The HFBR-5730L uses a reliable
850 nm VCSEL source and
requires a 3.3 V DC power supply
for optimal system design.
Module Diagrams
Figure 1 illustrates the major
functional components of the
HFBR-5730L. The connection
diagram of the module is shown
in Figure 2. Figure 7 depicts the
external configuration and dimen-
sions of the module.
Installation
The HFBR-5730L can be installed
in or removed from any
MultiSource Agreement (MSA)
compliant Small Form Pluggable
port regardless of whether the
host equipment is operating or
not. The module is simply
inserted, electrical-interface first,
under finger-pressure. Controlled
hot-plugging is ensured by design
and by 3-stage pin sequencing at
the electrical interface. The mod-
ule housing makes initial contact
with the host board EMI shield
mitigating potential damage due
to Electro-Static Discharge
(ESD). The 3-stage pin contact
sequencing involves (1) Ground,
(2) Power, and then (3) Signal
pins, making contact with the
host board surface mount con-
nector in that order. This printed
circuit board card-edge connec-
tor is depicted in Figure 2.
Serial Identification (EEPROM)
The HFBR-5730L complies with
an industry standard MultiSource
Agreement that defines the serial
identification protocol. This pro-
tocol uses the 2-wire serial CMOS
E2PROM protocol of the ATMEL
AT24C01A or equivalent. The
contents of the HFBR-5730L
serial ID memory are defined in
Table 10 as specified in the
SFP MSA.

Transmitter Section
The transmitter section includes
the transmitter optical subassem-
bly (TOSA) and laser driver cir-
cuitry. 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 silicon IC,
which converts differential logic
signals into an analog laser diode
drive current. This Tx driver
circuit regulates the optical
power at a constant level pro-
vided the data pattern is valid
8B/10B DC balanced code.
Tx Disable
The HFBR-5730L accepts a trans-
mit 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
as depicted in Figure 6. The Tx
Disable control should be actu-
ated upon initialization of the
module.
Tx Fault
The HFBR-5730L module features
a transmit fault control signal
output which when high indicates
a laser transmit fault has occurred
and when low indicates normal
laser operation. A transmitter
fault condition can be caused by
deviations from the recommended
module operating conditions or
by violation of eye safety condi-
tions. A transient fault can be
cleared by cycling the Tx Disable
control input.
Eye Safety Circuit
For an optical transmitter device
to be eye-safe in the event of a
single fault failure, the transmit-
ter 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
The receiver section includes the
receiver optical subassembly
(ROSA) and amplification/quanti-
zation circuitry. The ROSA, con-
taining a PIN photodiode and
custom transimpedance pre-
amplifier, is located at the optical
interface and mates with the LC
optical connector. The ROSA is
mated to a custom IC that pro-
vides post-amplification and
quantization. This circuit also
includes a loss of signal (LOS)
detection circuit which provides
an open collector logic high
output in the absence of a usable
input optical signal level.
Loss of Signal
The Loss of Signal (LOS) output
signal indicates that the optical
input signal to the receiver does
not meet the minimum detectable
level for Fibre Channel compliant
signals. When LOS is high it indi-
cates loss of signal. When LOS is
low it indicates normal operation.
The Loss Of Signal thresholds are
set to indicate a definite optical
fault has occurred (e.g., discon-
nected or broken fiber connection
to receiver, failed transmitter).
Functional Data I/O
Agilent's HFBR-5730L 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 function-
ality of the transmitter bias resis-
tors and coupling capacitors
within the fiber optic module.
The transceiver is compatible
with an "AC-coupled" configura-
tion and is internally terminated.
Figure 1 depicts the functional
diagram of the HFBR 5730L.
Caution should be taken to ac-
count for the proper interconnec-
tion between the supporting
physical layer integrated circuits
and the HFBR-5730L. Figure 4
illustrates the recommended in-
terface circuit.
Several MSA compliant control
data signals are implemented in
the module and are depicted in
Figure 6.

Regulatory Compliance
See Table 1 for transceiver Regu-
latory 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 insertion into the trans-
ceiver port. To protect the trans-
ceiver, it is important to use
normal ESD handling precau-
tions. These precautions include
using grounded wrist straps,
work benches, and floor mats in
ESD controlled areas. The ESD
sensitivity of the HFBR-5730L is
compatible with typical industry
production environments. The
second condition is static dis-
charges to the exterior of the
host equipment chassis after in-
stallation. 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 perfor-
mance of the HFBR-5730L ex-
ceeds typical industry standards.
Immunity
Equipment hosting the HFBR-
5730L modules will be subjected
to radio-frequency electromag-
netic fields in some environments.
The transceivers have good im-
munity 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 require-
ments 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-5730L mini-
mize the EMI challenge facing the
host equipment designer. These
transceivers provide superior
EMI performance. This greatly
assists the designer in the man-
agement of the overall system
EMI performance.
Eye Safety
These 850 nm VCSEL-based
transceivers provide Class 1 eye
safety by design. Agilent Tech-
nologies has tested the trans-
ceiver design for compliance with
the requirements listed in Table 1:
Regulatory Compliance, under
normal operating conditions and
under a single-fault condition.
Flammability
The HFBR-5730L VCSEL trans-
ceiver 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 any maintenance
required for the HFBR-5730L.
Tampering with or modifying the
performance of the HFBR-5730L
will result in voided product
warranty. It may also result in
improper operation of the
HFBR-5730L circuitry, and
possible overstress of the laser
source. Device degradation or
product failure may result. Con-
nection of the HFBR-5730L to a
non-approved optical source,
operating above the recommended
absolute maximum conditions or
operating the HFBR-5730L in a
manner inconsistent with its de-
sign and function may result in
hazardous radiation exposure and
may be considered an act of modi-
fying 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.
