Optical cables, also named as TOSLINK, are optical fiber cables designed primarily to carry audio signals between consumer audio equipments nowadays. Gadgets today such as DVD players and home theater systems generally have these digital optical outputs. They enable digital audio to stream from one source to a specific decoder, and then out to speakers. These cables deliver high quality audio every time.

These days, S/PDIF standards are quite common for such audio streams. Home theater systems, BluRay players and even gaming consoles typically have such interface. These things let users actually stream music and audio straight from their gadgets to decoders, so people can enjoy full DTS or Dolby Digital sounds right at home. High fidelity audio streaming is then made possible with such cables because of their speeds.

When it first came out in 1983, optical cables were only capable of carrying speeds of up to 3.1 Mbit per second. Today, they are able to have bandwidths of up to 125 Mbit per second, clearly showing that they indeed have evolved. Fibre optic cables are utilized.

Homes with home theaters generally use these cables alongside HDMI cables. Running from the source to their decoders, it then decodes the light signals and transfers them to the speakers. Originally designed to support 48KHz at 20-bit, this technology has quite developed for the past few years. These days, digital audio can support every audio format, including Dolby Digital and DTS surround sound technologies.

There are many manufacturers of optical cables nowadays. Optical fibers are coated with resin, and then a plastic jacket to reinforce its strength. These layers do not interfere with the fiber optics, as they only protect the cable itself. Generally, fibers inside are made of thin and transparent plastic or glass. Such cables transmit light which is then encoded or decoded into audio streams. Each end of the cables have connectors which go in optical audio ports found in players and encoders.

Computers today also utilize this interface in audio, as some audio cards today support 5.1 or 7.1 speaker setups. Home theaters are now possible to make, and is quite easy to setup, as well. External audio processors which can be easily hooked up to laptops and desktops can also be used, to easily upgrade your computer’s capability to transmit high fidelity audio.

Investing in good cables and equipment can truly give you unparalleled audio experience.
