Agilent HFBR-5601/HFCT-5611
Gigabit Interface Converters
(GBIC) for Gigabit Ethernet
Data Sheet
Description
The HFBR-56xx/HFCT-56xx
family of interface converters
meet the Gigabit Interface
Converter specification Rev. 5.4,
an industry standard. The family
provides a uniform form factor for
a wide variety of standard
connections to transmission
media. The converters can be
inserted or removed from a host
chassis without removing power
from the host system.
The converters are suitable for
interconnections in the Gigabit
Ethernet hubs and switches
environment. The design of these
converters is also practical for
other high performance, point-to-
point communication requiring
gigabit interconnections. Since
the converters are hot-pluggable,
they allow system configuration
changes simply by plugging in a
different type of converter.

The mechanical and electrical
interfaces of these converters to
the host system are identical for
all implementations of the
converter regardless of external
media type. A 20-pin connector is
used to connect the converter to
the host system. Surge currents
are eliminated by using pin
sequencing at this connector and
a slow start circuit. Two ground
tabs at this connector also make
contact before any other pins,
discharging possible component-
damaging static electricity. In
addition, the connector itself
performs a two-stage contact
sequence. Operational signals and
power supply ground make
contact in stage 1 while power
makes contact in stage 2.
The HFBR-5601 has been
developed with 850 nm short
wavelength VCSEL technology
while the HFCT-5611 is based on
1300 nm long wavelength Fabry
Perot laser technology.

The HFBR-5601 complies with
Annex G of the GBIC specification
Revision 5.4. In the 1000 BASE-SX
environment the HFBR-5601
achieves 220 m transmission
distance with 62.5 µm and 500 m
with 50 µm multimode fiber
respectively.
The HFCT-5611 complies with
Annex F of the GBIC specification
Revision 5.4 and reaches 10 km
with 9/125 µm single mode fiber.
Both the HFBR-5601 and the
HFCT-5611 are Class 1 Eye Safe
laser devices.
Serial Identification
The HFBR-56xx and HFCT-5611
family complies with Annex D
(Module Definition 4) of the GBIC
specification Revision 5.4, which
defines the Serial Identification
Protocol.
Definition 4 specifies a serial
definition protocol. For this
definition, upon power up,
MOD_DEF(1:2) (Pins 5 and 6 on
the 20-pin connector) appear as
NC. Pin 4 is TTL ground. When the
host system detects this
condition, it activates the public
domain serial protocol. The
protocol uses the 2-wire serial
CMOS E2PROM protocol of the
ATMEL AT24C01A or similar.
The data transfer protocol and the
details of the mandatory and
vendor specific data structures
are defined in Annex D of the
GBIC specification Revision 5.4.
Regulatory Compliance
See the Regulatory Compliance
Table for the targeted typical and
measured performance for these
transceivers.
The overall equipment design will
determine the level it is able to be
certified to. These transceiver
performance targets are offered as
a figure of merit to assist the
designer in considering their use
in equipment designs.
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 inserting it
into the host system. It is
important to use normal ESD
handling precautions for ESD
sensitive devices. These
precautions include using
grounded wrist straps, work
benches, and floor mats in ESD
controlled areas.
The second case to consider is
static discharges during insertion
of the GBIC into the host system.
There are two guide tabs
integrated into the 20-pin
connector on the GBIC. These
guide tabs are connected to
circuit ground. When the GBIC is
inserted into the host system,
these tabs will engage before any
of the connector pins. The mating
connector in the host system must
have its tabs connected to circuit
ground. This discharges any stray
static charges and establishes a
reference for the power supplies
that are sequenced later.
Electromagnetic Interference (EMI)
Most equipment designs utilizing
these high-speed transceivers
from Agilent will be required to
meet the requirements of FCC in
the United States, CENELEC
EN55022 (CISPR 22) in Europe
and VCCI in Japan.
Immunity
Equipment utilizing these
transceivers will be subject to
radio-frequency electromagnetic
fields in some environments.
These transceivers have good
immunity to such fields due to
their shielded design.
Eye Safety
Laser-based GBIC transceivers
provide Class 1 (IEC 60825-1) and
Class I (US 21 CFR[J]) laser eye
safety by design. Agilent has
tested the current transceiver
design for compliance with the
requirements listed below under
normal operating conditions and
for compliance under single fault
conditions.

