Agilent HFBR-5602/HFCT-5612 Gigabit Interface Converters (GBIC

Agilent 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 specification 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 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 or maintenance 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 componentdamaging 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-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.

Annex E of the GBIC specification
Revision 5.4. In the Fibre Channel
environment, the HFBR-5602
achieves 300 m transmission
distance with 62.5 µm and 50 µm
multimode fibre.
The HFCT-5612 complies with
Annex C of the GBIC specification
Revision 5.4 and reaches 10 km
with 9/125 µm single mode fiber.
Both the HFBR-5602 and the
HFCT-5612 are Class 1 Eye Safe
laser devices.
Serial Identification
The HFBR-56xx and HFCT-5612
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.
2
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 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 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.

An outline drawing is shown in
Figure 1. More detailed drawings
are shown in Gigabit Interface
Converter specification 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
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.

Interpretation by host
Serial module definition protocol
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 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 silicon
PIN photodiode mounted together
with a custom, silicon bipolar
transimpedance preamplifier IC,
in an OSA. This OSA interfaces to
a custom silicon bipolar circuit
that provides post-amplification
and quantization. The postamplifier 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.
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 postamplifier includes a Signal Detect
circuit that provides TTL
compatible logic-low output in
response to the detection of a
usable input optical signal.
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.
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.
