Telecommunications cable
Telecommunications cable is a type of guided transmission medium. Telecommunications are based on transmitting and receiving modulated waves/signals through a medium. Types of telecommunications cable include:[1][2] electrical cables when electric current is carried; transmission lines and waveguides when electromagnetic waves are transmitted; optical fibers when light signals are transmitted.
When the distances involved are very short, the term signal cable may be used, for analog or digital communication. A data cable is used in digital data communications. Data cabling must conform to certain standards and best practices to ensure reliable performance and safety.[3] When the distance between the transmitter and receiver is very far, an unguided or wireless medium transmission may be used, based on antennas.
Examples include:
- Ethernet cables (Cat 5, Cat 5e, Cat 6, Cat 6A)
- Token Ring cables (Cat 4)
- Coaxial cable mainly used for analog communication, sometimes used as a baseband digital data cable, such as in serial digital interface and thicknet and thinnet.
- Optical fiber cable
- Serial cable and parallel cable
- Cat2 or telephone cord
- USB cable
