coaxialkablage

Coaxialkabelage refers to the use of coaxial cables for transmitting electrical signals. A coaxial cable consists of an inner conductor, surrounded by an insulating layer, then a braided metal shield, and finally an outer insulating jacket. This construction is designed to protect the signal from external interference and prevent the signal from radiating outwards.

The primary function of coaxial cable is to carry radio frequency (RF) signals. This makes it widely used in telecommunications, cable television distribution, and data networking. In cable television, coaxial cables deliver broadcast signals from the headend to individual homes. In networking, they were historically used for Ethernet (e.g., 10BASE2 and 10BASE5 standards) before being largely superseded by twisted-pair cables.

The impedance of a coaxial cable, typically 50 or 75 ohms, is a critical characteristic that affects signal integrity. Matching the impedance of the cable, connectors, and connected devices minimizes signal reflections and power loss. Connectors like BNC and F-type are commonly used with coaxial cables. While coaxial cable offers good shielding and bandwidth, its rigidity and susceptibility to damage can be drawbacks compared to newer cable types. Despite these limitations, it remains relevant in various applications where its robust signal transmission capabilities are advantageous.
