What You Should Know About S/PDIF Cables

Generally the S/PDIF cable is used to deliver data from players such as DVD players, PC audio cards, CD players and other devices into stereo speakers. This cable was manufactured by Sony and Philips. It represents both the protocol for physical cable specifications and data link layer. The speakers usually use the cable to transport compressed data deciphered as a digital audio signal. It is used excellently as a connector between DVD players to speakers competent of DTS or Dolby surround sound. It can also implement signals of uncompressed audio from CD players to speakers or connecting computers to speakers.

There are plenty of SPDIF connectors readily available in the market. They can direct the transportation of digital audio signal between devices and components yet not affecting its quality. Besides, the cables can protect the signals from any unwanted electromagnetic interferences. The interface can also be used extensively to inter-connect some commercial or professional audio equipment.

The S/PDIF cable used to transport data via the jacks and RCA plugs will have a coaxial type of shield that arrests and grounds practically all of the audio spectra noise, including pink, brown and white. The ultimate ones, however, are the optical fiber cables. They have the noise-proof feature and they are way lossy in terms of number of feet the cable can accommodate the same signal compared to the coaxial cable. The noise immunity is the primary advantage of the digital transference in comparison to the usual analog transmissions. Although these cables are yet to be at the cheap and abundant mainstream level, it is gradually integrating itself into the market to be the reverse for the off-the-shelf mini CD-Rom decks to perform the Optical SPDIF I/O connection range.

Typical optical SPDIF connectors might contain one coaxial SPDIF input, two optical SPDIF inputs, one coaxial output and one optical SPDIF output and they are often secured by an accessible cover that can be removed during the installation of optical fiber.
