Feature
Electrostatic Discharge (ESD) to
the Electrical Pins
Test Method
MIL-STD-883C
Method 3015.4
Performance
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. However,
it should be noted that final margin depends on the customer's board and
chassis design.
Immunity
Variation of IEC 61000-4-3
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.
In all well-designed chassis,
two 0.5" holes 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.
Immunity
Equipment utilizing these
transceivers will be subject to
radio-frequency
electromagnetic fields in some
environments. These
transceivers have a high
immunity to such fields.

Transceiver Reliability and
Performance Qualification Data
The 1 x 9 transceivers have
passed Agilent reliability and
performance qualification
testing and are undergoing
ongoing quality monitoring.
Details are available from your
Agilent sales representative.
Accessory Duplex SC Connectored
Cable Assemblies
Agilent recommends for
optimal coupling the use of
flexible-body duplex SC con-
nectored cable.
Accessory Duplex ST Connectored
Cable Assemblies
Agilent recommends the use of
Duplex Push-Pull connectored
cable for the most repeatable
optical power coupling
performance.
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.
