koaksiaalses

Koaksiaalses refers to a coaxial cable, a type of electrical cable commonly used for transmitting radio frequency signals. It consists of an inner conductor surrounded by an insulating layer, which is then surrounded by a braided metal shield. The outer jacket protects the cable from environmental damage. The term "coaxial" describes the geometric arrangement where the inner conductor and the outer shield share the same geometric axis. This design helps to reduce electromagnetic interference and signal loss, making coaxial cables suitable for a variety of applications.

Coaxial cables are frequently employed in television broadcasting, cable television distribution, and as antenna feeders for radio transmitters and receivers. They are also used in computer networking, particularly in older Ethernet standards like 10BASE2 and 10BASE5. The impedance of a coaxial cable is a crucial characteristic, typically standardized at 50 ohms or 75 ohms, which is important for matching with connected equipment to ensure maximum power transfer and minimize reflections. Different types of coaxial cables exist, varying in size, shielding effectiveness, and intended use. The construction of a coaxial cable directly influences its performance characteristics, such as bandwidth and attenuation.
