Glass Clad Step-index Multimode Special Fiber Optic

Glass clad step-index multimode special fiber optic has a gradient step-index refractive index distribution. The optical properties of the 850nm and 1300nm windows fully optimized, with very low attenuation. This series of glass clad step-index multimode optical fibers has different core diameters, cladding diameters and numerical apertures. Customized services can provided according to customer needs. To meet the different application needs of customers to the greatest extent. The optical fiber is manufactured using advanced plasma chemical vapor deposition (PCVD) technology. The PCVD process has precise deposition control and can perfectly realize the preset wave guide refractive index profile. Optical fibers manufactured using the PCVD process have excellent geometric, optical, environmental and mechanical properties.
