During the actual operation of fiber cables, fiber optic splicing is often needed to achieve the connection between optic fibers. To be specific, fiber optic splicing is a process to combine the ends of optic fibers together. And only one end of each individual fiber is required. There are mainly two types splicing methods: the mechanical splicing and the fusion splicing. The article will introduce these two splicing methods and their particular steps of splicing. Fiber Closure is usually used with outdoor fiber optic cables, provides space for the outdoor fiber optic cables to be spliced together. The fiber optic splice closures and the fiber trays inside will protect the spliced fiber and the joint parts of the outdoor fiber cables. Generally the fiber optic splice closures are dome fiber closure, and inline closure is used more often.
What Is Mechanical Splicing?
Mechanical splicing is using the alignment devices to hold two fiber ends in a precisely aligned position. This enables the light to pass freely through one fiber to another fiber. In this method, the joint is not permanent. Two fibers can still be split after the signal transmission. Mechanical splicing has a low initial investment but costs more for each splice.
Four Steps of Mechanical Splicing:
1. You need to prepare the fiber by peeling off the outer coatings, jackets, tubes, etc. to just expose the bare fiber. And you much keep the cleanliness of fiber in case of failing the later transmission.
2. You need to cleave the fiber.
3. You need to joint the fibers mechanically with no heat. Just connecting the ends of fiber together inside the mechanical splice unit and the device will help couple the light between two fibers.
4. You need to protect the fiber during the light transmission. Typically, the completed mechanical has its own protection for the splice.
