ABSTRACT:
An optical time domain reflectometry system is used to determine a power response from a device under test -DUT-. For providing power information data, an optical transmitter launches a probe signal with a first wavelength into a DUT, an optical receiver determines optical power information of a first return signal returning from the DUT at a second wavelength, wherein the second wavelength is not equal to the first wavelength, and an analyzer analyzes the power information determined by the optical receiver, and generating data to be at least one of: visualized, stored, and further processed.
