Claim:
1. An optical pulse compression reflectometer, comprising a single wavelength continuous optical source, an optical splitter, a modulation frequency pulse generator, an optical directional coupler, an optical fiber under test, an optical coupler, a balanced photoelectric detector photodetector, and a pulse compression processor; wherein an output port of said single wavelength continuous optical source is connected with an input port of said optical splitter, a first output port of the optical splitter is connected with a first port of the optical directional coupler en route of the modulation frequency pulse generator, a second port of the optical directional coupler is connected with said optical fiber under test, a third port of the optical directional coupler is connected with a first input port of the optical coupler, and a second output port of the optical splitter is connected with a second input port of the optical coupler; and two branches of output of the optical coupler are received in said balanced photodetector, and an output port of the balanced photodetector is connected with said pulse compression processor.
