Fiber optic network construction and maintenance require precise tools that ensure reliable connections. Our optical fusion splicer is designed for easy operation and supports splicing for a variety of fibers, including bare fibers, jumpers, and rubber-coated fibers. The spliced fibers deliver exceptional performance, with a typical return loss exceeding 60dB and minimal splicing losses. For example, multimode fibers achieve typical splicing losses as low as 0.01dB, while single-mode fibers reach losses as low as 0.02dB. These outstanding results enhance network stability and ensure efficient signal transmission across the fiber optic network.
