摘要

为了准确定位光学断层,通过校正扫频器的VCF特性,提高了相位补偿反射信的空间分辨率。利用100111光纤,将66.7MHz扫频范围内的频率偏差减小到0.8mhz,实验得到3.0m的空间分辨率。

Improvement of Spatial Resolution of the Phase Compensated Reflectometer by Correcting VCF Characteristics
For the purpose of locating faults along optical tibcrs exactly, spatial resolutioii of the phase compensated reflectonleter (PCII) is improved by correcting VCF charactcristics of a sweeper. The frcyuency deviation in 66.7MHz swept width is reduced to O.Ol8MHz and the spatial resolution of 3.0m is esperinientally obtained using 100111 fibers.
