RoHS-Compliant Optical Transceiver
Data Sheet
Description
Features
Avago Technologies’ AFBR-59R5LZ optical transceiver
supports high-speed serial links over multimode optical
fiber at signaling rates up to 4.25 GBd. Compliant with
the Small Form Factor (SFF) Multi Source Agreement
(MSA) 2x5/2x10 mechanical specifications for LC Duplex
transceivers, ANSI Fibre Channel FC-PI and IEEE 802.3 for
gigabit applications the part is electrically interoperable
with 2x5 and 2x6 conformant devices. The AFBR-59R5LZ
is dimensionally compliant with the SFF MSA form factor
with the exception of two additional pins for communicating with the diagnostic interface.
• Fully RoHS Compliant
As an enhancement to the conventional SFF 2x5 interface
defined in the SFF MSA (Multi-Source Agreement), the
AFBR-59R5LZ is compliant to SFF-8472 (digital diagnostic
interface for optical transceivers). Using the 2-wire serial
interface defined in the SFF-8472 MSA, the AFBR-59R5LZ
provides real time temperature, supply voltage, laser bias
current, laser average output power and received average
input power.
This information is in addition to conventional SFP/GBIC
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 Signal Detect (Sig_Det). This 2x7 package also
includes one dedicated ‘hard’ pin for TX_FAULT.

Digital Diagnostic Interface and Serial Identification
Compliance Prediction:
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 diagnostic information, bytes 0-255 at memory
address 0xA2, is compliant to SFF-8472. The new diagnostic information provides the opportunity for Predictive Failure Identification, Compliance Prediction, Fault
Isolation and Component Monitoring.
Compliance prediction is the ability to determine if an
optical transceiver is operating within its operating and
environmental requirements. AFBR-59R5LZ 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.
The I2C accessible memory page address 0xB0 is used
internally by SFP for the test and diagnostic purposes
and it is reserved.
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 redundant link or replace a suspect device, maintaining system
uptime in the process. For applications where ultra-high
system uptime is required, a digital SFF provides a means
to monitor two real-time laser metrics associated with
observing laser degradation and predicting failure: average laser bias current (Tx_Bias) and average laser optical
power (Tx_Power).
Fault Isolation
The fault isolation feature allows a host to quickly pinpoint the location of a link failure, minimizing system
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-59R5LZ realtime monitors of Tx_Bias, Tx_Power, Vcc, Temp and Rx
average power can be used to assess local transceiver
current operating conditions. In addition, status flags Tx
Disable and Rx Signal Detect are mirrored in memory and
available via the two-wire serial interface.

Component Monitoring
Eye Safety Circuit
The AFBR-59R5LZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temp and Rx Average Power may potentially be
used as a debugging aid 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 and systems.
The AFBR-59R5LZ 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 optical output power levels
and will disable the transmitter upon detecting an unsafe condition beyond the scope of Class 1 certification.
Such unsafe conditions can be due to inputs from the
host board (Vcc fluctuation, unbalanced code) or a fault
within the transceiver.
Transmitter Section
The transmitter section contains 850nm VCSEL (Vertical
Cavity Surface Emitting Laser) light source, located at the
optical interface which mates with the LC optical connector. The VCSEL is driven by a custom IC which uses
the incoming differential (PECL compatible) high speed
logic signal to modulate laser diode driver current. This
Tx laser driver circuit regulates optical output power at a
constant level provided the incoming data pattern is dc
balanced (8B/10B code, for example).
Receiver Section
Transmit Disable (Tx_Disable)
The post-amplification IC also includes the transition
detection circuitry which monitors the ac level of incoming optical signals and provides a TTL status signal to the
host. An adequate optical input results in high signal
detect output while a low signal detect output indicates
an unusable optical input. The signal detect thresholds
are set so that a low output indicates a definite optical
fault has occurred. Signal Detect can be monitored via
the two-wire serial (address A2h, byte 110, bit 1).
The AFBR-59R5LZ accepts a TTL transmit disable control
signal input which shuts down the transmitter. A high
signal implements 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 5. An internal
pull down resistor enables the laser if the line is not connected on the host board. Host systems should allow
a 10ms interval between successive assertions of this
control signal. Tx_Disable can be asserted via the twowire 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 the
TX_DISABLE pin to control the transmit output.

