Overview
Tx_Disable
Avago Technologies’ HFBR-5911LZ/ALZ optical transceiver
supports high-speed serial links over multimode optical
fiber at signaling rates of up to 1.25 Gb/s. Compliant
with the Small Form Factor (SFF) Multi Source Agreement
(MSA) for 2 x 5 pin LC Duplex transceivers and IEEE 802.3
specification for Gigabit Ethernet (GbE) links (1000BASESX), the part is interoperable and interchangeable with
other conformant devices. Supported Gigabit Ethernet
link lengths are described in Table 1, but the transceiver
can also be used for other high-speed serial applications,
such as iSCSI.
The HFBR-5911LZ/ALZ 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 page 12.
A pull-down resistor enables the laser if the line is not
connected on the host board.
The SFF package of the HFBR-5911LZ/ALZ allows designers of Gigabit Ethernet networking equipment to maximize their use of available board space. The footprint
of the HFBR-5911LZ/ALZ is significantly smaller than
those of other GbE transceivers formats - 25% smaller
than SFP cage assemblies, 30% smaller than traditional
1 x 9 transceivers and 70% smaller than GBIC rail assemblies. The HFBR-5911LZ/ALZ trace keep-out area is
less than 10% as large as that required by SFP transceivers. For applications not requiring hot-pluggability, the
HFBR-5911LZ/ALZ offers a more space-efficient package
without the additional cost and complexity imposed by
pluggable architecture.
Eye Safety Circuit
Module Diagrams
The major functional components of the HFBR-5911LZ/ALZ
are illustrated in Figure 2 page 9. The external configuration of the transceiver is depicted in Figure 3 page 10
while the host board and front panel layouts defined by
the SFF MSA are shown in Figure 4, page 11.
Transmitter Section
The transmitter section consists of the Transmitter 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 differential PECL logic
signals to modulate the laser diode drive current. This Tx laser
driver circuit regulates the optical output power at a constant
level provided that the incoming data pattern is dc balanced
(8B10B code for example).
2
Host systems should allow a 10 ms interval between successive assertions of this control signal.
The HFBR-5911LZ/ALZ provides Class 1 eye safety by
design and has been tested for compliance with the
requirements listed in Table 11. The eye safety circuit
continuously monitors optical output power levels and
will disable the transmitter upon detecting an unsafe
condition. Such unsafe conditions can be due to inputs
from the host board (VCC fluctuation, unbalanced code)
or faults within the transceiver.
Receiver Section
The receiver section includes the Receiver Optical Subassembly (ROSA) and the amplification/quantization circuitry. The
ROSA, containing a PIN photodiode and custom transimpedance preamplifier, 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-amplification and quantization.
Signal Detect
The post-amplification/quantizer IC also includes transition
detection circuitry that monitors the ac level of the incoming
optical signal and provides a TTL status signal to the host. An
adequate optical input results in a high 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 (e.g., disconnected or
broken fiber connection to receiver, failed transmitter, etc.).
Electrical Interfaces
EMI Immunity
The HFBR-5911LZ/ALZ interfaces with the host circuit
board through the ten I/O pins identified by function in
Table 4. These pins are sized for use in boards between
0.062 in. and 0.100 in. thick. The board layout for this
interface is depicted in Figure 4. Due to its shielded design, the EMI immunity of the HFBR5911LZ/ALZ exceeds typical industry standards.
The HFBR-5911LZ/ALZ transmit and receive interfaces
require PECL differential signal lines on the host board. 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 a recommended interface circuit to link the
HFBR-5911LZ/ALZ to the supporting physical layer ICs.
Timing for the MSA compliant control signals implemented in this transceiver are listed in Table 9 and diagramed
in Figure 5.
PCB Assembly Process Compatibility
The HFBR-5911LZ/ALZ is compatible with industrystandard wave solder and aqueous wash processes as
detailed in Table 10. 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.
Regulatory Compliance
The HFBR-5911LZ/ALZ complies with all ap plicable laws and regulations as detailed in
Table 11. Certification level is dependent of 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 HFBR-5911LZ/ALZ is compatible with ESD levels found
in typical manufacturing and operating environments as described in Table 11. In the normal handling and operation of
optical transceivers, ESD is of concern in two circumstances.
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 second case to consider is static discharges to the exterior
of the host equipment chassis after assembly. If the optical
interface is exposed to the exterior of the host equipment
cabinet, the transceiver may be subject to system-level ESD
requirements.
3
Electromagnetic Interference (EMI)
Equipment incorporating Gigabit transceivers is typically subject to regulation by the FCC in the United States, TUV in the
European Union and VCCI in Japan. The HFBR-5911LZ/ALZ’s
compliance to these standards is detailed in Table 11.
The metal housing and shielded design of the HFBR5911LZ/ALZ minimize the EMI challenge facing the
equipment designer.
Flammability
The HFBR-5911LZ/ALZ optical transceiver is made of metal
and high strength, heat resistant, chemical resistant and
UL 94V-0 flame retardant plastic.
Caution
There are no user serviceable parts nor any maintenance
required for the HFBR-5911LZ/ALZ. All adjustments are
made at the factory before shipment. Tampering with,
modifying, misusing or improperly handling the HFBR5911LZ/ALZ 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 HFBR-5911LZ/ALZ to a
light source not compliant to the Gigabit Ethernet specification (IEEE 802.3), operating above the recommended
absolute maximum operating conditions or in a manner
inconsistent with it’s design and function may result in
exposure to hazardous radiation and may constitute
an act of modifying or manufacturing a laser product.
Person’s performing such an act are required by law to
recertify and re-identify the laser product under the provisions of U.S. 21 CFR (Subchapter J).

Notes:
11. The maximum Optical Output Power complies with IEEE 802.3 and is Class 1 laser eye safe.
12. Optical Extinction Ratio is defined as the ratio of the average optical power of the transmitter in the high (“1”) state to the low (“0”) state. The
transmitter is driven with a Gigabit Ethernet 1250 MBd 8b/10b encoded serial data pattern. Optical Extinction Ratio is expressed in decibels
(dB) by the relationship 10log(Phigh avg/Plow avg).
13. Optical Rise and Fall Times are 20-80% value. Laser transmitter pulse characteristics are typically specified by an eye diagram - see Figure 6. The characteristics include rise time, fall time, pulse overshoot, pulse undershoot and ringing, all of which are controlled to prevent excessive
degradation of receiver sensitivity. These parameters are specified by the referenced Gigabit Ethernet eye diagram using the required filter.
The output optical waveform complies with the requirements of the eye mask described in IEEE 802.3 section 38.6.10 and Figure 38-2.
14. CPR is measured in accordance with EIA/TIA-526-14A as referenced in IEEE 802.3 section 38.6.10.
15. Measured at TP2. TP refers to the compliance point specified by IEEE 802.3, section 38.2.1.
16. Tested with a 100 mVP-P sinusoidal signal in the frequency range from 10 Hz to 2 MHz on the VCC supply with the recommended power supply filter (with C8) in place. Typically, a change in sensitivity of less than 1 dB is experienced.
