ABSTRACT:
Apparatus for measuring the dispersion and dispersion parameter of an optical fiber as a function of distance (the dispersion map) by the optical-time-domain reflection technique uses a multi-frequency laser with an extra cavity semiconductor optical amplifier switch to generate the short pulses of two wavelengths to displace the four-wave mixing oscillations away from the origin of the complex plane. Additionally laser power is supplied at both ends of the fiber under test to provide pump power to Raman amplify the backscattered signal being measured. Finally a novel Fast Fourier Transform based algorithm is used to calculate the dispersion map fast and accurately.
