Overview
Agilent’s HFBR-5911L/AL
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
(1000BASE-SX), 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.
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).
The SFF package of the HFBR5911L/AL allows designers of
Gigabit Ethernet networking
equipment to maximize their use
of available board space. The
footprint of the HFBR-5911L/AL
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-5911L/AL trace keep-out
area is less than 10% as large as
that required by SFP
transceivers. For applications
not requiring hot-pluggability,
the HFBR-5911L/AL offers a
more space-efficient package
without the additional cost and
complexity imposed by
pluggable architecture.
Tx_Disable
The HFBR-5911L/AL 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.
Module Diagrams
The major functional components
of the HFBR-5911L/AL 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.
2
Host systems should allow a
10 ms interval between
successive assertions of this
control signal.
Eye Safety Circuit
The HFBR-5911L/AL 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
The HFBR-5911L/AL 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.
The HFBR-5911L/AL 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-5911L/AL 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-5911L/AL 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-5911L/AL complies
with all applicable 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-5911L/AL 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.
3
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.
EMI Immunity
Due to its shielded design, the
EMI immunity of the
HFBR-5911L/AL exceeds typical
industry standards.
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-5911L/AL’s
compliance to these standards is
detailed in Table 11.
The metal housing and shielded
design of the HFBR-5911L/AL
minimize the EMI challenge
facing the equipment designer.
Flammability
The HFBR-5911L/AL 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-5911L/
AL. All adjustments are made at
the factory before shipment.
Tampering with, modifying,
misusing or improperly handling
the HFBR-5911L/AL 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-5911L/
AL 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.
