Coaxial digital audio cables allow signals to be transmitted in pulses of electricity through copper wires that are contained inside of the housing of the cable. The coaxial cable contains aluminum wraps that are engineered to block outside signal interference. The typical impedance for audio applications is 75 ohms and the cable type permits a larger overall bandwidth than an equivalent RCA cable. For the average home consumer, coaxial cables cost less than the optical S/PDIF type and are the most commonly used for home or personal digital audio needs as a result.
The two most common types of digital audio cables are coaxial and optical digital audio cables (also referred to as S/PDIF). Coaxial digital cables are the more commonly found type of cable and are very similar to the legacy, RCA analog type which most consumers have experience using. The primary difference between RCA and coaxial tends to be the thicker shielding required in the cable to prevent interference from outside noise sources.
The other type of digital audio cables are optical digital cables or as they’re more commonly referred to . These cables are completely different from any kind of cable most people know since they do not make use of a conductive metal such as copper. Instead, S/PDIF cables use pulses of light to transmit signals. The primary advantage to this mode of information is the elimination of radio and electromagnetic interference. As a result, the cables do not require as thick of shielding as the coaxial type. Another advantage of the S/PDIF type is that there is no degradation of signal over distance resulting in the same quality of signal exiting the cable as entering it. As a result, many audiophiles prefer the use of optical cables over coaxial. One significant shortcoming of the cable type is that if the optical cable gets bent, it can become damaged if installed in a high traffic area. The majority of modern audio components are built with ports for both S/PDIF and coaxial cable inputs and outputs.
One of the significant developments with the widespread adoption of the personal computer for home, business, and school use is the digitalization of media and the subsequent mass adaptation by consumers and industry. While digital media is not a new concept, it has only recently made its way into the “normal” household and is commonly supported by digital audio cables. As a result, higher quality audio playback is now supported while watching movies or listening to music that can approach (or at times exceed) the experience found in a high-end movie theater. While architecting the perfect home or work audio setup, some consumers neglect to identify the proper digital audio cable (vice analog) to use in their respective entertainment system.
