Overview
The HFBR-5701L offers maximum flexibility to designers,
manufacturers, and operators of
Gigabit Ethernet networking
equipment. A pluggable architecture allows the module to be
installed into MSA standard SFP
ports at any time – even with the
host equipment operating and
online. This facilitates the rapid
configuration of equipment to
precisely the user’s needs –
reducing inventory costs and
network downtime. Compared
with traditional transceivers, the
size of the Small Form Factor
package enables higher port
densities.
Module Diagrams
Figure 1 illustrates the major
functional components of the
HFBR-5701L. The external
configuration of the module is
depicted in Figure 7. Figure 8
depicts the panel and host board
footprints.
Installation
The HFBR-5701L can be installed
in or removed from any MSAcompliant Pluggable Small Form
2
Factor 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
3-stage pin sequencing at the
electrical interface. This printed
circuit board card-edge connector
is depicted in Figure 2.
As the HFBR-5701L is inserted,
first contact is made by the
housing ground shield,
discharging any potentially
component-damaging static
electricity. Ground pins engage
next and are followed by Tx and
Rx power supplies. Finally, signal
lines are connected. Pin functions
and sequencing are listed in
Table 2.

TOP OF BOARD
Figure 2. Pin description of the SFP electrical interface.
BOTTOM OF BOARD
(AS VIEWED THROUGH TOP OF BOARD)
Before extracting the module, the
black plastic tab beneath the
optical port must be depressed,
releasing the latch mechanism.
The transceiver can then be
pulled out of the port manually by
gripping the side of the LC ports.
For easier fingertip delatching in
high port density applications, an
optional extended tab is offered
as shown in Figure 10.
Serial Identification (EEPROM)
The HFBR-5701L features an
EEPROM for Serial ID. It
contains the product data stored
for retrieval by host equipment.
This data is accessed via the 2wire serial EEPROM protocol of
the ATMEL AT24C01A or similar
in compliance with the industry
standard SFP Multi-Source
Agreement. Contents of the
HFBR-5701L serial ID memory
are displayed in Table 9.
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 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 DC
balanced (8B10B code for
example).
Tx Disable
The HFBR-5701L 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
3
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.
Eye Safety Circuit
The HFBR-5701L provides Class
1 eye safety by design and has
been tested for compliance with
the requirements listed in
Table 1. The eye safety circuit
continuously monitors optical
output power levels and will
disable the transmitter and assert
a TX_FAULT signal upon
detecting an unsafe condition.
Such unsafe conditions can be
created by inputs from the host
board (Vcc fluxuation,
unbalanced code) or faults within
the module.
Receiver Section
The receiver section includes the
Receiver Optical Subassembly
(ROSA) and amplification/
quantization circuitry. The ROSA,
containing a PIN photodiode and
custom trans-impedance
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. Also included is
a Loss Of Signal (LOS) detection
circuit.
Loss of Signal
The Loss Of Signal (LOS) output
indicates an unusable optical
input power level. A high LOS
output signal indicates a loss of
signal while a low LOS output
signal 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, etc.).
Functional I/O
The HFBR-5701L accepts
industry standard differential
signals such as LVPECL and CML
within the scope of the SFP MSA.
To simplify board requirements,
transmitter bias resistors and
coupling capacitors are
incorporated into the transceiver
module. The module is “accoupled” and internally
terminated.
Figure 4 illustrates a recommended interface circuit to link
the HFBR-5701L to the
supporting Physical Layer
integrated circuits.
Timing diagrams for the MSA
compliant control signals
implemented in this module are
depicted in Figure 6.

Required Host Board Components
The MSA power supply noise
rejection filter is required on the
host PCB to meet data sheet
performance. The MSA filter
incorporates an inductor which
should be rated 400 mADC and
1 Ω series resistance or better. It
should not be replaced with a
ferrite. The required filter is
illustrated in Figure 3.
The MSA also specifies that 4.7 K
to 10 KΩ pull-up resistors for
TX_FAULT, LOS, and
MOD_DEF0,1,2 are required on
the host PCB.
Application Support
Evaluation Kit
To assist in the transceiver
evaluation process, Agilent offers
a 1.25 Gbd Gigabit Ethernet
evaluation board which facilitates
testing of the HFBR-5701L. It can
be obtained through the Agilent
Field Organization by referencing
Agilent part number HFBR-0571.
Reference Designs
A Reference Design including the
HFBR-5701L and the HDMP1687 GigaBit Quad SerDes is
available. It may be obtained
through the Agilent Field Sales
organization.
Regulatory Compliance
See Table 1 for transceiver
Regulatory Compliance. Certification level is dependent on the
overall configuration of the host
equipment. The transceiver
performance is offered as a figure
of merit to assist the designer.
4
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
insertion into the transceiver
port. To protect the transceiver,
it’s 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-5701L is
compatible with typical industry
production environments.
The second case to consider is
static discharges to the exterior
of the host equipment chassis
after installation. To the extent
that the optical interface is
exposed to the outside of the host
equipment chassis, it may be
subject to system-level ESD
requirements.
Immunity
The ESD performance of the
HFBR-5701L exceeds typical
industry standards.
Equipment hosting HFBR-5701L
modules will be subjected to
radio-frequency electromagnetic
fields in some environments. The
transceiver has good immunity to
such fields due to its shielded
design.
Electromagnetic Interference (EMI)
Equipment incorporating Gigabit
Ethernet transceivers is typically
required to meet the requirements of the FCC in the United
States, CENELEC EN55022
(CISPR 22) in Europe, and VCCI
in Japan.
The metal housing and shielded
design of the HFBR-5701L
minimize the EMI challenge
facing the host equipment
designer.
Flammability
The HFBR-5701L transceiver 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-5701L. All
adjustments are made at the
factory before shipment to our
customers. Tampering with,
modifying, misusing or improperly handling the HFBR-5701L
will void the product warranty. It
may also result in improper
operation of the HFBR-5701L
circuitry, and possible overstress
of the laser source. Device
degradation or Product failure
may result. Connection of the
HFBR-5701L to a non-Gigabit
Ethernet-compliant optical
source, operating above the
recommended absolute maximum
conditions or operating the
HFBR-5701L 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).

Notes:
1. TX Fault is an open collector/drain output which should be pulled up externally with a 4.7K – 10 KΩ resistor on the host board to a supply < VccT+0.3 V
or VccR+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 4.7-10 K resistor.
Low (0 – 0.8 V):
Transmitter on
Between (0.8 V and 2.0 V): Undefined
High (2.0 – 3.465 V):
Transmitter Disabled
Open:
Transmitter Disabled
3. Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7-10 KΩ resistor on the host board to a supply less than
VccT +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
< VccT,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 operatio0n. 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 must be between
370 and 2000 mV differential (185 – 1000 mV single ended) according to the MSA. Typically it will be 1500mv differential.
6. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.135 – 3.465 V at the SFP connector pin. The in-rush current will
typically be no more than 30 mA above steady state supply current 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 500 – 2400 mV (250 – 1200 mV
single ended). However, the applicable recommended differential voltage swing is found in Table 5.
