ABSTRACT:
A wavelength dispersion probing system for determining a value of wavelength dispersion and its sign and reducing the trouble and time required for this determination. This wavelength dispersion probing system comprises light sources10, 12, light attenuators14, 16, optical multiplexer18, phase modulator20, optical amplifiers22, 26, acoustooptical modulator24, optical receiver30. The intensity ratio of two wavelengths is set at 1 to 2 to detect Stokes light or anti-Stokes light included in the return light of an optical fiber100by the optical receiver30, so that wavelength dispersion is probed. The wavelength dispersion is probed by changing the intensity ratio of the two wavelengths to observe the state of the change of the wavelength dispersion, so that the sign of wavelength dispersion is determined by the optical receiver30.
