Solder and Wash Process Capability
These transceivers are delivered
with protective process plugs
inserted into the LC connector
receptacle. This process plug
protects the optical
subassemblies during wave solder
and aqueous wash processing and
acts as a dust cover during
shipping. These transceivers are
compatible with industry
Recommended Solder Fluxes
Solder fluxes used with the
HFBR-5921AL should be watersoluble, 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.

standard wave or hand solder
processes.
Recommended Cleaning/Degreasing
Chemicals
Alcohols: methyl, isopropyl,
isobutyl.
Aliphatics: hexane, heptane.
Other: naphtha.
Do not use partially halogenated
hydrocarbons such as 1,1.1
trichoroethane or 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.
Transmitter Section
The transmitter section includes
an 850 nm VCSEL (Vertical
Cavity Surface Emitting Laser)
light source and a transmitter
driver circuit. The driver circuit
maintains a constant optical
power level provided that the data
pattern is valid 8B/10B code.
Connection to the transmitter is
provided via an LC optical
connector.
TX Disable
The HFBR-5921AL accepts a
transmit disable control signal
input which shuts down the
transmitter. A high signal
implements this function while a
low signal allows normal laser
operation. In the event of a fault
(e.g., eye safety circuit activated),
cycling this control signal resets
the module. The TX Disable
control should be actuated upon
initialization of the module. See
Figure 5 for product timing
diagrams.
Eye Safety Circuit
For an optical transmitter device
to be eye-safe in the event of a
single fault failure, the transmitter
will either maintain normal,
eye-safe operation or be disabled.
In the event of an eye safety fault,
the VCSEL will be disabled.
Receiver Section
Connection to the receiver is
provided via an LC optical
connector. The receiver circuit
includes a Signal Detect (SD)
circuit which provides an open
collector logic low output in the
absence of a usable input optical
signal level.
3
Signal Detect
The Signal Detect (SD) output
indicates if the optical input
signal to the receiver does not
meet the minimum detectable
level for Fibre Channel compliant
signals. When SD is low it
indicates loss of signal. When SD
is high it indicates normal
operation. The Signal Detect
thresholds are set to indicate a
definite optical fault has occurred
(e.g., disconnected or broken
fiber connection to receiver, failed
transmitter).
Functional Data I/O
Agilent’s HFBR-5921AL fiber-optic
transceiver is designed to accept
industry standard differential
signals. In order to reduce the
number of passive components
required on the customer’s board,
Agilent has included the
functionality of the transmitter
bias resistors and coupling
capacitors within the fiber optic
module. The transceiver is
compatible with an “AC-coupled”
configuration and is internally
terminated. Figure 1 depicts the
functional diagram of the HFBR5921AL.
Caution should be taken to
account for the proper
interconnection between the
supporting Physical Layer
integrated circuits and the HFBR5921AL. Figure 3 illustrates the
recommended interface circuit.
Reference Designs

application configuration, while

power supply filter circuit design.
Regulatory Compliance
See Table 1 for transceiver
Regulatory Compliance
performance. The overall
equipment design will determine
the certification level. The
transceiver performance is
offered as a figure of merit to
assist the designer.
Electrostatic Discharge (ESD)
There are two conditions in which
immunity to ESD damage is
important. Table 1 documents our
immunity to both of these
conditions. The first condition is
during handling of the transceiver
prior to attachment to the PCB. To
protect the transceiver, it is
important to use normal ESD
handling precautions. These
precautions include using
grounded wrist straps, work
benches, and floor mats in ESD
controlled areas. The ESD
sensitivity of the HFBR-5921AL is
compatible with typical industry
production environments. The
second condition is static
discharges to the exterior of the
host equipment chassis after
installation. To the extent that the
duplex LC optical interface is
exposed to the outside of the host
equipment chassis, it may be
subject to
system-level ESD
requirements. The ESD
performance of the HFBR-5921AL
exceeds typical industry
standards.
Immunity
Equipment hosting the
HFBR-5921AL modules will be
subjected to radio-frequency
electromagnetic fields in some
environments. The transceivers
have good immunity to such fields
due to their shielded design.
Electromagnetic Interference (EMI)
Most equipment designs utilizing
these high-speed transceivers from
Agilent Technologies will be
required to meet the requirements
of FCC in the United States,
CENELEC EN55022 (CISPR 22) in
Europe and VCCI in Japan. The
metal housing and shielded design
of the HFBR-5921AL minimize the
EMI challenge facing the host
equipment designer. These
transceivers provide superior EMI
performance. This greatly assists
the designer in the management
of the overall system EMI
performance.
Eye Safety
These 850 nm VCSEL-based
transceivers provide Class 1 eye
safety by design. Agilent
Technologies has tested the
transceiver design for compliance
with the requirements listed in
Table 1: Regulatory Compliance,
under normal operating
conditions and under a single
fault condition.
Reliability
These transceivers have an
estimated failure rate of <100
FITS @ 50ºC.
Flammability
The HFBR-5921AL VCSEL
transceiver housing is made of
metal and high strength, heat
resistant, chemically resistant,
and UL 94V-0 flame retardant
plastic.
Caution
There are no user serviceable
parts nor is any maintenance
required for the HFBR-5921AL. All
adjustments are made at the
factory before shipment to our
customers. Tampering with or
modifying the performance of the
HFBR-5921AL will result in voided
product warranty. It may also
result in improper operation of
the HFBR-5921AL circuitry, and
possible overstress of the laser
source. Device degradation or
product failure may result.
Connection of the HFBR-5921AL
to a non-approved optical source,
operating above the
recommended absolute maximum
conditions or operating the HFBR5921AL in a manner inconsistent
with its design and function may
result in hazardous radiation
exposure and may be considered
an act of modifying or
manufacturing a laser product.
The person(s) performing such an
act is 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.

