fail-over technique can be used to isolate and replace

suspect devices before system uptime is impacted.

TX_FAULT

A laser fault or a low VCC condition will activate the

transmitter 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

operation 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 VCC. The transmitter fault condition can also

be monitored via the two-wire serial interface (address

A2h, byte 110, bit 2).

Eye Safety Circuit

Under normal operating conditions, the laser power

will be maintained below the eye-safety limit. If the

eye safety limit is exceeded at any time, a laser fault will

occur and the TX_FAULT output will be activated.

Receiver Section

The receiver section for the AFCT-571xZ contains an

InGaAs/InP photo detector and a preampli er mounted

in an optical subassembly. This optical subassembly is

coupled to a post ampli er/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.

RX_LOS

The receiver section contains a loss of signal (RX_LOS)

circuit to indicate when the optical input signal power

is insu cient for Gigabit Ethernet compliance. A high

signal indicates loss of modulated signal, indicating link

failure such as a broken  ber or a failed transmitter. RX_

LOS can be also be monitored via the two-wire serial

(address A2h, byte 110, bit 1).

Operating Temperature

The AFCT-571xZ family is available in either Extended

(-10 to +85°C) or Industrial (-40 to +85°C) temperature

ranges.

Power Supply Noise

The AFCT-571xZ can withstand an injection of PSN on

the VCC lines of 100 mV ac with a degradation in eye

mask margin of up to 10% on the transmitter and a 1

dB sensitivity penalty on the receiver. This occurs when

the product is used in conjunction with the MSA rec-

ommended power supply  lter shown in Figure 3.

Regulatory Compliance

The transceiver regulatory compliance is provided in

Table 1 as a  gure of merit to assist the designer. The

overall equipment design will determine the certi ca-

tion level.

Compliance Prediction

The real-time diagnostic parameters can be monitored

to alert the system when operating limits are exceeded

and compliance cannot be ensured.

Fault Isolation

The diagnostic information can allow the host to

pinpoint the location of a link problem and accelerate

system servicing and minimize downtime.

Component Monitoring

As part of the host system monitoring, the real time

diagnostic information can be combined with system

level monitoring to ensure system reliability.

Application Support

An Evaluation Kit and Reference Designs are available

to assist in evaluation of the AFCT-571xZ SFPs. Please

contact your local Field Sales representative for avail-

ability and ordering details.

Eye Safety

The AFCT-571xZ transceivers provide Class 1 eye

safety by design. Avago Technologies has tested the

transceiver design for regulatory compliance, under

normal operating conditions and under a single fault

condition. See Table 1.

Flammability

The AFCT-571xZ family of SFPs is compliant to UL

94V-0.

Customer Manufacturing Processes

This module is pluggable and is not designed for

aqueous wash, IR re ow, or wave soldering processes.

Caution

The AFCT-571xZ contains no user-serviceable parts.

Tampering with or modifying the performance of the

AFCT-571xZ 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 degradation or product failure may result.

Connection of the AFCT-571xZ 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.

Electrostatic Discharge (ESD)

There are two conditions in which immunity to ESD

damage is important:

The  rst 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 precau-

tions including the use of grounded wrist straps, work

benches, and  oor mats in ESD controlled areas. The ESD

sensitivity of the AFCT-571xZ is compatible with typical

industry production 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-571xZ exceeds typical industry

standards. Table 1 documents ESD immunity to both of

these conditions.

Electromagnetic Interference (EMI)

Most equipment designs using the AFCT-571xZ 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 performance.

EMI Immunity

The AFCT-571xZ transceivers have a shielded design

to provide excellent immunity to radio frequency

electromagnetic  elds which may be present in some

operating environments.

Notes:

1. TX Fault is an open collector/drain output which should be pulled up externally with a 4.7KΩ – 10 KΩ resistor on the host board to a supply

<VccT+0.3 V or VccR+0.3 V. When high, this 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.

2. TX disable input is used to shut down the laser output per the state table below. It is pulled up within the module with a 4.7-10 KΩ resistor.

Low (0 – 0.8 V): Transmitter on

Between (0.8 V and 2.0 V): Unde ned

High (2.0 – 3.465 V): Transmitter Disabled

Open: Transmitter Disabled

3. Mod-Def 0,1,2. These are the module de nition pins. They should be pulled up with a 4.7-10 KΩ 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 4.7 KΩ – 10 KΩ 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 de ned

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 di erential receiver outputs. They are AC coupled 100 Ω di erential lines which should be terminated with 100 Ω

di erential 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 must be between 370 and 2000 mV di erential (185 – 1000 mV single ended) according to the MSA. Typically it will be 1500mv

di erential.

6. VccR and VccT are the receiver and transmitter power supplies. They are de ned as 3.135 – 3.465 V at the SFP connector pin. The in-rush

current will typically be no more than 30 mA above steady state supply current after 500 nanoseconds.

7. TD-/+: These are the di erential transmitter inputs. They are AC coupled di erential lines with 100 Ω di erential 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 di erential swings of

500 – 2400 mV (250 – 1200 mV single ended). However, the applicable recommended di erential voltage swing is found in Table 5.
