Overview
The AFBR-571xZ family of optical transceivers are com-
pliant with the specifications set forth in the IEEE802.3
(1000BASE-SX) and the Small Form-Factor Pluggable (SFP)
Multi-Source Agreement (MSA). This family of transceivers
is qualified in accordance with Telcordia GR-468-CORE.
Its primary application is servicing Gigabit Ethernet links
between optical networking equipment.
The AFBR-571xZ offers maxi mum flexibility to designers,
manufacturers, and operators of Gigabit Ethernet net-
working equipment. A pluggable architec ture allows the
module to be installed into MSA standard SFP ports at
any time – even with the host equipment operating and
online. This facilitates the rapid configuration of equip-
ment to precisely the user’s needs – reducing inventory
costs and network downtime. Compared with traditional
transceivers, the size of the Small Form Factor package
enables higher port densities.
Module Diagrams
Figure 1 illustrates the major functional components of the
AFBR-571xZ. The external configuration of the module is
depicted in Figure 7. Figure 8 depicts the panel and host
board footprints.
3
Installation
The AFBR-571xZ can be installed in or removed from any
MSA-compliant Pluggable Small Form Factor port regard-
less 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 com-
ponent-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 the Transmitter Optical
Sub assembly (TOSA) and laser driver circuitry. The TOSA,
containing an 850 nm VCSEL (Vertical Cavity Surface Emit-
ting Laser) light source, is located at the optical interface and
mates with the LC optical connector. The TOSA is driven by
a custom IC, which converts differential logic signals into an
analog laser diode drive current. This Tx driver circuit regu-
lates the optical power at a constant level provided the data
pattern is DC balanced (8B10B code for example).
Transmit Disable (Tx_Disable)
The AFBR-571xZ accepts a TTL and CMOS compatible
transmit disable control signal input (pin 3) which shuts
down the transmitter optical output. A high signal imple-
ments this function while a low signal allows normal
transceiver operation. In the event of a fault (e.g. eye
safety circuit activated), cycling this control signal resets
the module as depicted in Figure 6. An internal pull-up
resistor disables the transceiver transmitter until the host
pulls the input low. Host systems should allow a 10ms
interval between successive assertions of this control
signal. Tx_Disable can also be asserted via the 2-wire serial
interface (address A2h, byte 110, bit 6) and 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 opera-
tion.
Transmit Fault (Tx_Fault)
A catastrophic laser fault will activate the transmitter signal,
TX_FAULT, and disable the laser. This signal is an open collec-
tor 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 transmitter fault condition
can also be monitored via the 2-wire serial interface (address
A2, byte 110, bit 2).
Eye Safety Circuit
The AFBR-571xZ provides Class 1 eye safety by design and
has been tested for compliance with the requirements
listed in Table 1. The eye safety circuit continu ously moni-
tors optical output power levels and will disable the trans-
mitter and assert a TX_FAULT signal upon detecting an
unsafe condition. Such unsafe conditions can be created
by inputs from the host board (Vcc fluxuation, unbalanced
code) or faults within the module.
Receiver Section
The receiver section includes the Receiver Optical Subas-
sembly (ROSA) and amplification/quantization circuitry. The
ROSA, containing a PIN photodiode and custom trans-im-
pedance preamplifier, is located at the optical interface and
mates with the LC optical connector. The ROSA is mated to
a custom IC that provides post-amplification and quantiza-
tion. Also included is a Loss Of Signal (LOS) detection circuit.
Receiver Loss of Signal (Rx_LOS)
The Loss Of Signal (LOS) output indicates an unusable
optical input power level. The Loss Of Signal thresholds
are set to indicate a definite optical fault has occurred
(e.g., disconnected or broken fiber connection to receiver,
failed transmitter, etc.).
The post-amplification IC includes transition detection
circuitry which monitors the ac level of incoming optical
signals and provides a TTL/CMOS compatible status signal
to the host (pin 8). An adequate optical input results in a
low Rx_LOS output while a high Rx_LOS output indicates
an unusable optical input. The Rx_LOS thresholds are fac-
tory-set so that a high output indicates a definite optical
fault has occurred. For the AFBR-5715Z family, Rx_LOS can
also be monitored via the 2-wire serial interface (address
A2h, byte 110, bit 1).
4
Functional I/O
The AFBR-571xZ accepts industry standard differential
signals such as LVPECL and CML within the scope of the
SFP MSA. To simplify board requirements, transmitter bias
resistors and ac coupling capacitors are incorporated, per
SFF-8074i, and hence are not required on the host board.
The module is AC-coupled and internally terminated.
Figure 3 illustrates a recommended interface circuit to
link the AFBR-571xZ to the supporting Physical Layer
integrated circuits.
Timing diagrams for the MSA compliant control signals
implemented in this module are depicted in Figure 6.
The AFBR-571xZ interfaces with the host circuit board
through twenty I/O pins (SFP electrical connector)
identified by function in Table 2. The AFBR-571xZ high
speed transmit and receive interfaces require SFP MSA
compliant signal lines on the host board. The Tx_Disable,
Tx_Fault, and Rx_LOS lines require TTL lines on the host
board (per SFF-8074i) if used. If an application chooses
not to take advantage of the functionality of these pins,
care must be taken to ground Tx_Disable (for normal
operation).

Digital Diagnostic Interface and Serial Identification
(EEPROM)
The entire AFBR-571xZ family complies with the SFF-
8074i SFP specification. The AFBR-5715Z family further
complies with SFF-8472, the SFP specification for Digital
Diagnostic Monitoring Interface. Both specifications can
be found at http://www.sffcommittee.org.
