What does "splice" mean in fiber optics?

In the context of fiber optics, "splice" refers specifically to the process of joining two optical fibers end-to-end. This is typically done to create a continuous optical path, allowing signals to pass through without significant loss. The splicing process can involve either fusion splicing, where the fibers are melted together using heat, or mechanical splicing, where the fibers are aligned and held together using a special fixture.

This connection is critical in fiber optic installations, as it directly affects signal quality and overall network performance. A well-executed splice minimizes any loss of light or signal degradation between the fibers, which is essential for maintaining the integrity of the data being transmitted. Proper splicing techniques ensure that the optical fibers are precisely aligned, allowing for efficient coupling of light between the two ends.
