A twisted pair line rejects electromagnetic interference (EMI) and crosstalk better than a single wire or an untwisted pair.
Care has to be taken with analog audio to avoid audible 'breakthrough' (aka "crosstalk") from the LTC track to the audio tracks.
G.vector crosstalk cancelling feature (ITU-T G.993.5) can be used to increase range at a given bitrate, e.g. 100 Mbit/s at up to 500 meters.
Each of the four pairs in a cat 5 cable has differing precise number of twists per meter to minimize crosstalk between the pairs.
As noted in ANSI/TIA/EIA-568-B-2 standard for backbone applications This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and crosstalk from other pairs.
However tiny amounts of random birefringence in such a fiber, or bending in the fiber, will cause a tiny amount of crosstalk from the vertical to the horizontal polarization mode.
