The bandwidth of multimode W-type plastic optical fibers (POFs) with graded-index (GI) core distribution is investigated by solving the time-dependent power flow equation. The multimode W-type GI POF is designed from a multimode single-clad (SC) GI POF fiber upon modification of the cladding layer of the latter. Results show how the bandwidth in W-type GI POFs can be enhanced by increasing the wavelength for different widths of the intermediate layer and refractive indices of the outer cladding. These fibers are characterized according to their apparent efficiency to reduce modal dispersion and increase bandwidth.
通过求解含时功率流方程，研究了具有渐变折射率（GI）纤芯分布的多模W型塑料光纤（POF）的带宽。多模W型GI POF是在对多模单包层（SC）GI POF光纤的包层进行改性后设计而成的。结果表明，对于不同宽度的中间层和外包层折射率，如何通过增加波长来提高W型GI POF的带宽。这些光纤根据其降低模式色散和增加带宽的表观效率进行表征。
