Product Description
Special Cut-off Wavelength SM Fibers
Our special cutoff wavelength single-mode fiber is a special single-mode fiber product designed and developed for all kinds of special working band optic fiber devices. This series of optic fiber preforms are prepared by in-tube chemical vapor deposition process, which has the advantages of low hydroxyl group, accurate geometric parameters, good optical uniformity, good bending resistance and so on. This series of optic fibers are widely used in special band optic fiber signal transmission, optic fiber sensing devices, optic fiber amplifiers, fiber lasers and so on.
