Agilent HFBR-53A3VEM/HFBR-53A3VFM
3.3 V 1 x 9 Fiber Optic Transceivers
for Fibre Channel
Data Sheet
Description
The HFBR-53A3VEM/FM
transceivers from Agilent
Technologies allow the system
designer to implement a range of
solutions for multimode Fibre
Channel applications.
The overall Agilent transceiver
product consists of three sections:
the transmitter and receiver optical
subassemblies, an electrical
subassembly, and the package
housing which incorporates a
duplex SC connector receptacle.
Transmitter Section
The transmitter section of the
HFBR-53A3VEM/FM consists of an
850 nm Vertical Cavity Surface
Emitting Laser (VCSEL) in an
Optical Subassembly (OSA), which
mates to the fiber cable. The OSA is
driven by a custom, silicon bipolar
IC which converts differential PECL
compatible logic signals into an
analog laser diode drive current.
The high speed output lines are
internally ac-coupled and
differentially terminate with a 100
resistor.
Receiver Section
The receiver of the
HFBR-53A3VEM/FM includes a
GaAs PIN photo-diode mounted
together with a custom, silicon
bipolar transimpedance
preamplifier IC in an OSA. This
OSA is mated to a custom silicon
bipolar circuit that provides post-
amplification and quantization.
The post-amplifier also includes a
Signal Detect circuit which pro-
vides a TTL logic-high output
upon detection of a usable input
optical signal level. The high
speed output lines are internally
ac-coupled.

Package and Handling Instructions
Flammability
The HFBR-53A3VEM/FM
transceiver housing is made of
high strength, heat resistant,
chemically resistant, and UL
94V-0 flame retardant plastic.
Recommended Solder and Wash
Process
The HFBR-53A3VEM/FM is
compatible with industry-
standard wave or hand solder
processes.
Process Plug
This transceiver is supplied with
a process plug (HFBR-5000) for
protection of the optical ports
within the duplex SC connector
receptacle. This process plug
prevents contamination during
wave solder and aqueous rinse as
well as during handling, shipping,
and storage. It is made of a high-
temperature, molded sealing
material that can withstand 80 °C
and a rinse pressure of 110 lbs
per square inch.
Recommended Solder Fluxes
Solder fluxes used with the
HFBR-53A3VEM/FM should be
water-soluble, organic fluxes.
Recommended solder fluxes
include Lonco 3355-11 from
London Chemical West, Inc. of
Burbank, CA, and 100 Flux from
Alpha-Metals of Jersey City, NJ.
Recommended Cleaning/Degrading
Chemicals
Alcohols: methyl, isopropyl,
isobutyl.
Aliphatics: hexane, heptane.
Other: soap solution, naphtha.
Do not use partially halogenated
hydrocarbons such as 1,1.1
trichloroethane, ketones such as
MEK, acetone, chloroform, ethyl
acetate, methylene dichloride,
phenol, methylene chloride, or
N-methylpyrolldone. Also, Agilent
does not recommend the use of
cleaners that use halogenated
hydrocarbons because of their
potential environmental harm.
Regulatory Compliance
(See the Regulatory Compliance
Table for transceiver
performance)
The overall equipment design will
determine the certification level.
The transceiver performance is
offered as a figure of merit to
assist the designer in considering
their use in equipment designs.
Electrostatic Discharge (ESD)
There are two design cases in
which immunity to ESD damage
is important.
The first case is during handling
of the transceiver prior to
mounting it on the circuit board.
It is important to use normal ESD
handling precautions for ESD
sensitive devices. These pre-
cautions include using grounded
wrist straps, work benches, and
floor mats in ESD controlled
areas. The transceiver perform-
ance has been shown to provide
adequate performance in typical
industry production
environments.
The second case to consider is
static discharges to the exterior
of the equipment chassis
containing the transceiver parts.
To the extent that the duplex SC
connector receptacle is exposed
to the outside of the equipment
chassis it may be subject to
whatever system-level ESD test
criteria that the equipment is
intended to meet. The transceiver
performance is more robust than
typical industry equipment
requirements of today.
Electromagnetic Interference (EMI)
Most equipment designs utilizing
these high-speed transceivers
from Agilent will be required to
meet the requirements of FCC in
the United States, CENELEC
EN55022 (CISPR 22) in Europe
and VCCI in Japan. Refer to EMI
section (page 4) for more details.
Immunity
Equipment utilizing these
transceivers will be subject to
radio-frequency electromagnetic
fields in some environments.
These transceivers have good
immunity to such fields due to
their shielded design.
Eye Safety
These laser-based transceivers
are classified as AEL Class I (U.S.
21 CFR(J) and AEL Class 1 per
EN 60825-1 (+A11). They are
eye safe when used within the
data sheet limits per CDRH. They
are also eye safe under normal
operating conditions and under
all reasonably forseeable single
fault conditions per EN60825-1.
Agilent has tested the transceiver
design for compliance with the
requirements listed below under
normal operating conditions and
under single fault conditions
where applicable. TUV Rheinland
has granted certification to these
transceivers for laser eye safety
and use in EN 60950 and EN
60825-2 applications. Their
performance enables the
transceivers to be used without
concern for eye safety up to
maximum volts transmitter VCC.

