AUTOMATIC POWER TESTING METHOD AND FIRST ROADM STATION

摘要

Embodiments of the present invention provide an automatic power testing and tuning method and a first reconfigurable optical add/drop multiplexer ROADM site to improve signal receiving quality. The method includes: creating an optical cross-connection for a wavelength of a first service after receiving a first service request message, and then obtaining a deterioration balance value of a first optical signal-to-noise ratio of wavelengths of all services on the first optical multiplex section according to a current optical signal-to-noise ratio of the wavelengths of all the services on the first ROADM site and an optical signal-to-noise ratio on a next ROADM site, where the services pass through the first optical multiplex section; obtaining a first outbound target power of the wavelengths of all the services on the first ROADM site separately according to the obtained deterioration balance value of the first optical signal-to-noise ratio of the wavelengths of all the services on the first optical multiplex section; and finally, tuning a single-wavelength attenuation of the wavelengths of all the services according to the first outbound target power. The present invention is applicable to the communication field.
