Today, an optical audio cable is one of the most modern, as well as reliable ways to transfer data. Fiber optic transmission of data using light. As everyone knows, light is one of the fastest phenomena in the world, so you should understand what a cable is, how it works and what it is for.
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. Moreover, this transmission method is stable and has high noise immunity to electromagnetic radiation. When passing through a fiber, the light wave damps - this depends on the transparency, as well as other properties that the fiber has, in particular an optical audio cable.
Let's take a closer look at 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 stream and high speed of light propagation. Due to these properties, the R07 optical audio cable in the inter-block family is considered one of the best, therefore, it is excellent for high-end home theater systems.
The glass fiber of this cable is 280 thin fibers. The thickness of one fiber is 53 microns. Each fiber is varnished with a special reflective layer, which has a high refractive index - this contributes to the formation of a smooth light stream with the minimum possible attenuation. This design provides high stability when transmitting a large amount of data, which is why for audio signals, the optical cable R07 is one of the best.
To protect against mechanical damage, the stranded fiber is poured with a special buffer, and for the maximum flexibility of the entire structure, a double layer of polyvinyl chloride is used. The cable is protected from excessive bending by the external nylon screen. Metal connectors ensure durability.
An optical audio cable has several advantages over an electric coaxial cable:
- Optics has the ability to transmit large amounts of digital information;
- using fiber optics, you can make a decoupling between the two components on the ground. This is especially true when the system unit of the computer is connected to the receiver.
High-quality fiber optic cable is not cheap. Its implementation will also cost a lot (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, experts are asked if it is necessary to buy an expensive cable, because most satellite receivers are equipped only with an optical digital output? So, an expensive cable is not really needed. In satellite television, the sound quality is not the highest (the digital audio stream has a low bit rate), so for these purposes you can buy an optical audio cable the simplest, which costs about 10-12 dollars.
