Product Application
50/125μm OM3 fiber is a graded-index multimode type featuring a 50μm core diameter and a 125μm cladding diameter.
It is comprehensively optimized Vertical-Cavity Surface-Emitting Laser (VCSEL) at the 850nn wavelength on the basis of OM2 fiber, and passes Differential Modal Delay (DMD) test so as to attain the higher bandwidth and lower attenuation, and realize short distance high data rate transmission (OM3 fiber in support of 10GBase-SR 300m, 40GBase-SR4 and 100GBase-SR10 100m).
The fiber is suitable for different structures of fiber optic cables, such as ribbon fiber cable, stranded loose tube cable, slotted core fiber cable, central-tube fiber optic cable, tight buffered fiber optic cable, etc., and it is compatible with other fibers that use different manufacturing technologies.
Product Features
The fiber is ideal for 850nn and 1300nm operating wavelengths; it optimizes Vertical-Cavity Surface-Emitting Laser (VCSEL) with low attenuation and high bandwidth; its coating protection and glass property enjoys excellent performance.
