Abstract

A 1-km length of low-loss multimode optical fiber made by Corning Glass Works was excited by the pulsed output of a GaAs LED. The pulses were 3.6 nsec wide and had a spectral width of 460 A. After traveling through the fiber, the pulse had a half-power width of 6 nsec, of which 4.2 nsec was estimated to be due to material dispersion.

摘要

康宁玻璃厂制造的一段1公里长的低损耗多模光纤，由砷化镓发光二极管的脉冲输出激发。脉冲宽度为3.6纳秒，光谱宽度为460埃。在光纤中传输后，脉冲的半功率宽度为6纳秒，其中4.2纳秒估计是由材料色散引起的。
