1. An annular conductor for use in a multi-conductor cable, comprising:
- an annular support sheath, within which is contained a volume for containing optical fibers;
a braided weave surrounding said annular support sheath, within said braided weave being disposed a plurality of individual conductors, each of the individual conductors including;
a tensile core;
a conductor layer surrounding said tensile core;
a magnetic matrix layer surrounding said conductor layer, said magnetic matrix layer having a spatially anisotropic value of permeability or permiftivity; and
an insulating layer surrounding said matrix layer.

Abstract
A cable system is provided which can accommodate electrical and optical cabling. The conductors of the system employ a layer which is impedance-matched to space, decreasing their cross-section to electromagnetic interference. The conductors of the system also employ a layer which symmetrizes electromagnetic interference signals, reducing the effect of interference and crosstalk on the signals carried by the conductors. The system also includes a node interface device for connection to a global electrical and fiber network. The node interface device connects to a user interface device through the cable.
