Fiber optic splice cassette wiring typically involves the following steps:
Preparation: Start by confirming the type and capacity of the fiber splice cassette to ensure that it can accommodate the number of fibers required to connect. Have a fusion splicer, wire strippers, cleaning tools, fiber cutters, fiber patch cords, and necessary auxiliary materials ready.
Fiber stripping: Use wire strippers to carefully peel off the outer sheath and waterproof layer of the fiber to be spliced to expose the bare fiber. Be careful not to damage the fiber.
Fiber cleaning: Use alcohol and dust-free paper to clean the stripped fiber endface to remove dust and impurities.
Fiber cutting: Use a fiber cutter to precisely cut the end face of the fiber to ensure that the cut is flat and vertical.
Fiber docking: Insert the fiber to be spliced into the corresponding port in the splice box and fix it with an optical fiber fixture.
Fusion splicing operation: The heating clamp of the optical fiber fusion splicer clamps the optical fiber and starts the fusion splicing procedure. The splicer automatically aligns the fiber end-face and performs heated splicing.
Check after splicing: After splicing, clean the splice point again and use an optical test instrument (such as an optical power meter) to check the optical attenuation of the splice point to ensure that the fiber is well connected.
Fiber protection: If needed, a protective sleeve or heat shrink tubing can be added at the splice point to protect the splice point from external influences.
Documentation & Identification: Record the location and related information of the splice points and properly identify the fibers for future maintenance and management.
Please note that fiber splicing is a job that requires specialized skills, and the quality of splicing directly affects the performance and stability of fiber optic networks. Therefore, in the absence of experience, it is recommended that a professional fiber engineer or technician perform the splicing work.
