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.

25.4These 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

25.4 well-designed chassis, the duplex

ST 1x9 transceiver emissions will

be identical to the duplex SC 1x9

transceiver emissions.
