20090141267 | OPTICAL-FIBER-CHARACTERISTIC MEASURING APPARATUS AND OPTICAL-FIBER-CHARACTERISTIC MEASURING METHOD - A measurement range is extended while maintaining the spatial resolution high by completely separating the increment of a probe light from noises. Modulations are performed on both probe light and pump light to differentiate both lights. Using the modulations, only the change in the probe light necessary for measuring the characteristic of a measurement-target optical fiber FUT can be separated. Accordingly, unlike the conventional technology, an optical wavelength filter becomes unnecessary. Further, in a case where an amplitude Δf of the frequency modulation of a light source | 06-04-2009 |
