What is Splice Loss in optical fiber?

Splice loss in optical fiber refers to the loss of optical power that occurs when two optical fibers are joined together through a splice. This loss can arise from misalignment, the quality of the splice, and the difference in core diameters or refractive indices between the fibers. Typically measured in decibels (dB), splice loss is critical for maintaining signal integrity in fiber optic communication systems. Minimizing splice loss is essential for optimizing the overall performance of optical networks.
