Abstract
A high frequency signal and a low frequency signal are coupled onto a pair of conductors providing a communication link between two computer components. The high frequency signal may be a differentially coupled Fibre Channel 8B/10B encoded signal. A diplexer includes a low pass filter for attenuating the Fibre Channel signal and a high pass filter for separately attenuating the low frequency signal. A two-way communication link may be provided over twinax cable. An environmental monitor may be in connection with the low frequency communication path.
