Graded Index Multi-mode Fibre
The YOFC glass-cladding graded index multi-mode fibre (GIMM) features graded index distribution, optimized optical characteristics at the 850nm and 1300nm operating wavelengths, very low attenuation, and extremely high bandwidth. This series of GIMM features different core diameters, cladding diameters, and NAs, and can be customized to suit various applications to the greatest extent according to customer requirements.
YOFC optical fibres are manufactured using the advanced PCVD process. The PCVD process features precise deposition control, enabling perfect implementation of the preset waveguide refractive index profile. The optical fibres manufactured using the PCVD process exhibit excellent geometrical, optical, environmental, and mechanical characteristics.
