Regulatory Compliance

These transceiver products are

intended to enable commercial

system designers to develop

equipment that complies with

the various international

regulations governing certifica-

tion of Information Technology

Equipment. See the Regulatory

Compliance Table for details.

Additional information is

available from your Agilent

sales representative.

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 mounting it on the

circuit board. 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.

Electrostatic Discharge (ESD) to

the Electrical Pins

MIL-STD-883C

Method 3015.4

Meets Class 1 (<1999 Volts).

Withstand up to 1500 V applied between electrical pins.

Electrostatic Discharge (ESD) to

the Duplex SC Receptacle

Variation of

IEC 801-2

Typically withstand at least 25 kV without damage when the Duplex SC

Connector Receptacle is contacted by a Human Body Model probe.

Electromagnetic Interference

(EMI)

FCC Class B

CENELEC CEN55022

Class B (CISPR 22B)

VCCI Class 2

Transceivers typically provide a 13 dB margin (with duplex SC receptacle) or a 9

dB margin (with duplex ST receptacles) to the noted standard limits when

tested at a certified test range with the transceiver mounted to a circuit card

without a chassis enclosure.

Immunity

Variation of

IEC 801-3

Typically show no measurable effect from a 10 V/m field swept from 10 to 450

MHz applied to the transceiver when mounted to a circuit card without a

chassis enclosure.

The second case to consider is

static discharges to the exterior

of the equipment chassis con-

taining the transceiver parts.

To the extent that the duplex

SC connector is exposed to the

outside of the equipment

chassis it may be subject to

whatever ESD system level test

criteria that the equipment is

intended to meet.

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.

These products are suitable for

use in designs ranging from a

desktop computer with a single

transceiver to a concentrator

or switch product with large

number of transceivers.

In all well-designed chassis,

the two 0.5" holes required for

ST connectors to protrude

through will provide 4.6 dB

more shielding than one 1.2"

duplex SC rectangular cutout.

Thus, in a well-designed

chassis, the duplex ST 1 x 9

transceiver emissions will be

identical to the duplex SC 1 x

9 transceiver emissions.
