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.
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.

Performance
Meets Class 1 (<1999 Volts).
Withstand up to 1500 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.
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.
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.