Notes:
1. Transmitter an d Receiver Ground are common in the internal module PCB. They are electrically connected to signal
ground within the module, and to the housing shield (see Note 5 in Figure 7c). This housing shield is electrically isolated
from the nose shield which is connected to chassis ground (see Note 4 in Figure 7c).
2. TX disable input is used to shut down the laser output per the state table below. It is pulled down internally within the
module with a 9.0 KW resistor.

3. SD (Signal Detect) is a normally high LVTTL output. When high it indicates that the received optical power is adequate
for normal operation. When Low, it indicates that the received optical power is below the worst case receiver sensitivity,
a fault has occurred, and the link is no longer valid.
4. RD-/+: These are the differential receiver outputs. They are AC coupled 100 W differential lines which should be
terminated with 100 W differential at the user SerDes. The AC coupling is done inside the module and is thus not
required on the host board. The voltage swing on these lines will be between 400 and 2000 mV differential (200 – 1000
mV single ended) when properly terminated. These levels are compatible with CML and LVPECL voltage swings.
5. VCCR and VCCT are the receiver and transmitter power supplies. They are defined as 2.97 – 3.63 V at the PTH connector
pin. The maximum supply current is 200 mA.

3. 20%-80% Rise and Fall times measured with a 500 MHz signal utilizing a 1010 data pattern.
4. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern.
5. Contributed RJ is calculated for 1E-12 BER by multiplying the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per the FC-PI standard (Table 13 - MM jitter output, note 1), the actual contributed RJ is allowed to increase above its
limit if the actual contributed DJ decreases below its limits, as long as the component output DJ and TJ remain within their specified FC-PI maximum limits with the worst case specified component jitter input.
6. In a network link, each component’s output jitter equals each component’s input jitter combined with each component’s contributed
jitter.
Contributed DJ adds in a linear fashion and contributed RJ adds in a RMS fashion. In the Fibre Channel specification, there is a
table specifying the input and output DJ and TJ for the receiver at each data rate. In that table, RJ is found from TJ –DJ, where the
RX input jitter is noted as Gamma R, and the RX output jitter is noted as Delta R. The HFBR-5921AL contributed jitter is such that,
if the maximum specified input jitter is present, and is combined with our maximum contributed jitter, then we meet the specified
maximum output jitter limits listed in the FC-PI MM jitter specification table.

Notes:
1. An OMA of 49 uW is approximately equal to an average power of -15dBm, and the OMA typical of 16 uW is approximately equal to an average
power of -20 dBm, assuming an Extinction Ratio of 9dB. Sensitivity measurements are made at eye center with BER = 1E-10.
2. An OMA of 31 is approximately equal to an average power of –17 dBm assuming an Extinction Ratio of 9 dB.
3. 2.125 Gb/s Stressed receiver vertical eye closure penalty (ISI) min. is 1.26 dB for 50 µm fiber and 2.03 dB for 62.5 µm fiber. Stressed receiver DCD
component min. (at TX) is 40 ps.
4. 1.0625 Gb/s Stressed receiver vertical eye closure penalty (ISI) min. is 0.96 dB for 50 µm fiber and 2.18 dB for 62.5 µm fiber. Stressed receiver
DCD component min. (at TX) is 80 ps.
5. These average power values are specified with an Extinction Ratio of 9 dB. The Signal Detect circuitry responds to OMA (peak-to-peak) power,
not to average power.
6. Please refer to the HFBR-5921AL Characterization Report for typical values.
