Optical versus electrical digital audio output

The electrical connection has more bandwidth, typical more than 50MHz and this will maintain the pulse quality at the receiver end, to reduce jitter.

However there is noise emission from the digital pulses, which potentially can disturb the video signal or TV/FM receiver. A short cable e.g. less than 75cm and not crossing the video cables or antenna cables is necessary. Further there can be problems of disturbancies through the receivers ground plane, which can add new jitter.

The optical connection has less bandwidth around 10 MHz, but still around 5 times more than the bit rate of a SPDIF digital audio signal, so that the signal quality is maintained.

The optical connection is completely free from ground return current and noise emission. And this will in many cases more than justify the use of a optical connection in a complicated audio/video system.

If you face any noise problems with an electrical connection then change to an optical connection.
