What does the term "splice" refer to in fiber optics?

The term "splice" in fiber optics specifically refers to the joining of two fiber cables. This process involves carefully aligning the fibers and then fusing them together, allowing light to pass smoothly from one fiber to another without substantial loss of signal. Splicing is essential in extending fiber optic networks, repairing breaks, or connecting different segments.

Successful splicing requires precision to ensure the core of each fiber is properly aligned and that the protective cladding remains intact. This minimizes signal loss and preserves the integrity of the data being transmitted through the fibers. Techniques for splicing include fusion splicing, where heat is used to meld the fibers together, and mechanical splicing, which holds the fibers in position using a matching fixture and adhesive.

Understanding this term is crucial for anyone working with fiber optics, as splicing plays a vital role in maintaining the performance and reliability of optical networks.
