Abstract

PURPOSE:To make it possible to measure the characteristics of the transmission band of the long, single mode optical fiber by inputting high intensity, short pulses into the optical fiber. CONSTITUTION:The light beam from a YAG laser 1 is converged by a lens 2 and inputted into the long, single mode optical fiber 3 with a small diameter. The light having a specific wavelength component is taken out of the output light beam by a spectroscope 4, converged by lenses 5 and 6, and given to a photoelectric transducer 7. The transduced signal is sent to a sampling oscilloscope 8. A specified signal is sent to a data processor 9 from the oscilloscope 8, and the processed signal is supplied to an output terminal 10 and a display 11. In this case, if the high energy, short light pulses are inputted into the fiber 3, Raman scattering is generated in the fiber, and the light pulses having various wavelength are generated in the output light. Then Fourier transformation is performed on each light pulse by a device 9, and the characteristics of the band of the fiber 3 are obtained for each wavelength.
