Fiber optic splice closure is a critical element in fiber optic networks as it enables the connection and protection of fiber optic cables. It ensures that the spliced fibers are securely housed and protected from environmental factors such as moisture, dust, and temperature. Fiber optic splicing is the process of joining two optical fibers end-to-end. Whether repairing a broken cable or extending a fiber run, fiber optic splicing ensures light signals travel. Infield installations, splicing is a faster and more efficient method and is used to restore fiber optic cables when a buried cable is accidentally severed. There are 2 methods of splicing, mechanical or fusion.
