Coaxial cables
They are cables with an inner conductor surrounded by a tubular insulating layer made of a flexible material, with a high dielectric constant. They are a type of wire used for carrying a wide range of transmissions from the source to the device. They are basically cables and connectors of 75 ohm impedance and used to connect DVD players, Compact Disk (CD) and some DAT recorders to multichannel surround sound (Dolby Digital, DTS, etc) equipment. S/PDIF uses 75 ohm coaxial cable and RCA connectors. The 75 ohm coaxial cable is quite a low cost option, since the same cable is used for video transmission. Coaxial S/PDIF connections function well within a distance of 10 to 15 meters.
Optical cables – TOSLINK
The original creator of TOSLINK is Toshiba; TOSLINK was created in order to connect their CD players to their receivers. This idea was soon adopted by other CD player manufacturers. The intended use for the optical cable determines which type needs to be selected. Uses can range from use as submarine installation, power lines, attaching to aerial telephone poles, use in conduit, burial in trenches, and placement within paved streets. Early TOSLINK systems used the raw PCM data from the CD player; the S/PDIF standard has now become nearly universal for all the audio streams.

optical can carry both audio and video but separate cables are needed, hence HDMI is preferred.
