Step Index Multi-mode Fibre (SIMM)
YOFC silica-cladding multimode fibres (preforms) with step index profile are comprehensively optimized at both 850nm and 1300nm operating wavelengths. At
both wavelengths, extremely low attenuation and high bandwidth could be achieved. To satisfy the demand of client to the most extent, a series of silica-cladding step index multimode fibres can be customized with different fibre designs, including core diameter, cladding diameter, fibre diameter and NA. YOFC fibres are manufactured with the advanced Plasma Activated Chemical Vapor Deposition (PCVD) process. Due to the inherent advantages of the process, YOFC fibres have extremely precise refractive index profiles (RIPs) to provide excellent geometrical, optical, environmental and mechanical properties.
