Name a common application for limited-energy cabling.

Limited-energy cabling is primarily used for transmitting low-power signals and is an essential component in various applications. Voice over IP (VoIP) telephony systems are a common example of where limited-energy cabling is utilized. These systems rely on data networks for transmitting voice communications, making them dependent on structured cabling that meets specific standards for data integrity and efficiency.

VoIP systems typically use Ethernet cabling, which falls under the limited-energy cabling category. This cabling allows for the delivery of voice data alongside other network services, ensuring a seamless communication experience.

While the other applications like lighting control systems, power distribution units, and video surveillance systems can involve cabling, they often require different types of wiring or specialized installations that may not fit the limited-energy category in the same way as VoIP telephony does. Thus, the uniqueness of VoIP in relation to limited-energy cabling underscores its primary function in this context.
