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. However, it should be noted that final margin
depends on the customer’s board and chassis design.
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.
Electromagnetic Interference (EMI)
Most equipment designs utilizing these high speed trans
ceivers from Avago Technologies will be required to meet
the requirements of FCC in the United States, CENELEC
EN55022 (CISPR 22) in Europe and VCCI in Japan.
In all well-designed chassis, two 0.5” holes for ST con-
nectors 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 environ-
ments. These transceivers have a high immunity to such
fields.

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