In which window(s) does the attenuation reach its minimum peak?
In which window(s) does the attenuation reach its minimum peak?
The correct answer is the third window (1550 nm). Attenuation in optical fibers is lowest in the third window, around 1550 nm, where the signal loss is minimized, making it ideal for long-distance communication.
