Description
Avagos AFBR-57L5APZ optical transceiver supports high-
speed serial links over multimode optical  ber at signaling
rates up to 1.0625 Gb/s. Compliant with Small Form
Pluggable (SFP) Multi Source Agreement (MSA) mechani-
cal and electrical speci cations for LC Duplex transceiv-
ers, ANSI Fibre Channel FC-PI, FC-PI-2 and compliant with
IEEE 802.3 for gigabit applications. The part is electrically
interoperable with SFP conformant devices.
As an enhancement to the conventional SFP interface
de ned in SFF-8074i, the AFBR-57L5APZ is compliant to
SFF-8472 (digital diagnostic interface for optical trans-
ceivers). Using the 2-wire serial interface de ned in the
SFF-8472 MSA, the AFBR-57L5APZ provides real time tem-
perature, supply voltage, laser bias current, laser average
output power and received input power. This information
is in addition to conventional SFP base data. 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).

Installation
The AFBR-57L5APZ can be installed in any SFF-8074i
compliant Small Form Pluggable (SFP) port regardless of
host equipment operating status. The AFBR-57L5APZ is
hot-pluggable, allowing the module to be installed while
the host system is operating and on-line. Upon insertion,
the transceiver housing makes initial contact with the
host board SFP cage, mitigating potential damage due to
Electro-Static Discharge (ESD).
Digital Diagnostic Interface and Serial Identi cation
The 2-wire serial interface is based on ATMEL AT24C01A
series EEPROM protocol and signaling detail. Conventional
EEPROM memory, bytes 0-255 at memory address 0xA0,
is organized in compliance with SFF-8074i. New digital
diag nostic information, bytes 0-255 at memory address
0xA2, is compliant to SFF-8472. The new diagnostic in-
formation provides the opportunity for Predictive Failure
Identi cation, Com pliance Prediction, Fault Isolation and
Component Monitoring.
Predictive Failure Identi cation
The AFBR-57L5APZ predictive failure feature allows a host
to identify potential link problems before system perfor-
mance is impacted. Prior identi cation of link problems
enables a host to service an application via “fail over to
a redundant link or replace a suspect device, maintain-
ing 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 asso ciated
with observing 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 en-
vironmental requirements. AFBR-57L5APZ 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 pinpoint
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-57L5APZ real-time monitors of
Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power can be
used to assess local transceiver current operating condi-
tions. In addition, status  ags 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-57L5APZ real-time monitors of Tx_Bias, Tx_Power,
Vcc, Temperature and Rx_Power. Potential uses are as
debugging aids for system installation and design, and
transceiver parametric evaluation for factory or  eld qual-
i cation. For example, temperature per module can be
observed in high density applications to facilitate thermal
evaluation of blades, PCI cards and systems.

Transmitter Section
The transmitter section includes consists of the Transmit-
ter Optical SubAssembly (TOSA) and laser driver circuitry.
The TOSA, containing an 850 nm VCSEL (Vertical Cavity
Surface Emitting 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 uses the
incoming di erential high speed logic signal to modulate
the laser diode driver current. This Tx laser driver circuit
regulates the optical power at a constant level provided
the incoming data pattern is dc balanced (8B/10B code,
for example).
Transmit Disable (Tx_Disable)
The AFBR-57L5APZ 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 trans-
ceiver operation. In the event of a fault (e.g. eye safety circuit
activated), cycling this control signal resets the module as
depicted in Figure 4. An internal pull up resistor disables
the transceiver transmitter until the host pulls the input
low. Host systems should allow a 10 ms interval between
successive assertions of this control signal. Tx_Disable can
also be asserted via the two-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
operation.
Transmit Fault (Tx_Fault)
A catastrophic laser fault will activate the transmitter
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
transmitter fault condition can also be monitored via the
two-wire serial interface (address A2, byte 110, bit 2).
Eye Safety Circuit
The AFBR-57L5APZ provides Class 1 (single fault tolerant)
eye safety by design and has been tested for compliance
with the requirements listed in Table 1. The eye safety
circuit continuously monitors the optical output power
level and will disable the transmitter upon detecting an
unsafe condition beyond the scope of Class 1 certi cation.
Such unsafe conditions can be due to inputs from the host
board (Vcc  uctuation, unbalanced code) or a fault within
the transceiver.

