Using an electric arc to form a single long fiber by melting two optical fibers together at their end faces, a fiber optic fusion splicer is a device. The two glass fibers are joined end to end by the fusion splice or resulting joint so that from one fiber into the other, optical light signals can pass with very little loss.
Working of a fusion splicer
They need to be carefully stripped of their outer polymer jackets and coating, thoroughly cleaned, and then precisely cleaved to form perpendicular, smooth end faces before optical fibers can be fusion-spliced successfully. Each fiber is placed into a holder in the splicer’s enclosure once all of this has been completed. From this point on, the rest of the process is taken over by the fiber optic fusion splicer, which involves 3 steps:
Impurity Burn-Off: You can never be too clean when it comes to fusion splicing as the slightest trace of other impurities or dust can wreak havoc on a splice’s ability to transmit optical signals. Many fusion splicers incorporate an extra precautionary cleaning step into the process even though fibers are hand-cleaned before being inserted into the splicing device: they generate a small spark between the fiber ends before fusing to burn off any remaining dust or moisture. fiber stripper is also useful.
Alignment: to the fibers’ positions, the fusion splicer makes minute adjustments using precise and small, motors until they’re properly aligned. The fiber optic technician can view the fiber alignment during the alignment process, thanks to magnification by optical viewing scope, video camera, or power meter.
Fusion: It’s time to fuse the fiber's ends to form a permanent splice after any remaining dust and moisture have been burned off and fibers have been properly positioned. Melting the optical fiber end-faces without causing the molten glass core and fibers’ cladding to run together, the splicer emits a larger spark. Forming the final fusion splice, the melted fiber tips are then joined together. With most fiber fusion splices showing a typical optical loss of 0.1 dB or less, estimated splice-loss tests are then performed. You can buy a fiber tool kit.
