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 850 nm wavelength and supports 10GBase-SR 550m, 40GBase-SR4, and 100GBase-SR10 150m.


OM4 fiber is 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 850 nn and 1300nm operating wavelengths. It optimizes Vertical Cavity Surface-Emitting Laser (VCSEL) with low attenuation and high bandwidth. Its coating protection and glass property enjoy excellent performance.
