The recent invention of the digital optical cable has enabled audiophiles to enjoy an outstanding faultless transmission of their multi-channel soundtracks via transmission by a digital optical cable. The digital optical cable is becoming the most commonly used cable to connect game consoles, cd players, digital home theaters, and other digital hi-fi electronic equipment. This type of cable is also used to connect dvd players to modern day surround sound systems. The digital optical cable has a fiber-optic connection. It transfers digital audio signals such as PCM, Dolby Digital and DTS between a source device and an audio video receiver via fiber optic light signals. The digital optical cable is also referred to as a TOSLINK connection.
Digital optical cables use a superior-grade optical fiber that can provide the most natural sound and clearest picture from your digital video/audio components. The optical fiber transfers digital signals through pulsating light with no EM/RF interference. This gives you the most natural sound and detailed video. There are some low grade optical cables on the market but they are made out of inferior optical-fiber material. The digital optical cable is the best because it uses polished optical terminations whereas an ordinary optical cable uses hot-plate termination. The advantage that the digital optical cable has over the ordinary optical cable is that there will be better clarity and no loss of sound definition.
A digital optical cable sends light signals without needing to send the data by electricity. This makes the transfer of data lightening fast. Because these type of cables can transfer the data so much faster than other cables they have become the most popular and widely used cables that are for sale on the market today for those who are setting up home theaters.
If you are choosing between an older coaxial cable and a new digital optical cable, the latter cable is the best choice. The digital optical cable does not have the same limitations that the coaxial cable has. The coaxial cable transmits data via electrical impulses rather than transmitting data via light pulses like the digital optical cable does. Because electricity is not used the signal does not weaken or degrade. It will always be received in its purest form.
Digital optical cables are not without a few drawbacks however. One of them is the fact that they are very expensive. They cost about 50% more than the coaxial cable. True audiophiles are happily paying the increased cost because these cables give them the high quality sound they want. Another drawback is the fact that if the cable is bent or kinked it may cause problems with the signal transmission since light does not bend. Even a slight bending of the cable can produce less than desired results. If you have right angle requirements for your home theater system or bends or curves then you will need to make with your cable, you should use the coaxial digital cables instead. The core of the digital optical cable needs to remain completely round. There should also be a non-reflective cladding surrounding it that also remains round.
High quality digital optical cables are made from multiple fibers that are very small in diameter. Ones that are made with fibers that are greater than 200 micrometers or those that only use one single fiber are not going to deliver the best signal or natural sound. These are the cables that have plastic fiber interconnects rather than the polished optical terminations that the higher quality digital optical cables have. You can find digital optical cables online or in your favorite retail audio stores.
