Module Package
Agilent offers the Pin Through
Hole package utilizing an integral
LC-Duplex optical interface
connector. The transceiver uses a
reliable 850 nm VCSEL source and
requires a 3.3 V DC power supply
for optimal system design.

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.
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 HFBR-
5921AL.
Caution should be taken to
account for the proper
interconnection between the
supporting Physical Layer
integrated circuits and the HFBR-
5921AL. Figure 3 illustrates the
recommended interface circuit.
Reference Designs
Figure 3 depicts a typical
application configuration, while
Figure 4 depicts the multisourced
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
