A light pulse compression reflector apparatus, comprising: a single wavelength continuous light source (1), an optical splitter (2), a frequency modulation pulse generating module (3), an optical directional coupler (5), an optical fibre to be detected (6), an optical coupler (9), a balancing photoelectrical detector (10), and a pulse compression processing module (11). The conflicting relationship between the spatial resolution of traditional optical time domain reflectometry and detection range is broken, exhibiting the ultra-high spatial resolution of frequency modulation technology, and the detection range is higher than that of optical time domain reflectometry.