Optical Power Budget and
Link Penalties
The worst-case Optical Power
Budget (OPB) in dB for a fiber
optic link is determined by the
difference between the minimum
transmitter output optical power
(dBm avg) and the lowest receiver
sensitivity (dBm avg). This OPB
provides the necessary optical
signal range to establish a working
fiber-optic link. The OPB is
allocated for the fiber-optic cable
length and the corresponding link
penalties. For proper link perform-
ance, all penalties that affect the
link performance must be acc-
ounted for within the link optical
power budget. The Gigabit/sec
Ethernet (GbE) IEEE 802.3z
standard identifies, and has
modeled, the contributions of
these OPB penalties to establish
the link length requirements for
62.5/125 µm and 50/125 µm multi-
mode fiber usage. In addition,
single-mode fiber with standard
1300 nm Fabry Perot lasers have
been modeled and specified. Refer
to IEEE 802.3z standard and its
supplemental documents that
develop the model, empirical
results and final specifications.
10 km Link Support
As well as complying with the LX
5 km standard, the HFCT-56xx
specification provides additional
margin allowing for a 10 km
Gigabit Ethernet link on single
mode fiber. This is accomplished
by limiting the spectral width and
center wavelength range of the
transmitter while increasing the
output optical power and
improving sensitivity. All other LX
cable plant recommendations
should be followed.
CAUTION:
There are no user serviceable
parts nor any maintenance
required for the HFBR-56xx and
HFCT-56xx product family. All
adjustments are made at the
factory before shipment to our
customers. Tampering with or
modifying the performance of any
Agilent GBIC unit will result in
voided product warranty. It may
also result in improper operation
of the circuitry, and possible
overstress of the semiconductor
components. Device degradation
or product failure may result.
Connection of either the
HFBR-5601 or the HFCT-5611 to a
non-approved optical source,
operating above the
recommended absolute maximum
conditions, or operating in a
manner inconsistent with unit
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 the laser
product under the provisions of
US 21 CFR (Subchapter J).

Short Wavelength GBIC: HFBR-5601
Transmitter Section
The transmitter section consists
of an 850 nm VCSEL in an optical
subassembly (OSA), which mates
to the fiber cable. The VCSEL
OSA is driven by a custom, silicon
bipolar IC which converts
differential logic signals into an
analog Laser Diode drive current.
Receiver Section
The receiver includes a GaAs PIN
photodiode mounted together
with a custom, silicon bipolar
transimpedance preamplifier IC,
in an OSA. The OSA interfaces to
a custom silicon bipolar circuit
that provides post-amplification
and quantization. The post-
amplifier includes a Signal Detect
circuit that provides TTL
compatible logic-low output in
response to the detection of a
usable input optical signal.
Eye Safety Design
The laser driver is designed to be
Class 1 eye safe (CDRH21 CFR(J),
IEC 60825-1) under a single fault
condition. To be eye safe, only
one of two results can occur in
the event of a single fault. The
transmitter must either maintain
normal eye safe operation or the
transmitter should be disabled.
There are three key elements to
the safety circuitry: a monitor
diode, a window detector circuit,
and direct control of the laser
bias. The window detection circuit
monitors the average optical
power using the monitor diode. If
a fault occurs such that the dc
regulation circuit cannot maintain
the preset bias conditions within
±20%, the transmitter will
automatically be disabled. Once
this has occurred, an electrical
power reset will allow an
attempted turn-on of the
transmitter. TX_FAULT can also
be cleared by cycling TX_DISABLE
high for a time interval >10 µs.
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter
in isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that
limiting values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum
ratings for extended periods can adversely affect device reliability.

Transmitter Section
The transmitter section consists
of a 1300 nm MQW Fabry Perot
Laser in an optical subassembly
(OSA), which mates to the fiber
optic cable. The Laser OSA is
driven by a custom, silicon bipolar
IC which converts differential
PECL logic signals (ECL
referenced to a +5 V supply) into
an analog drive current to the
laser.
The laser driver IC incorporates
temperature compensation and
feedback from the OSA to
maintain constant output power
and extinction ratio over the
operating temperature range.
Receiver Section
The receiver includes a PIN
photodiode mounted together
with a custom, silicon bipolar
transimpedance preamplifier IC,
in an OSA. The OSA interfaces to
a custom silicon bipolar circuit
that provides post-amplification
and quantization. The post-
amplifier includes a Signal Detect
circuit that provides TTL
compatible logic-low output in
response to the detection of a
usable input optical signal.
Eye Safety Design
The laser driver is designed to be
Class 1 eye safe (CDRH21 CFR(J),
IEC 60825-1) under a single fault
condition.
There are three key elements to
the safety circuitry: a monitor
diode, a window detector circuit,
and direct control of the laser
bias. The window detection circuit
monitors the average optical
power using the photo diode in the
laser OSA. If a fault occurs such
that the dc bias circuit cannot
maintain the preset conditions
within ±20%, TX_FAULT (Pin 10)
will be asserted (high).
Note: Under any single fault, the
laser optical output power will
remain within Class 1 eye safe
limits.
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter
in isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that
limiting values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum
ratings for extended periods can adversely affect device reliability.