APPLICATION SUPPORT
Optical Power Budget and Link
Penalties
The worst-case Optical Power
Budget (OPB) in dB for a fiber-
optic link is determined by the
difference between the minimum
transmitter output optical power
(dBm avg) and the lowest
receiver sensitivity (dBm avg).
This OPB provides the necessary
optical signal range to establish a
working fiber-optic link. The OPB
is allocated for the fiber-optic
cable length and the corre-
sponding link penalties. For
proper link performance, all
penalties that affect the link
performance must be accounted
for within the link optical power
budget.
Data Line Interconnections
Agilent’s HFBR-53A3VEM/FM
fiber-optic transceiver is designed
for compatible PECL signals. The
transmitter inputs are internally
ac-coupled to the laser driver
circuit from the transmitter input
pins (pins 7, 8). The transmitter
driver circuit for the laser light
source is an ac-coupled circuit.
This circuit regulates the output
optical power. The regulated light
output will maintain a constant
output optical power provided
the data pattern is reasonably
balanced in duty factor. If the
data duty factor has long, con-
tinuous state times (low or high
data duty factor), then the output
optical power will gradually
change its average output optical
power level to its pre-set value.
The receiver section is internally
ac-coupled between the pre-
amplifier and the post-amplifier
stages. The actual Data and Data-
bar outputs of the post-amplifier
are ac-coupled to their respective
output pins (pins 2, 3). Signal
Detect is a single-ended, TTL
output signal that is dc-coupled
to pin 4 of the module. Signal
Detect should not be ac-coupled
externally to the follow-on
circuits because of its infrequent
state changes.
Caution should be taken to
account for the proper intercon-
nection between the supporting
Physical Layer integrated circuits
and this HFBR-53A3VEM/FM
transceiver. Figure 3 illustrates a
recommended interface circuit
for interconnecting to a dc PECL
compatible fiber-optic
transceiver.
Eye Safety Circuit
For an optical transmitter device
to be eye-safe in the event of a
single fault failure, the transmit-
ter must either maintain normal,
eye-safe operation or be disabled.
In the HFBR-53A3VEM/FM there
are three key elements to the
laser driver safety circuitry: a
monitor diode, a window detector
circuit, and direct control of the
laser bias. The window detection
circuit monitors the average
optical power using the monitor
diode. If a fault occurs such that
the transmitter DC regulation
circuit cannot maintain the preset
bias conditions for the laser
emitter within ± 20%, the
transmitter will automatically be
disabled. Once this has occurred,
only an electrical power reset will
allow an attempted turn-on of the
transmitter.
Signal Detect
The Signal Detect circuit provides
a TTL low output signal when the
optical link is broken or when the
transmitter is off. The Signal
Detect threshold is set to
transition from a high to low state
between the minimum receiver
input optional power and –30 dBm
avg. input optical power
indicating a definite optical fault
(e.g., unplugged connector for the
receiver or transmitter, broken
fiber, or failed far-end transmitter
or data source). A Signal Detect
indicating a working link is
functional when receiving
encoded 8B/10B characters. The
Signal Detect does not detect
receiver data error or error-rate.
Data errors are determined by
signal processing following the
transceiver.
Electromagnetic Interference (EMI)
One of a circuit board designer’s
foremost concerns is the control
of electromagnetic emissions
from electronic equipment.
Success in controlling generated
Electromagnetic Interference
(EMI) enables the designer to
pass a governmental agency’s
EMI regulatory standard; and
more importantly, it reduces the
possibility of interference to
neighboring equipment. The EMI
performance of an enclosure
using these transceivers is
dependent on the chassis design.
Agilent encourages using
standard RF suppression
practices and avoiding poorly
EMI-sealed enclosures.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each
parameter in isolation, all other parameters having values within the recommended operating conditions. It should not
be assumed that limiting values of more than one parameter can be applied to the product at the same time. Exposure
to the absolute maximum ratings for extended periods can adversely affect device reliability.

Notes:
1. 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.
This Optical Extinction Ratio is expressed in decibels (dB) by the relationship 10log(Phigh avg/Plow avg).
2. These are 20-80% values and include the effect of a fourth order filter.
3. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 1). The characteristics include rise time, fall time, pulse
overshoot, pulse undershoot, and ringing, all of which are controlled to prevent excessive degradation of the receiver sensitivity.
4. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
5. Return loss is defined as the minimum attenuation (dB) of received optical power for energy reflected back into the optical fiber.
