Product Application
50/125μm OM4 fiber is a graded-index multimode type featuring a 50μm core diameter and a 125μm cladding diameter.
Compared with OM3 fiber, it is further optimized Vertical-Cavity Surface-Emitting Laser (VCSEL) at the 850nn wavelength and supports 10GBase-SR 550m, 40GBase-SR4 and 100GBase-SR10 150m.
OM4 fiber is more ideal for 40G/100G transmission, since its transmission distance increases by 50% compared to OM3. OM4 multimode fiber applies 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 with 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.
