METHOD AND APPARATUS FOR OPTICAL COMMUNICATION MONITORING, OPTICAL AMPLIFIER SYSTEM, METHOD OF CONTROLLING OPTICAL AMPLIFIER SYSTEM, AND OPTICAL COMMUNICATION SYSTEM |
摘要 |
This invention relates to an optical transmission monitoring apparatus or the like which has a simple structure for identifying causes of variations in the power of WDM signals. The optical transmission monitoring apparatus includes a monitoring section for setting first and second wavelength bands in a monitor wavelength band, comparing variations in the optical powers of a plurality of types of light containing different light signals which are detected from the respective wavelength bands, and identifying causes o the variations in optical power in the optical transmission path. |
