Feature Test Method Performance
Electrostatic Discharge
(ESD) to the Electrical Pins
MIL-STD-883C
Method 3015.4
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 Interfer-
ence (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 nal margin
depends on the customer’s board and chassis design.
Immunity Variation of IEC 61000-4-3 Typically show no measurable eect from a 10 V/m eld swept from
10 to 450 MHz applied to the transceiver when mounted to a circuit
card without a chassis enclosure.
Immunity
Equipment utilizing these transceivers will be subject to
radio-frequency electromagnetic elds in some environ-
ments. These transceivers have a high immunity to such
elds.
For additional information regarding EMI, susceptibility,
ESD and conducted noise testing procedures and results
on the 1 x 9 Transceiver family, please refer to Applica-
tions Note 1075, Testing and Measuring Electromagnetic
Compatibility Performance of the AFBR-510X/520X Fiber
Optic Transceivers.
Transceiver Reliability and Performance Qualication Data
The 1 x 9 transceivers have passed Avago Technologies
reliability and performance qualication testing and
are undergoing ongoing quality monitoring. Details are
available from your Avago Technologies sales represen-
tative.
Accessory Duplex SC Connectored Cable Assemblies
Avago Technologies recommends for optimal coupling
the use of exible-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.
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.
