What does "splice" mean in the context of fiber optics?

In the context of fiber optics, "splice" specifically refers to the process of joining two optical fibers together. This is crucial for establishing a continuous path for light signals within fiber optic networks. When fibers are spliced, they must align precisely to minimize loss and maintain signal integrity. The splicing process can involve fusion splicing, where the ends of the fibers are melted together, or mechanical splicing, where they are aligned and held together with a matching gel or adhesive.

Proper splicing ensures that the light traveling through the fibers can continue uninterrupted from one fiber to another, allowing for reliable and efficient communication over distances. This aspect is essential in maintaining the quality of the signal transmitted through fiber optic cables, which is why it is a fundamental concept in the installation and maintenance of fiber optic systems.
