Low Voltage Differential Signaling (LVDS) wire is an electrical standard for digital signalling that allows for the exceptionally high-speed transmission of data over twisted copper lines. Additionally, it outlines the electrical level details necessary for input and output compatibility on integrated circuit devices.
As this is the only physical layer description, there are numerous standards for data transmission and application usage; nonetheless, you should layer a data link layer according to our OSI model on top of it. The LVDS Twinax cable from FLU-TEF WIRES & CABLES PVT. LTD. is distinguished from single-conductor cables by its two twisted conductors, which offer higher protection from environmental influences and lower cable loss. Due to their great efficiency, twin conductors are frequently employed in differential signalling applications that need a limited range and fast speed. LVDS Twinax cables are the best choice for data transmission and information service applications because of their high-speed capabilities.
