What results from pulse transmission through optical fibers over distance?

Pulse transmission through optical fibers over distance primarily leads to a decrease in signal strength. This phenomenon occurs due to various factors, including attenuation, which is the gradual loss of signal power as light travels through the fiber. Over longer distances, the effects of scattering, absorption, and dispersion become more pronounced, resulting in a weakened signal.

The decrease in strength can impact the quality and integrity of the transmitted data, requiring the implementation of signal regeneration or amplification techniques to maintain effective communication over longer distances. Therefore, understanding how distance affects signal strength is vital in the design and maintenance of optical communication systems.
