Which detrimental outcome arises when optical coherence degrades within a long-distance fiber optic communication spool?

💡 Explanation

Increased bit error rate results when coherence is lost due to dispersion, fiber imperfections, or temperature variations. Because signal pulses spread and overlap via chromatic dispersion rather than maintaining sharp temporal boundaries, this induces incorrect bit interpretations; therefore, bit error rate occurs.
