Research on effect of Numeral Aperture on Chromatic Dispersion
摘要
研究了匹配包层型光纤的数值孔径对色散的影响
试验结果表明随着数值孔径的提高
光纤的零色散波长向长波移动
色散变化在高数值孔径比低数值孔径区域明显
纤芯尺寸对色散影响相比数值孔径影响更为明显。高数值孔径光纤在1550nm波段具有较低的色散值
更有利于降低链路的色散值
提高链路的传输速率。
Abstract
Effect of matched cladding single mode fiber NA on chromatic dispersion was studied.The results show that zero dispersion wavelength increases with NA increasing and core diameter decreasing.The core diameter is major.The dispersion is less than conventional fiber in 1550 nm waveband;it is more suitable for this band.
