【摘要】 光纤中的偏振模色散ＰＭＤ（ＰｏｌａｒｉｚａｔｉｏｎＭｏｄｅＤｉｓｐｅｒｓｉｏｎ）是限制高速光纤通信系统传输容量的极限因素，我们首次用波长扫描法在国内实现了对光纤偏振色散的测量；并对国内外多种光纤进行了测量比较，发现国产的光纤质量有待改进．更多还原

【Abstract】 Polarization mode dispersion(PMD)in fiber seriously limits high-capacity optical fiber communication system. Measurement of PMD is realized through wavelength scanning methed in China for the find time.Through comparison among many kinds of imported fibers and fibers made in China, we find that fibers made in China should be modified.更多还原
