What is a common use for fiber optic cables in telecommunications?

Fiber optic cables are primarily used in telecommunications for long-distance data transmission with minimal loss. This is due to their ability to carry large amounts of data at high speeds over significant distances compared to traditional copper cables. Fiber optics utilize light signals to transmit information, which allows for greater bandwidth and reduced signal degradation over long distances.

This makes fiber optics particularly advantageous for telecommunications infrastructure, where maintaining signal integrity and high performance over long spans is crucial. The technology is essential for modern communication networks, including internet backbone connections, which require efficient and fast data transfer over extensive geographical areas.

In contrast, the other options do not align with the primary applications of fiber optic technology; audio connections do not typically benefit from the advantages of fiber optics, home appliances generally do not require the high-speed data transmission fiber provides, and while fiber can be used in local area networks, its most significant benefits shine in long-distance applications.
