What is the main benefit of lower attenuation found in fiber optic cables?

Lower attenuation in fiber optic cables primarily leads to reduced signal loss over long distances. This is a significant advantage, as it means that the signals transmitted through the fiber can travel farther without degrading, ensuring better quality and reliability in data transmission. Unlike traditional copper cables, which experience more signal loss over distance, fiber optic technology allows for clearer and stronger signals, thereby supporting high-speed internet and enhanced telecommunications performance. This attribute is crucial for applications that require high bandwidth and minimal interruptions, such as video streaming or large data transfers.

While increased strength, cheaper materials, or faster installation could be perceived advantages in specific contexts, they do not directly relate to the fundamental characteristic of attenuation and its impact on signal integrity in fiber optics. Thus, the primary benefit of lower attenuation is indeed the reduction in signal loss.
