Product Description
Product Introduction
Special cutoff wavelength single-mode fiber is a specialized single-mode fiber product designed and developed specifically for fiber devices operating in special frequency bands. The preparation of this series of fiber preform rods adopts the chemical vapor deposition process inside the tube, which has the advantages of low hydroxyl groups, accurate geometric parameters, good optical uniformity, and good bending resistance. This series of optical fibers is widely used for fiber signal transmission in special frequency bands, fiber sensing devices, fiber amplifiers, fiber lasers, etc.
