HFBR-5602/HFCT-5612
Gigabit Interface Converters
(GBIC) for Fibre Channel
Data Sheet
Description
The HFBR-56xx/HFCT-56xx family of interface converters
meet the Gigabit Interface Converter specication Rev.
5.4. 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
Fibre Channel mass storage and data transfer environ-
ment. The design of these converters is also practical for
other high performance, point-to-point communication
requiring gigabit interconnections. Since the convert-
ers are hot-pluggable, they allow system conguration
changes or maintenance simply by plugging in a dierent
type of converter.
The mechanical and electrical interfaces of these convert-
ers to the host system are identical for all implementa-
tions 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. Opera-
tional signals and power supply ground make contact in
stage 1 while power makes contact in stage 2.

The HFBR-5602 has been developed with 850 nm short
wavelength VCSEL technology while the HFCT-5612 is
based on 1300 nm long wavelength Fabry Perot laser
technology.
The HFBR-5602 complies with Annex E of the GBIC speci-
cation Revision 5.4. In the Fibre Channel environment,
the HFBR-5602 achieves 300 m transmission distance
with 62.5 µm and 50 µm multimode bre.
The HFCT-5612 complies with Annex C of the GBIC speci-
cation Revision 5.4 and reaches 10 km with 9/125 µm
single mode ber. Both the HFBR-5602 and the HFCT-
5612 are Class 1 Eye Safe laser devices.
Serial Identication
The HFBR-56xx and HFCT-5612 family complies with
Annex D (Module Denition 4) of the GBIC specica-
tion Revision 5.4, which denes the Serial Identication
Protocol.
Denition 4 species a serial denition protocol. For this
denition, 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
dened in Annex D of the GBIC specication Revision
5.4.
Regulatory Compliance
See the Regulatory Compliance Table for the targeted
typical and measured performance for these transceiv-
ers.
The overall equipment design will determine the level it
is able to be certied to. These transceiver performance
targets are oered as a gure 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 rst 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 oor 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 shall engage before any of the connector pins. The
mating connector in the host system should 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 trans-
ceivers from Avago will be required to meet the require-
ments 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 elds in some environ-
ments. These transceivers have good immunity to such
elds 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.
Avago has tested the current transceiver design for
compliance with the requirements listed below under
normal operating conditions and for compliance under
single fault conditions.

cation Rev. 5.4.
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 Avago 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-5602 or the HFCT-5612 to
a non-approved optical source, operating above the rec-
ommended 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-5602
Transmitter Section
The transmitter section consists of an 850 nm VCSEL in
an optical subassembly (OSA), which mates to the ber
cable. The VCSEL OSA is driven by a custom, silicon
bipolar IC which converts dierential logic signals into
an analog Laser Diode drive current.
Receiver Section
The receiver includes a silicon PIN photodiode mounted
together with a custom, silicon bipolar transimpedance
preamplier IC, in an OSA. This OSA interfaces to a
custom silicon bipolar circuit that provides post-ampli-
cation and quantization. The post-amplier 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 trans-
mitter 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 aect 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 ber optic cable. The Laser OSA is driven by
a custom, silicon bipolar IC which converts dierential
PECL logic signals (ECL referenced to a +5 V supply) into
an analog drive current to the laser.
The laser driver IC incorporates temperature compensa-
tion 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 transimped-
ance preamplier IC, in an OSA. The OSA interfaces to a
custom silicon bipolar circuit that provides post-ampli-
cation and quantization. The post-amplier 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
