Tunnel splicing of optical cables
This method is a simple device designed to accurately align two ends of an optical fiber with a mechanical assembly so light can pass from one end to the other. The fibers formed by this type of splicing are not permanently attached but are held in the exact position. Use and Maintain Your. Fiber optic cable splicing involves joining two fiber optic cables together. Another method of connecting optical fibers is termination or connectorization, which consists of processing the end of a fiber optic bundle so that it can be connected to other fibers or devices through fiber optic. Fusion splicing is both an art and a science. Done right, it produces connections with less than 0. 1dB loss that will last the life of the cable plant. The performance of a fiber optic splice is determined by a number of factors, including the quality of the fiber, the cleanliness of the splice, and the techniques used to make the splice.
