Detailed explanation-1: -Copper cabling transmits data through twisted pairs of copper wires and fiber cables transmit data using light.
Detailed explanation-2: -Speed, Bandwidth & Distance Coaxial cable and twisted pair cable are copper or copper-based wire surrounded by insulation with other materials. Both of them can transmit television, telephone and data with electrical signals.
Detailed explanation-3: -Typically, copper cables measure at least two millimeters in diameter. When it comes to internet connectivity, these cables transmit data in the form of electrical signals. On average, a copper-based internet connection provides speeds of up to 300 Mbps. Theoretically, copper cables can offer speeds of up to 10 Gbps.
Detailed explanation-4: -This is also the origin of the term twisted pair cable, which is often used synonymously. Four-pair cables are usually used. A copper data cable conducts electrical currents and has multiple insulation. The most common areas of application are in telecommunications, message transmission and computer technology.
Detailed explanation-5: -Data is transmitted on copper cables as electrical pulses. A detector in the network interface of a destination device must receive a signal that can be successfully decoded to match the signal sent. However, the longer the signal travels, the more it deteriorates in a phenomenon referred to as signal attenuation.
