Instead of fusing one fiber at a time, mass fusion splicing can fuse up to all 12 fibers in one ribbon at once. Many of today's cables with high fiber count involve subunits of 12 fibers each that can be quickly ribbonized. Fiber optic joints or terminations are made two ways: 1) splices which create a permanent joint between the two fibers or 2) connectors that mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear. Either joining method must have three primary characteristics. Fiber optic splicing is the process of seamlessly joining two single Splicing has a lower optical loss and back-reflection than other terminations, making it the ideal choice for maintaining signal integrity and reliability in fiber optic networks. There are numerous use cases for fiber optic splicing. Through splicing, fiber optic technicians can extend the length of the fiber to make it long enough for use in a required cable run. As. To begin, the standard definition of splicing in optical fiber is joining two fiber optic cables together. The other, more common, method of joining fibers is called termination or connectorization. Splicing is most commonly used in the field but has application in cable assembly houses.
