What is the coaxial cable? Oct 25, 2022

Audio coaxial cable: cable used for transmission of audio and audio signals

 

The Audio Coaxial Cable audio InterFace, standard SPDIF (Sony/Philips Digital InterFace), is jointly developed by SONY and Philips Corporation. The coaxial mark on the back plane of the audio-visual equipment is coaxial, which mainly provides the transmission of digital audio signals.

 

Audio Coaxial Cable

Coaxial audio interface

 

Its joint is divided into RCA and BNC two kinds. Coaxial audio is an audio interface, with input and output functions, different from the previous audio interface, it is a microphone (input interface) interface and headphones or audio (output interface) interface integrated together. Digital Coaxial is the interface that uses S/PDIF interface to output digital audio waves. A coaxial cable has two concentric conductors, and the conductor and the shield share the same axis. The coaxial cable is a copper conductor isolated by insulation material with an impedance of 75 ohm. Outside the inner insulation material is another ring conductor and its insulator. The whole cable is covered by a sheath of PVC or teflon material. The advantages of coaxial cable are stable impedance, high transmission bandwidth, and ensure the quality of audio. Although the standard connector of coaxial digital cable is BNC connector, RCA connector is mostly used in the market of coaxial digital cable. Digital coaxial interface adopts 75Ω impedance coaxial cable as the transmission medium, its advantages are constant impedance, transmission frequency band is wide, high quality coaxial cable frequency width can reach hundreds of megahertz. Standard joint of coaxial digital transmission line adopts BNC head, its impedance is 75Ω, and 75Ω coaxial cable, can ensure constant impedance, ensure correct signal transmission. That is to say on the wire that transmits collocation, should be with the 75 ohm coaxial wire that applies to transmit high frequency digital signal serves as collocation standard.
