METHOD AND SYSTEM FOR TRANSMITTING SIGNALS ON A MULTI-CONDUCTOR CABLE

摘要

A method is provided for transmitting signals on a multi-conductor cable (12) formed from a plurality of conductors (1-7) surrounded by an armor (10), the plurality of conductors having a central conductor (7) surrounded by a first peripheral layer of conductors (1-6) with an even number of conductors symmetrically arranged around the central conductor. The two following transmission modes are carried out simultaneously: a common mode (TX1) that uses the central conductor (7) with a return on the armor (10), for transmitting a first signal (s1); and a differential mode (TX2) between a first path comprising all odd rank conductors (1,3,5) of the peripheral layer and a second path comprising all even rank conductors (2,4,6) of the peripheral layer, for transmitting a second signal (s2).
