Abstract

The invention discloses a device for power management, which is used for regulating the output power in the transmission process. The device comprises a monitoring module, a control module and a processing module, wherein the monitoring module is used for counting the distribution condition of the output power of signals with various wavelengths in the transmission process so as to obtain a counting result which comprises the output power of the signals with various wavelengths and sending the counting result to the control module; the control module is used for confirming a power control parameter according to the counting result from the monitoring module and sending the power control parameter to the processing module; and the processing module is used for regulating the gain slope of the output power according to the power control parameter from the control module. The invention also discloses a method for power management. The invention simplifies the design method of a system, lowers the construction cost of the system and increases the gain margin.

Description

technical field [0001] The present invention relates to the communication field, in particular to a power management method and device. Background technique [0002] The transmission distance in the wavelength division multiplexing (Wavelength-Division Multiplexing, referred to as WDM) long-distance transmission network is more than 1000Km. A subsystem is established for managing power of a transmission system. [0003] In the current long-distance transmission system, Erbium-doped Optical Amplifier (EDFA) has the advantages of direct optical amplification, low cost, large gain, low noise, and wide gain bandwidth, so it has been widely used. However, with the increase of the transmission distance, the output power of EDFA also increases. At present, products with an output optical power of more than 24dBm have been put into use. The direct result of the increase of the fiber-into the power is that the nonlinear effects of the fiber will increase, such as the Kerr effect, s...
