What is a major benefit of using fiber-optic cables in telecommunications?

A major benefit of using fiber-optic cables in telecommunications is their ability to transmit signals over long distances without significant loss. This is primarily due to the way light travels through the optical fibers. Unlike electrical signals carried by copper cables, light signals can travel much further without degradation, which allows for higher data rates and longer spans between repeaters or amplifiers.

This capability is essential for modern telecommunications systems, including internet and data services, as it enables efficient and high-speed communication across vast networks. The low attenuation of optical signals means that fewer repeaters are needed compared to traditional metal cables, enhancing overall system performance and reducing costs related to maintenance and infrastructure.

While fiber-optic cables do offer advantages related to weight and resistance to certain types of damage, the ability to maintain signal integrity over long distances is a defining feature that elevates them above other transmission technologies in the context of telecommunications.