The receiver section contains a PIN photodiode and custom transimpedance preamplifier, located at the optical
interface which mates with the LC optical connector. The
output is fed to a custom IC that provides post-amplification and quantization.
Signal Detect (Sig_Det)
Functional Data I/O
Caution
The AFBR-59R5LZ interfaces with the host circuit board
through fourteen I/O pins (2x7) identified by function
in Table 2. These pins are sized for the use in boards between 0.062 in. and 0.100 in. thick. The board layout for
this interface is depicted in Figure 7.
There are no user serviceable parts nor maintenance
requirements for the AFBR-59R5LZ. All mechanical
adjustments are made at the factory before shipping.
Tampering with, modifying, misusing or improperly handling the AFBR-59R5LZ will void the product warranty.
It may also result in improper operation and possibly
overstress the laser source. Performance degradation
or device failure may result. Connection of the AFBR59R5LZ to a light source not compliant to IEEE 802.3 or
ANSI FC-PI specifications, operating above the 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.
The AFBR-59R5LZ transmit and receive interfaces are
PECL compatible. To simplify board requirements,
transmitter bias resistors and ac coupling capacitors are
incorporated into the transceiver module and so are not
required on the host board. The Tx_Disable and Signal
Detect lines require TTL lines on the host board if they
are to be utilized. The transceiver will operate normally if
these lines are not connected on the host board.
Figure 2 depicts the recommended interface circuit to
link the AFBR-59R5LZ to the supporting physical layer
ICs. Timing for MSA compliant control signals implemented in the transceiver are listed on Page 12 and
diagramed in Figure 5.
PCB Assembly Process Compatibility
The AFBR-59R5LZ is compatible with industry standard
wave solder and aqueous wash processes as detailed on
Page 13. The transceiver is shipped with a process plug
to keep out impinging liquids, but is not intended to be
immersed. After assembly, the process plug should be
kept in place as a dust plug when the transceiver is not
in use.

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 the TUV.

Regulatory Compliance
The AFBR-59R5LZ complies with all applicable laws and
regulations as detailed in Table 1. Certification 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-59R5LZ 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
circumstances.
If the optical interface is exposed to the exterior of host
equipment cabinet, the transceiver may be subject to
system level ESD requirements.
Electromagnetic Interference (EMI)
Equipment incorporating gigabit transceivers is typically
subject to regulation by the FCC in the United States, TUV
and CENELEC EN55022 (CISPR 22) in the European Union
and VCCI in Japan. The AFBR-59R5LZ’s compliance to
these standards is detailed in Table 1. The metal housing
and shielded design of the AFBR-59R5LZ minimize the
EMI challenge facing the equipment designer.
Flammability
The first case is during handling of the transceiver prior
to soldering onto the host board. To protect the device,
it’s important to use normal ESD handling precautions.
These include using grounded wrist straps, workbenches
and floor mats wherever the transceiver is handled.
The AFBR-59R5LZ optical transceiver is made of metal
and high strength, heat resistant, chemical resistant and
UL 94V-0 flame retardant plastic.
The second case to consider is static discharges to the
exterior of the host equipment chassis after assembly.
Due to its shielded design, the EMI immunity of the
AFBR-59R5LZ exceeds typical industry standards.

Notes:
1. TX_DISABLE is an input that is used to shut down the transmitter optical output. It is pulled down with 6.8 kW internal to the transceiver.
Low (0 – 0.8 V) or Open: Transmitter Enabled
Between (0.8 V and 2.0 V): Undefined
High (2.0 – VCC max): Transmitter Disabled
The TX_DISABLE pin state is logic Or’d with the contents of EEPROM address A2h, byte 110 bit 6 (soft disable control bit) to control the transmit output.
2. The signals SDA and SCL designate the two wire serial interface pins. They must be pulled up with a 4.7 k – 10 kW resistor on the host board.
SCL is the serial clock line of two wire serial interface. SDA is the serial data line of two wire serial interface
3. Signal Detect is a normally high LVTTL output. When high it indicates the received optical power is adequate for normal operation. When
Low, it indicates the received optical power is insufficient to guarantee error free operation. In the low state, the output will be pulled to <
0.8 V.
4. RD-/+ designate the differential receiver outputs. They are ac coupled 100 W differential lines which should be terminated with 100 W differential 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 differential (300 – 800 mV single ended) when properly terminated.
5. VCCR and VCCT are the receiver and transmitter power supplies. They are defined at the transceiver pins.
6. TD-/+ designate the differential transmitter inputs. They are ac coupled differential lines with 100 W differential termination inside the module. The ac coupling is done inside the module and is not required on the host board. The inputs will accept differential swings of 400 – 2400
mV (200 – 1200 mV single ended), though it is recommended that values between 500 and 1200 mV differential (250 – 600 mV single ended)
be used for best EMI performance.
7. Transmitter and Receiver Ground are common internally on the transceiver PCB. They are electrically connected to signal ground within the
transceiver.
8. TX_FAULT is an open collector/drain output, which must be pulled up with a 4.7k – 10kW 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 < 0.8V.
