What is a common communication technology used in low voltage systems?

Ethernet is widely recognized as a common communication technology used in low voltage systems. It functions as a standard networking protocol that facilitates data transfer over local area networks (LANs). Ethernet's robustness, scalability, and support for various bandwidths make it an ideal choice for low voltage applications, such as security systems, building automation, and telecommunication systems. It enables devices to communicate effectively within a network, which is essential for real-time handling and monitoring in low voltage environments.

While other technologies like cable television, fiber optics, and WiFi have their respective uses, they serve different primary functions or operate in different contexts. For instance, cable television is primarily used for delivering broadcast content rather than data communication between devices within a network. Fiber optics, while it offers high-speed data transfer, is not typically categorized strictly under low voltage systems as it often pertains to the medium of transmission rather than the standard communication protocols used in local networks. WiFi, although a popular communication method, is generally used for wireless networking and may not always align with the wired connectivity often seen in low voltage special systems installations.
