摘要： The present invention provides optical compensation for a submarine optical cable optical. A dummy light module generates a dummy light signal according to a continuous spectrum in a predetermined range and a combining module combines a service signal with the dummy light signal. When the dummy light is used for the compensation, conventional problems are solved, including complicated control, difficult realization of the pre-equalization function and inflexible configuration. When service signals are increased, the adjustment for the power of the dummy light signal is avoided; therefore, the control for the dummy light is simplified. In the pre-equalization operation, power control is only performed on the dummy light signal in the single channel or the continuous dummy light signal; therefore, the realization of the pre-equalization function is easy.

摘要： A method for laser safety protection in an optical communication system includes: a downstream station detecting whether an identification signal loaded by an upstream station on a main optical channel in a direction from the upstream station to the downstream station, exist on the main optical channel; if the identification signal is not detected, the downstream station executing a scheduled safety protection procedure. Methods for loading an identification signal on a main optical channel in an optical communication system and an optical amplifier of laser safety protection, which implement loading the identification signal by controlling the change of pump light of optical amplifier or the wave motion of signal light of main optical channel, are also provided. The solution makes it possible to reliably detect a fiber failure when RAMAN amplifiers or remotely-pumped amplifiers exist, thereby implementing laser safety protection.

摘要： An upgrading method, a system, and an apparatus of a low-density wavelength division multiplexing (WDM) system are provided. The method includes: detecting an output wavelength shift of a wavelength conversion unit, and adjusting an output wavelength of the wavelength conversion unit having the output wavelength shift higher than a threshold, so that the output wavelength shift of the wavelength conversion unit is lower than the threshold; adjusting an adjustable interleaved demultiplexer, until requirements for a demultiplexing parameter of a high-density WDM system are met. Thus, the problem that services are interrupted when a low-density MDM system is upgraded to a high-density MDM system is solved. A WDM system, and a wavelength multiplexing/demultiplexing apparatus and method are also provided.
