METHOD FOR MONITORING VARIATION OF WAVELENGTH DISPERSION, SYSTEM FOR MONITORING VARIATION OF WAVELENGTH DISPERSION AND SYSTEM FOR COMPENSATING WAVELENGTH DISPERSION |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a dispersion monitor that directly monitors a dispersion variation by a simple configuration and is inexpensive. <P>SOLUTION: A method for monitoring the variation of wavelength dispersion detects the variation of wavelength dispersion according to a reaction of a light receiving element by using a dispersion variation monitor 46 that is the light receiving element that generates the reaction according to a plurality of photons 42, 44 in a wavelength band of an optical signal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
