Module Package
Installation
The transceiver meets the Small
Form Pluggable (SFP) industry
standard package utilizing an
integral LC-Duplex optical
interface connector. The hotpluggable capability of the SFP
package allows the module to be
installed at any time – even with
the host system operating and online. This allows for system
configuration changes or
maintenance without system
down time. The HFBR-5720AL/
ALP uses a reliable 850 nm
VCSEL source and requires a 3.3
V DC power supply for optimal
design.
The HFBR-5720AL/ALP 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
module 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
connector in that order. This
printed circuit board card-edge
connector is depicted in Figure 2.
Serial Identification (EEPROM)
The HFBR-5720AL/ALP complies
with an industry standard MSA
that defines the serial
identification protocol. This
protocol uses the 2-wire serial
CMOS E2PROM protocol of the
ATMEL AT24C01A or equivalent.
The contents of the HFBR5720AL/ALP serial ID memory
are defined in Table 10 as
specified in the SFP MSA.

Figure 1 illustrates the major
functional components of the

Transmitter Section
The transmitter section includes
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
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 provided the data pattern is
valid 8B/10B balanced code.
the module as depicted in
Figure 6. The Tx Disable control
should be actuated upon
initialization of the module.
Tx Fault
The HFBR-5720AL/ALP 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 conditions. A fault is
cleared by cycling the Tx Disable
control input.
Tx Disable
The HFBR-5720AL/ALP 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
3
Receiver Section
The receiver section includes the
receiver optical subassembly
(ROSA) and 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 is mated to a custom IC
that provides 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
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.
The Loss of Signal (LOS) output
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
indicates 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., disconnected or broken
fiber connection to receiver,
failed transmitter).
Electrostatic Discharge (ESD)
Evaluation Kit
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
transceiver port. 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 HFBR5720AL/ALP 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 HFBR5720AL/ALP exceeds typical
industry standards.
To help you in your preliminary
transceiver evaluation, Agilent
offers a 2.125 GBd Fibre Channel
evaluation board. This board will
allow testing of the fiber-optic
VCSEL transceiver. Please
contact your local field sales
representative for availability and
ordering details.
Functional Data I/O
Agilent’s HFBR-5720AL/ALP
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-5720AL/ALP.
Reference Designs
Reference designs for the HFBR5720AL/ALP fiber-optic
transceiver and the HDMP-2630/
2631 physical layer IC are
available to assist the equipment
designer. Figure 4 depicts a
typical application configuration,
while Figure 5 depicts the MSA
power supply filter circuit design.
All artwork is available at the
Agilent Website. Please contact
your local field sales engineer for
more information regarding
application tools.
Caution should be taken for the
proper interconnection between
the supporting Physical Layer
integrated circuits and the HFBR5720AL/ALP. Figure 4 illustrates
the recommended interface
circuit.

Immunity
Flammability
Equipment hosting the HFBR5720AL/ALP modules will be
subjected to radio-frequency
electro-magnetic fields in some
environments. These transceivers
have good immunity to such
fields due to their shielded
design.
The HFBR-5720AL/ALP VCSEL
transceiver housing is made of
metal and high strength, heat
resistant, chemically resistant,
and UL 94V-0 flame retardant
plastic.
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-5720AL/ALP
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
perfornmance.
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 under normal operating
conditions and under a single
fault condition.

Caution
There are no user serviceable
parts nor any maintenance
required for the HFBR-5720AL/
ALP. Tampering with or
modifying the performance of the
HFBR-5720AL/ALP will result in
voided product warranty. It may
also result in improper operation
of the HFBR-5720AL/ALP
circuitry, and possible overstress
of the laser source. Device
degradation or product failure
may result. Connection of the
HFBR-5720AL/ALP to a nonapproved optical source,
operating above the recommended absolute maximum conditions
or operating the HFBR-5720AL/
ALP 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 recertify and re-identify the laser
product under the provisions of
U.S. 21 CFR (Subchapter J) and
the TUV.

Notes:
1. Tx Fault is an open collector/drain output which should be pulled up externally with a 4.7 K – 10 KΩ resistor on the host board to a supply
< VCCT+0.3 V or V CCR+0.3 V. When high, this output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the
output will be pulled to < 0.8 V.
2. Tx disable input is used to shut down the laser output per the state table below. It is pulled up within the module with a 4.7 K – 10 KΩ resistor.
Low (0 – 0.8 V):
Transmitter On

3. Mod-Def 0,1,2. are the module definition pins. They should be pulled up with a 4.7 K – 10 KΩ resistor on the host board to a supply less than
VCC T+0.3 V or VCCR+0.3 V.
Mod-Def 0 is grounded by the module to indicate that the module is present
Mod-Def 1 is clock line of two wire serial interface for optional serial ID
Mod-Def 2 is data line of two wire serial interface for optional serial ID
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7 K – 10 KΩ resistor on the host board to a
supply < VCC T, R+0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defined by
the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V.
5. RD–/+: These are the differential receiver outputs. They are AC coupled 100 Ω differential lines which should be terminated with 100 Ω
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.
6. VCC R and VCCT are the receiver and transmitter power supplies. They are defined as 2.97 – 3.63 V at the SFP connector pin. The maximum supply
current is 200 mA and the associated in-rush current will typically be no more than 30 mA above steady state after 500 nanoseconds.
7. TD–/+: These are the differential transmitter inputs. They are AC coupled differential lines with 100 Ω differential termination inside the module.
The AC coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 400 – 2400 mV
(200 – 1200 mV single ended), though it is recommended that values between 500 and 1200 mV differential (250 – 600 mV single ended) be used
for best EMI performance. These levels are compatible with CML and LVPECL voltage swings.

1. Internally AC coupled and terminated (100 Ohm differential). These levels are compatible with CML and LVPECL voltage swings.
2. Internally AC coupled with an external 100 Ohm differential load termination.
3. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern.
4. Contributed RJ is calculated for 1 x 10–12 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.
5. 20%–80% Rise and Fall times measured with a 500 MHz signal utilizing a 1010 data pattern.
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 FC-PI Rev 11 specification ”6.3.3 MM
Jitter Budget“ section, 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. Our component 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 in the FC-PI MM jitter specification table.

Notes:
1. An OMA of 196 is approximately equal to an average power of –9 dBm assuming an Extinction Ratio of 9 dB.
2. An OMA of 156 is approximately equal to an average power of –10 dBm assuming an Extinction Ratio of 9 dB.
3. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern.
4. Contributed RJ is calculated for 1 x 10–12 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.
5. 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 FC-PI Rev 11 specification ”6.3.3 MM
Jitter Budget“ section, 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. Our component 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 in the FC-PI MM jitter specification table.

Notes:
1. An OMA of 49 µW is approximately equal to an average power of –15 dBm, and the OMA typical of 16 µW is approximately equal to an average
power of –20 dBm, assuming an Extinction Ratio of 9 dB. Sensitivity measurements are made at eye center with a BER = 10E–12.
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 loss of Signal circuitry responds to OMA (peak to peak) power,
not to average power.
