The baseband frequency characteristics and the average confinement of light to core properties of a W fiber are analyzed in conjunction with corresponding singly clad (SC) fibers under some ideal assumptions It is found that the bandwidth of a W fiber is almost equal to that of the SC fiber that has no intermediate layer and is much wider than that of the other SC fiber in which the intermediate layer extends to infinity. The average fractional power flow outside the core in a W fiber is drastically reduced in comparison with both SC fibers. Practical design considerations are deduced from a typical example.
在一些理想假设下，结合相应的单层包层（SC）光纤，分析了W光纤的基带频率特性以及光对纤芯特性的平均限制。结果发现，W光纤的带宽几乎与没有中间层的SC光纤的带宽相等，并且比中间层延伸到无穷大的其他SC光纤的带宽要宽得多。与两种SC光纤相比，W光纤纤芯外的平均分数功率流大幅降低。从一个典型例子推导出了实际设计考虑因素。
