Koaxialverkabelungen

Koaxialverkabelungen, often simply called coax cables, are a type of electrical cable used to transmit radio frequency energy. They consist of an inner conductor surrounded by an insulating layer, which is then surrounded by a braided metal shield. An outer insulating jacket encloses the entire assembly. This construction helps to minimize signal loss and interference, making them suitable for applications requiring stable signal transmission.

The most common type of coaxial cable is the 50-ohm or 75-ohm cable, distinguished by the impedance of the cable. 50-ohm cables are typically used for data transmission and radio frequency applications, while 75-ohm cables are prevalent in television and video distribution. The inner conductor carries the signal, and the braided shield acts as a ground and also protects the signal from external electromagnetic interference.

Coaxial cables have been widely used for cable television, internet connections (via cable modems), and various radio transmission systems. While newer technologies like fiber optics are becoming more common for high-speed data, coaxial cables remain a reliable and cost-effective solution for many applications. Their robustness and relatively simple installation contribute to their continued relevance.
