Which is a result of poor quality in fiber optics?

In fiber optics, attenuation refers to the reduction in signal strength as it travels through the fiber. Poor quality in fiber optics can lead to increased attenuation, meaning that the light signal experiences greater loss over distance. This is typically caused by factors such as impurities in the glass, poor manufacturing processes, or damage to the fiber itself. Increased attenuation negatively affects the overall performance of the system, as it can lead to weaker signals that may not be adequately received or interpreted on the other end.

In contrast, enhanced bandwidth, better insulation, and higher signal speed are all characteristics that result from well-manufactured, high-quality fiber optics rather than poor quality. High-quality fibers are designed to minimize attenuation while maximizing signal integrity and performance.
