Overview
SFP MSA Compliance
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 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 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.
Optical Interface
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 hotplugging 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.

ENGAGEMENT
SEQUENCE
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.

TX_FAULT
Functional Data I/O
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).
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.
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).

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.

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.
Compliance Prediction
Operating Temperature
The real-time diagnostic parameters can be monitored
to alert the system when operating limits are exceeded
and compliance cannot be ensured.
The AFCT-571xZ family is available in either Extended
(-10 to +85°C) or Industrial (-40 to +85°C) temperature
ranges.
Fault Isolation
Power Supply Noise
The diagnostic information can allow the host to
pinpoint the location of a link problem and accelerate
system servicing and minimize downtime.
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.
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.

Electrostatic Discharge (ESD)
Eye Safety
There are two conditions in which immunity to ESD
damage is important:
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.
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.
6
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.

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): 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 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 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 Ω differential lines which should be terminated with 100 Ω
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 Ω 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.
