摘要： A polarization-related characteristic of an optical path is determined from a predetermined function of the mean-square of a plurality of differences between polarization-analyzed optical power parameters corresponding to pairs of wavelengths mutually spaced about a midpoint wavelength by a small optical frequency difference. At least some of the said differences correspond to wavelength pairs measured under conditions where at least one of midpoint wavelength, input state of polarization (I-SOP) or analyzed state of polarization (A-SOP) of a pair is different.

摘要： A low coherent reflectometer uses low coherent beams for measurement of refletance and refleting positions with respect to a measured optical circuit which includes a reflecting point. The low coherent beams are branched to produce measurement beams (DL) and local beams (KL), so that the measurement beams are introduced into a first optical path, which includes a dispersion shifted fiber, towards the measured optical circuit, while the local beams are introduced into a second optical path which includes a spatial optical path terminated by a reflecting mirror. Refleted measurement beams (RL) and reflected local beams are combined together to produce combined beams, which are subjected to processing and analysis.

摘要： The present invention relates to an apparatus (10) that allows to characterise or measure the chromatic dispersion in an optical fibre segment (50) by accessing a single end of the fibre itself (50) and measuring the phase shift between modulating signals of impulsive kind generated by a signal generator (12) and the same modulation signals reflected by a remote end of the fibre (51). The invention further relates to the method for measuring the chromatic dispersion of the optical fibre (50). Thanks to the invention, the apparatus (10) does not require an absolute external reference signal and allows to determine the chromatic dispersion of the fibre (50) being measured as the wavelength of the optical signals varies.

摘要： A branch section transmits optical pulses of a plurality of wavelengths successively emitted from a light source at one end of an optical fiber to be measured, and extracts reflected lights from the optical fiber. A light receiving section detects reflected lights from the branch section and outputs them as measurement data. The processing section calculates a wavelength dispersion value of the optical fiber by detecting a time of emitting the optical pulse of each of the wavelengths from the light source. In a case where the optical fiber is formed of a plurality of optical fibers connected in series by at least one connecting point, the processing section calculates wavelengths dispersion values of the respective optical fibers by detecting the time of emitting the optical pulse, a time of receiving a reflected light from the connecting point and a time of receiving a reflected light from another end of the optical fiber.
