Special Fiber Cut-off Wavelength Sing Mode Optical Fiber
Special cut-off single-mode wavelength fiber optic is a special single-mode fiber product designed and developed for all kinds of special working band optic fiber devices. This series of cut-off wavelength optical 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.
Product Characteristics
*Cut-off Wavelength Sing Mode Optical Fiber has Low attenuation of optic fiber fusion;
* Wavelength fiber optic has low bending additional attenuation;
*Excellent geometric uniformity;
*Excellent mechanical properties;
