The HFBR-5602 complies with

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 E

PROM 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 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.

Outline Drawing

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.
