1. An isolating transformer for use in data communications system, the isolating transformer comprising:
a core;
a plurality of ports including a first port and a second port mechanically and topologically opposite each other;
a first conductor having a first coil,
connected in series to a first terminal and a second terminal of the first port, and wound around the core to provide the first coil;
a second conductor having a second coil,
connected in series to a third terminal and a fourth terminal of the second port, and wound around the core to provide the second coil;
wherein the first and second conductors are electrically isolated from one another;
wherein the first and second coils have a plurality of windings;
wherein the windings of the first and second coils are arranged around the core in such a way as to form a transmission line between them;
wherein the second coil is wound in such manner that the second port includes outputs located within the second coil.
