Improvement of Spatial Resolution of the Phase Compensated Reflectometer by Correcting VCF Characteristics

Abstract

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.
