Abstract
An optical pulse compression reflectometer is provided, which comprises: a single wavelength continuous optical source, an optical splitter, a modulation frequency pulse generating module, an optical directional coupler, an optical fiber under test, an optical coupler, a balanced photoelectric detector, and a pulse compression processing module. The present invention, in addition to overcoming the contradictory constraint between spatial resolution and measurement range in traditional time domain reflectometry and giving to full play the super spatial resolution from frequency modulation technology, has a longer measurement range than that in the optical frequency domain reflectometry.
