Regulatory Compliance
These transceiver products are
intended to enable commercial
system designers to develop
equipment that complies with the
various regulations governing
certification of Information
Technology Equipment. See the
Regulatory Compliance Table
for details. Additional information
is available from your Hewlett-
Packard 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.

The second case to consider is
static discharges to the exterior
of the equipment chassis
containing the transceiver parts.
To the extent that the duplex SC
connector receptacle 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 requirements
of FCC in the United States,
CENELEC EN55022 (CISPR 22) in
Europe and VCCI in Japan.
The HFBR-5208 EMI has been
characterized without a chassis
enclosure to demonstrate the
robustness of the parts integral
shielding. Performance of a
system containing these
transceivers within a well
designed chassis is expected to
be better than the results of these
tests with no chassis enclosure.
Immunity
Equipment utilizing these
HFBR-5208 transceivers will be
subject to radio-frequency
electromagnetic fields in some
environments. These transceivers,
with their integral shields, have
been characterized without the
benefit of a normal equipment
chassis enclosure and the results
are reported below. Performance
of a system containing these
transceivers within a well-
designed chassis is expected to
be better than the results of these
tests without a chassis enclosure.

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.
Typically provide a 4 dB margin to FCC Class B
and a 1 dB margin to the other noted standard
limits when tested with the transceiver mounted to
a circuit card without a chassis enclosure at
frequencies up to 1 GHz. An ATM scrambled
pattern is assumed. Margins above 1 GHz are
dependent on customer board and chassis design.
Typically show no measurable effect from a 10 V/m
field swept from 10 MHz to 1 GHz applied to the
transceiver when mounted to a circuit card
without a chassis enclosure.
FCC Class B
Immunity
Variation of IEC 801-3
The HFBR-5208 LED transmitters are classified as IEC 825-1 Accessible Emission Limit (AEL) Class 1.
AEL Class 1 LED devices are considered eye safe.
