Overview
The AFCT-571xZ family is compliant with both IEEE
802.3Z (1000BASE-LX) and the SFP Multi-Source
Agreement (MSA) specification. These transceivers are
intended for premise, public and access networking
applications. They are qualified in accordance with GR-
468-CORE, and transmit data over single-mode (SM) fiber
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
functionality, enabling fault isolation, components
monitoring and failure prediction capabilities.
General Features
The AFCT-571xZ is compliant to 1 GbE specifications.
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
testing methodology for the aforementioned.
This transceiver is capable of implementing both Single
Mode (SM) and Multimode (MM) optical fiber
applications in that order of precedence in the event of
conflicting specifications. In addition, the SM link type
exceeds the 2 m to 5 km 1000BASE-LX specification by
achieving compliance over 2 m to 10 km. The MM link
type is expected to meet the 62.5 µm MMF specification
when used with an “offset launch” fiber.

SFP MSA Compliance
The product package is compliant with the SFP MSA
with the LC connector option. The SFP MSA includes
specifications 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 differential 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,
electrical-interface first, under finger-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, first contact is made by the
housing ground shield, discharging any potentially
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 transmitter, as depicted in
Figure 4.

HOST BOARD
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 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.
RX_LOS
The receiver section contains a loss of signal (RX_LOS)
circuit to indicate when the optical input signal power
is insufficient for Gigabit Ethernet 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 A2h, byte 110, bit 1).
Functional Data I/O
Avago’s AFCT-571xZ transceiver is designed to accept
industry standard differential 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
Identification
The AFCT-571xZ family complies with the SFF-8074i
specification, which defines the module’s serial
identification 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
defined 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
prediction, fault isolation, and component monitoring
capabilities.
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 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).
The digital diagnostic interface also adds the ability to
disable the transmitter (TX_DISABLE), monitor for
Transmitter 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 specifications are available from the SFF
Committee at http://www.sffcommittee.org.
Predictive Failure Identification
The diagnostic information allows the host system to
identify potential link problems. Once identified, a fail-
over technique can be used to isolate and replace
suspect devices before system uptime is impacted.

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
recommended power supply filter shown in Figure 3.
Regulatory Compliance
The transceiver regulatory compliance is provided in
Table 1 as a figure of merit to assist the designer. The
overall equipment design will determine the certification
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
availability 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 reflow, 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 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
including the use of grounded wrist straps, work
benches, and floor 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
performance 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 fields 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 4.7K – 10 K 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 K
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 4.7 K – 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 must be between 370 and 2000 mV differential (185 – 1000 mV single ended) according to the MSA. Typically it will be
1500mv differential.
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 in-rush
current will typically be no more than 30 mA above steady state supply current 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). However, the applicable recommended differential voltage swing is found in Table 5.
