2.1.1
Signal Conditioning
Signal conditioning is a function of the type of network being serviced by the individual PMC240
channel. Copper cabling networks are provided with galvanic isolation whereas fiber optic links
are interfaced using SC-type fiber optic connectors with integrated transceivers for full duplex
operation.
