Fujikura 70S+ SM MM Fixed V-Groove Ribbon Fiber Fusion Splicer

The Fujikura 70S+ is a core alignment fusion splicer engineered for precise splicing of single-mode, multimode, and specialty optical fibers. It delivers typical splice losses of 0.02 dB (SM), 0.01 dB (MM), and 0.04 dB (DS/NZDS) with return loss exceeding 60 dB, measured via cut-back methodology to ITU-T and IEC standards. The fixed V-groove alignment system accommodates cladding diameters from 80 µm to 150 µm and coating diameters up to 3,000 µm, with cleave lengths of 5 mm to 16 mm.
