ABSTRACT:
The invention relates to a switching device comprising a plurality of inputs and outputs which are interconnected by an interconnection point matrix for transmitting electric signals supplied from the inputs to the outputs via transmission lines in accordance with a predefined switching plan. Each transmission line comprises a signal path for conveying the electric signals and a voltage reference path. The interconnection points are arranged in the matrix in such a way that two distinct transmission lines comprise one common voltage reference path. Application: packet switching in optical transmissions.