The AFBR-571xZ features an EEPROM for Serial ID, which
contains the product data stored for retrieval by host
equipment. This data is accessed via the 2-wire serial
EEPROM protocol of the ATMEL AT24C01A or similar, in
compliance with the industry standard SFP Multi-Source
Agreement. The base EEPROM memory, bytes 0-255 at
memory address 0xA0, is organized in compliance with
SFF-8074i. Contents of this serial ID memory are shown
in Table 10.
The I2C accessible memory page address 0xB0 is used
internally by SFP for the test and diagnostic purposes
and it is reserved.
5
As an enhancement to the conventional SFP interface
defined in SFF-8074i, the AFBR-5715Z family is compliant
to SFF-8472 (digital diagnostic interface for optical trans-
ceivers). This new digital diagnostic information is stored
in bytes 0-255 at memory address 0xA2.Using the 2-wire
serial interface defined in the MSA, the AFBR-5715Z
provides real time temperature, supply voltage, laser
bias current, laser average output power and received
input power. These parameters are internally calibrated,
per the MSA.
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).
The new diagnostic information provides the oppor-
tunity for Predictive Failure Identification, Compliance
Prediction, Fault Isolation and Component Monitoring.
Predictive Failure Identification
The predictive failure feature allows a host to identify
potential link problems before system performance is
impacted. Prior identification of link problems enables
a host to service an application via “fail over” to a redun-
dant link or replace a suspect device, maintaining system
uptime in the process. For applications where ultra-high
system uptime is required, a digital SFP provides a means
to monitor two real-time laser metrics associated with ob-
serving laser degradation and predicting failure: average
laser bias current (Tx_Bias) and average laser optical power
(Tx_Power).
Compliance Prediction
Compliance prediction is the ability to determine if an
optical transceiver is operating within its operating and
environmental requirements. AFBR-5715Z devices provide
real-time access to transceiver internal supply voltage
and temperature, allowing a host to identify potential
component compliance issues. Received optical power is
also available to assess compliance of a cable plant and
remote transmitter. When operating out of requirements,
the link cannot guarantee error free transmission.
Fault Isolation
The fault isolation feature allows a host to quickly pin-
point the location of a link failure, minimizing downtime.
For optical links, the ability to identify a fault at a local
device, remote device or cable plant is crucial to speeding
service of an installation. AFBR-5715Z real-time monitors
of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power
can be used to assess local transceiver current operating
conditions. In addition, status flags Tx_Disable and Rx Loss
of Signal (LOS) are mirrored in memory and available via
the two-wire serial interface.
Component Monitoring
Component evaluation is a more casual use of the AFBR-
5715Z real-time monitors of Tx_Bias, Tx_Power, Vcc, Tem-
perature and Rx_Power. Potential uses are as debugging
aids for system installation and design, and transceiver
parametric evaluation for factory or field qualification.
For example, temperature per module can be observed in
high density applications to facilitate thermal evaluation
of blades, PCI cards and systems.
Required Host Board Components
The MSA power supply noise rejection filter is required on
the host PCB to meet data sheet performance. The MSA
filter incorporates an inductor which should be rated 400
mADC and 1 series resistance or better. It should not
be replaced with a ferrite. The required filter is illustrated
in Figure 4.
The MSA also specifies that 4.7 K to 10 K pull-up resis-
tors for TX_FAULT, LOS, and MOD_DEF0,1,2 are required
on the host PCB.

Fiber Compatibility
The AFBR-571xZ transciever is capable of transmission
at 2 to 550 meters with 50/125 µm fiber, and at 2 to 275
meters with 62.5 125 µm fiber, for 1.25 GBd Ethernet. It
is capable of transmission up to 500m with 50/125 µm
fiber and up to 300m with 62.5/125 µm fiber, for 1.0625
GBd Fiber Channel.
Application Support
To assist in the transceiver evaluation process, Agilent
offers a 1.25 Gbd Gigabit Ethernet evaluation board
which facilitates testing of the AFBR-571xZ. It can be
obtained through the Agilent Field Organization by ref-
erencing Agilent part number HFBR-0571.
A Reference Design including the AFBR-571xZ and the
HDMP-1687 GigaBit Quad SerDes is available. It may be
obtained through the Agilent Field Sales organization.
Regulatory Compliance
See Table 1 for transceiver Regulatory Compliance. Certi-
fication level is dependent on the overall configuration
of the host equipment. The transceiver performance is
offered as a figure of merit to assist the designer.
Electrostatic Discharge (ESD)
The AFBR-571xZ exceeds typical industry standards and is
compatible with ESD levels found in typical manufactur-
ing and operating environments as described in Table 1.
There are two design cases in which immunity to ESD
damage is important.
The first case is during handling of the transceiver prior
to insertion into the transceiver port. To protect the trans-
ceiver, its important to use normal ESD handling precau-
tions. These precautions include using grounded wrist
straps, work benches, and floor mats in ESD controlled
areas. The ESD sensitivity of the AFBR-571xZ is compat-
ible with typical industry production environments.
The second case to consider is static discharges to the
exterior of the host equipment chassis after installation.
To the extent that the optical interface is exposed to the
outside of the host equipment chassis, it may be subject
to system-level ESD requirements.
Electromagnetic Interference (EMI)
Equipment using the AFBR-571xZ family of transceivers
is typically required to meet the require ments 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 AFBR-
571xZ minimize the EMI challenge facing the host equip-
ment designer.
EMI Immunity
Equipment hosting AFBR-571xZ modules will be sub-
jected to radio-frequency electromagnetic fields in some
environments. The transceiver has excellent immunity to
such fields due to its shielded design.
Flammability
The AFBR-571xZ transceiver is made of metal and high
strength, heat resistant, chemically resistant, and UL
94V-0 flame retardant plastic.
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 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 operatio0n. 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.
