Optical audio cable

To date, an optical audio cable is one of the most modern, and also reliable methods for data transmission. On optical fiber, data transmission is done using light. As everyone knows, light is one of the fastest phenomena in the world, so it is worthwhile to understand what a cable is like, how it works and what is needed.

Light is an electromagnetic wave of high frequency. If it passes through an optical fiber, it can simultaneously carry a very large amount of information. In this case, such a transmission method is stable and has a high immunity to electromagnetic radiation. When passing through the light guide, the light wave decays - this depends on the transparency, as well as other properties that optical fibers, in particular, an optical audio cable, possess.

Let's take a closer look at the example of the DAXX R07 optical cable. It is made of glass fibers, which have a high level of transparency. It also has a low dispersion coefficient, which ensures a stable data flow and a high light propagation speed. Due to these properties, the optical audio cable R07 in the family of interlocks is considered one of the best, so it is perfect for high-end home cinema.

The glass fiber of this cable is 280 thin fibers. The thickness of one fiber is 53 microns. Each fiber is lacquered with a special reflective layer, which has a high refractive index - this contributes to the formation of a smooth flow of light with the minimum possible attenuation. This design provides high stability when transmitting a large amount of data, which is why for audio signals, the R07 optical cable is one of the best.

To protect against mechanical damage, stranded fiber is poured with a special buffer, and for maximum flexibility of the entire structure, a double layer of polyvinyl chloride is used. From excessive bends, the cable protects the outer nylon screen. Metal connectors ensure durability of use.

Before an electrical coaxial cable, an optical audio cable has several advantages:

- Optics has the ability to transmit large amounts of digital information;

- with the help of fiber can be made between the two components of the decoupling on the "ground". This is especially true when the computer's system unit is connected to the receiver.

High-quality fiber optic cable is not cheap. It's also expensive to implement it (up to $ 40-50). With budget equipment it is difficult to take advantage of the "optics", so very often instead of an optical cable, users choose a cheaper coaxial digital cable.

Often, specialists are asked whether it is necessary to buy an expensive cable, because most of the satellite receivers are equipped with only an optical digital output? So, expensive cable is not really needed. In satellite television, the sound quality is not the highest (the digital audio stream has a low bitrate), so for these purposes, an optical audio cable can be bought the easiest, which costs about 10-12 dollars.
