There is an explanation here: http://www.answers.com/topic/s-pdif S/PDIF is specified as an RCA connector but has an optical alternative also within the S/PDIF standard. The optical alternative is known as Toslink (Toshiba link) but uses the S/PDIF rather than the AES/EBU standard as far as the control bit is concerned. But it is common to call the RCA connector version of S/PDIF "SPDIF" and the optical connector version of S/PDIF "Toslink". The more important difference is between AES/EBU (which has a much higher voltage electrical interface) and S/PDIF.
