General Features

The AFCT-575xZ family of SFP optical transceivers are

high performance, cost eective 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 short and

intermediate reach links. This includes specications for

the signal coding, optical ber and connector types, opti-

cal and electrical transmitter characteristics, optical and

electrical receiver characteristics, jitter characteristics, and

compliance testing methodology for the aforementioned.

These transceivers 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-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 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-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).

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 VCC 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 VCC. 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.

HOST BOARD

Receiver Section

The receiver section for the AFCT-575xZ 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 SONET/SDH 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 A2,

byte 110, bit 1).

Functional Data I/O

Avago’s AFCT-575xZ transceiver is designed to accept

industry standard dierential signals. The transceiver pro-

vides 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-575xZ family complies with the SFF-8074i spec-

i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 ad-

dress 0xA0 (A0h).

As an enhancement to the conventional SFP interface

dened in SFF-8074i, the AFCT-5755Z is also compliant

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

enhancement adds digital diagnostic monitoring to stan-

dard SFP functionality, enabling failure prediction, fault

isolation, and component monitoring capabilities.

Using the 2-wire serial interface, the AFCT-5755Z 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 pre-

dict 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 3 to 7. The SFF-8074i and SFF-8472

specications are available from the SFF Committee at

http://www.scommittee.org.

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.

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 ser-

vicing and minimize downtime.

Component Monitoring

As part of the host system monitoring, the real time di-

agnostic information can be combined with system level

monitoring to ensure system reliability.

Operating Temperature

The AFCT-575xZ family is available in either Extended

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

ranges.

Power Supply Noise

The AFCT-575xZ can withstand an injection of PSN on the

VCC lines of 100 mV ac without a degradation in eye mask

margin 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 recommended 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cation level.

Electrostatic Discharge (ESD)

There are two conditions in which immunity to ESD dam-

age 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 precautions includ-

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

oor mats in ESD controlled areas. The ESD sensitivity of

the AFCT-575xZ 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

performance of the AFCT-575xZ exceeds typical industry

standards. Table 1 documents ESD immunity to both of

these conditions.

Electromagnetic Interference (EMI)

Most equipment designs using the AFCT-575xZ 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-575xZ transceivers have a shielded design to

provide excellent immunity to radio frequency electro-

magnetic elds which may be present in some operating

environments.

Eye Safety

The AFCT-575xZ 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.

Flammability

The AFCT-575xZ family of SFPs is compliant to UL 94V-

Customer Manufacturing Processes

This module is pluggable and is not designed for aque-

ous wash, IR reow, or wave soldering processes.

Caution

The AFCT-575xZ contains no user-serviceable parts. Tam-

pering with or modifying the performance of the AFCT-

575xZ 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-575xZ 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.

Handling Precautions

The AFCT-575xZ 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

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

ber-optic link is determined by the dierence 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 ber-optic link. The OPB is allocated

for the ber-optic cable length and the corresponding

link penalties. For proper link performance, all penalties

that aect the link performance must be accounted for

within the link optical power budget.

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.

LC SFP Cleaning Recommendations

In the event of contamination of the optical ports, the

recommended cleaning process is the use of forced

nitrogen. If contamination is thought to have remained,

the optical ports can be cleaned using a NTT interna-

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

cleaning uid.

Notes:

1. TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ 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 KΩ pull-up 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 4.7K - 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 100Ω dierential lines which should be terminated with 100Ω 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 will

be between 500 and 2000 mV dierential (250 - 1000 mV single ended) when properly terminated.

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 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 dierential transmitter inputs. They are ac coupled dierential lines with 100Ω 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), though it is recommended that values between 500 and 1200 mV dierential (250 - 600 mV single ended) be

used for best EMI performance.
