The result shows that:(1)Micro-fibril angle increases gradually from the center to the edge in radial direction, and the surface area percentage of its fiber band has the same variability;

结果表明，微纤丝角径向自内向外略有减小，纤维股面积比径向自内向外逐渐增大；

Becouse multimode fiber has high modal dispersion which limits to its bandwidth distance product, the band pass characteristics of the multimode fiber was analyzed.

多模光纤存在严重的模式色散，其带宽距离积受限。为此，分析了多模光纤的带通特性。

While the professors have made quite a stir in the press, Corning points out that the fiber produced by the professors has not come up to the quality of the existing Corning fiber--inferior in the important broad band qualities needed for carrying the varied communications of the future.

Although the Ka-band service's 4Mbps downstream and 1Mbps upstream speeds won't have anyone dropping their 330Mbps fiber anytime soon, the pay-as-you-go strategy will let travelers and rural dwellers get broadband in a pinch, no matter how spotty terrestrial access might get.
