Document Type and Number:

Japanese Patent JP4234927

Kind Code:

B2

Abstract:

The present invention provides an optical wavelength multiplexing transmission apparatus and an optical output control method for an optical wavelength multiplexing transmission apparatus in an optical wavelength multiplexing transmission system using a main signal light and an OSC light. The optical wavelength multiplexing transmission apparatus ( 10 a) is made up of a first transmitting/receiving section ( 52 a) a second transmitting/receiving section ( 52 b) and an apparatus supervisory control unit ( 54 ). This can not only achieve quick restoration from troubles, but also stably calculate an optical output level even if a change of the number of wavelengths to be multiplexed takes place in a main signal light, and even save troublesome adjustments for the improvement of reliability of a transmission line while eliminating the need for a signal source for the adjustment of a receive optical level at the initial installation.
