What is a splice, in terms of fiber optics?

A splice, in the context of fiber optics, refers to a permanent join between two fiber optic cables. This process is crucial for maintaining the integrity of the light signal transmitted through the fibers. When two fiber optic cables are spliced together, it involves carefully aligning the optical fibers to ensure minimal loss of signal strength and clarity.

This joining can be achieved through various methods, such as fusion splicing or mechanical splicing. Fusion splicing uses heat to melt the ends of the fiber together, creating a seamless connection, while mechanical splicing aligns the fibers using a specialized fixture and adhesive. Both methods aim to create a long-lasting bond that optimizes signal transmission and minimizes disruption.

Unlike a temporary join between cables, which may be used for quick fixes or testing purposes, splicing is a definitive action intended for established network configurations requiring reliability. This characteristic distinguishes it from other options like methods for connecting copper wires or types of connectors, which serve different functions in cabling systems.
