Performance

Meets Class 2 (2000 to 3999 Volts)

Withstand up to 2200 V applied between

electrical pins.

Typically withstand at least 25 kV without damage

when the Duplex SC Connector Receptacle is

contacted by a Human Body Model probe.

Typically provide a 13 dB margin (with duplex SC

package) or a 9 dB margin (with duplex ST

package) to the noted standard limits when tested

at a certified test range with the transceiver

mounted to a circuit card without a chassis

enclosure.

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 first case is during handling

of the transceiver prior to mount-

ing 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.

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 Hewlett-Packard will be

required to meet the require-

ments of FCC in the United

States, CENELEC EN55022

(CISPR 22) in Europe and VCCI

in Japan.
