Based on the transmission medium and application, bus cables can be classified as follows:
- Twisted-pair cable: Consists of two insulated conductors twisted together, reducing electromagnetic interference; commonly used in local area networks (LANs) and industrial control systems.
- Coaxial cable: Composed of a center conductor, insulation layer, metallic shielding layer, and outer sheath; suitable for high-frequency signal transmission, such as in video surveillance systems.
- Fiber optic cable: Utilizes optical pulses to transmit data, offering high bandwidth and interference resistance; primarily used for long-distance communication.
- Multi-core cable: Contains multiple independently insulated conductors; suitable for multi-point connections between complex devices.
