• Any recommendations for good quality SPDIF optical audio cable? I'm going to have a run of 6m or so which, according to some things I've read, can be pushing it a bit.

  • Can’t fibre optic runs be as long as you like without picking up external interference, with it being light and that?

  • They don't get electromagnetic interference, but they do suffer from attenuation and pulse broadening. Toslink is designed to be cheap, robust and easy to connect, so it is limited to a maximum length of 10 metres for polymer fibres.
