•Leading 2026 models include the Fujikura 90S+, COMWAY C10S v2, Sumitomo Type-82C+, TEKCN TC-600, and JETFIBER H5—each tailored to specific use cases, budgets, and fiber types. Overview: A fiber fusion splicer is a device used to join two optical fibers end-to-end using an electric arc. The device aligns the core and cladding of the fibers so that they can be fused together. Perfect for professionals needing precise splices with core alignment technology, built-in power meter, and VFL for assessing fiber link. Modern fiber optic fusion splicers have evolved from simple splicing tools into comprehensive workstations integrating various diagnostic and testing functions.
