Method for measuring distribution of zero dispersion wavelengths in an optical fiber and apparatus therefor |
摘要 |
In the method of measuring a distribution of zero dispersion wavelengths in an optical fiber in a longitudinal direction, an optical pulse and a pump light are launched into the optical fiber. A gain generation portion of the optical fiber which indicates that the optical pulse power is amplified based on modulation instability induced by the pump light is detected from a back-scattered light waveform of the optical pulse indicative of an optical pulse power distribution in the longitudinal direction of the optical fiber. A zero dispersion wavelength of the gain generation portion of the optical fiber is determined from the pump light wavelength.