Receiver Section
The receiver section includes the Receiver Optical Sub-
Assembly (ROSA) and the ampli cation/quantization
circuitry. The ROSA, containing a PIN photodiode and
custom transimpedance ampli er, is located at the optical
interface and mates with the LC optical connector. The
ROSA output is fed to a custom IC that provides post-
ampli cation and quantization.
Receiver Loss of Signal (Rx_LOS)
The post-ampli cation IC also 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
factory set so that a high output indicates a de nite optical
fault has occurred. Rx_LOS can also be monitored via the
two-wire serial interface (address A2h, byte 110, bit 1).
Functional Data I/O
The AFBR-57L5APZ interfaces with the host circuit board
through twenty I/O pins (SFP electrical connector) iden-
ti ed by function in Table 2. The board layout for this
interface is depicted in Figure 6.
The AFBR-57L5APZ high speed transmit and receive inter-
faces require SFP MSA compliant signal lines on the host
board. To simplify board requirements, biasing resistors
and ac coupling capacitors are incorporated into the
SFP transceiver module (per SFF-8074i) and hence are
not required 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).
Figure 2 depicts the recom mended interface circuit to
link the AFBR-57L5APZ to supporting physical layer ICs.
Timing for MSA compliant control signals implemented in
the transceiver are listed in Figure 4.

Caution
There are no user serviceable parts nor maintenance re-
quirements for the AFBR-57L5APZ. All mechanical adjust-
ments are made at the factory prior to shipment. Tampering
with, modifying, misusing or improperly handling the
AFBR-57L5APZ will void the product warranty. It may also
result in improper operation and possibly overstress the
laser source. Performance degrada tion or device failure
may result. Connection of the AFBR-57L5APZ to a light
source not compliant with ANSI FC-PI or IEEE 802.3 speci -
cations, operating above maximum operating conditions
or in a manner inconsistent with it’s design and function
may result in exposure to hazardous light radiation and
may constitute an act of modifying or manufacturing a
laser product. Persons performing such an act are required
by law to re-certify and re-identify the laser product under
the provisions of U.S. 21 CFR (Subchapter J) and TUV.

Regulatory Compliance
The AFBR-57L5APZ complies with all applicable laws
and regulations as detailed in Table 1. Certi cation level
is dependent on the overall con guration of the host
equipment. The transceiver performance is o ered as a
gure of merit to assist the designer.
Electrostatic Discharge (ESD)
The AFBR-57L5APZ is compatible with ESD levels found
in typical manufacturing and operating environments as
described in Table 1. In the normal handling and operation
of optical transceivers, ESD is of concern in two circum-
stances.
The  rst case is during handling of the transceiver prior to
insertion into an SFP compliant cage. To protect the device,
it’s important to use normal ESD handling pre-cautions.
These include use of grounded wrist straps, work-benches
and  oor wherever a transceiver is handled.
The second case to consider is static discharges to the
exterior of the host equipment chassis after installation.
If the optical interface is exposed to the exterior of host
equipment cabinet, the transceiver may be subject to
system level ESD requirements.

Notes:
1. TX_FAULT is an open collector/drain output, which must be pulled up with a 4.7 k – 10 k resistor on the host board. 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 is an input that is used to shut down the transmitter optical output. It is internally pulled up (within the transceiver) with a 6.8 k
resistor.
Low (0 – 0.8 V): Transmitter on
Between (0.8 V and 2.0 V): Unde ned
High (2.0 – Vcc max) or OPEN: Transmitter Disabled
3. The signals Mod-Def 0, 1, 2 designate the two wire serial interface pins. They must be pulled up with a 4.7 k – 10 k resistor on the host board.
Mod-Def 0 is grounded by the module to indicate the module is present
Mod-Def 1 is serial clock line (SCL) of two wire serial interface
Mod-Def 2 is serial data line (SDA) of two wire serial interface
4. RX_LOS (Rx Loss of Signal) is an open collector/drain output that must be pulled up with a 4.7 k – 10 k resistor on the host board. 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-/+ designate the di erential receiver outputs. They are AC coupled 100 di erential lines which should be terminated with 100 di erential
at the host SERDES input. AC coupling is done inside the transceiver and is not required on the host board. The voltage swing on these lines will be
between 600 and 1600 mV di erential (300 – 800 mV single ended) when properly terminated.
6. VccR and VccT are the receiver and transmitter power supplies. They are de ned at the SFP connector pin. The maximum supply current is 300 mA
and the associated in-rush current will typically be no more than 30 mA above steady state after 2 microseconds.
7. TD-/+ designate the di erential transmitter inputs. They are AC coupled di erential lines with 100 di erential termination inside the module.
The AC coupling is done inside the module and is not required on the host board. The inputs will accept di erential swings of 400 – 2400 mV (200
– 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.

3. 1.0625 Gb/s stressed receiver vertical eye closure penalty (ISI) min. is 0.96 dB for 50 m  ber and 2.18 dB for 62.5 m  ber. Stressed receiver DCD
component min. (at TX) is 80 ps.
4. These average power values are speci ed with an Extinction Ratio of 9 dB. The loss of signal circuitry responds to valid 8B/10B encoded peak to
peak input optical power, not average power.
