different types of cable cords
Twin-lead â This type of cable is a flat two-wire line. It is commonly called a 300 Ï line because the line has an impedance of 300 Ï. It is often used as a transmission line between an antenna and a receiver (e.g., TV and radio). These cables are stranded to lower skin effects.
An electrical cable is an assembly consisting of one or more conductors with their own insulations and optional screens, individual covering(s), assembly protection and protective covering(s). Electrical cables may be made more flexible by stranding the wires.
Standard HDMI Cable. The Standard HDMI cable is designed to handle most home applications, and is tested to reliably transmit 1080i or 720p video â the HD resolutions that are commonly associated with cable and satellite television, digital broadcast HD, and upscaling DVD players.
Optical cables transfer data at the speed of light in glass. This is the speed of light in vacuum divided by the refractive index of the glass used, typically around 180,000 to 200,000 km/s, resulting in 5.0 to 5.5 microseconds of latency per km. Thus the round-trip delay time for 1000 km is around 11 milliseconds.
