What is an example of transport media in a telecommunications network?

The correct answer identifies coaxial cable as an example of transport media in a telecommunications network. Coaxial cable is designed to carry signals, typically in the radio frequency spectrum, effectively transferring data over both short and long distances. Its construction, featuring a central conductor, insulating layer, metallic shield, and outer insulating layer, provides excellent shielding against electromagnetic interference, making it ideal for reliable data transmission.

Transport media refers to the physical mediums through which communication signals flow. While coaxial cable serves this purpose well, fiber optic cable and twisted pair cable are also viable transport media but differ in their technology and application. Fiber optic cables use light to transmit data at high speeds over long distances, offering greater bandwidth compared to coaxial. Twisted pair cable, often used in local area networks, transmits signals through pairs of wires twisted together to reduce interference but typically has lower bandwidth and distance capabilities than coaxial and fiber optic cables.

Wireless signals, while a mode of communication, do not qualify as transport media in the traditional sense since they rely on electromagnetic radio waves rather than a physical medium for signal transit. Thus, coaxial cable stands out in the context of transport media as a practical and established choice in telecommunications networks.
