Embodiment Construction

[0056] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0057] According to the application of the wavelength label technology in the wavelength division multiplexing system, the present invention proposes a VMUX (Optical Channel Power Variable Multiplex, optical path power adjustable multiplexer) component using a high-speed VOA (Variable Optical Attenuator, adjustable optical attenuator) Implement wavelength labeling technology. The wavelength label information is converted into a wavelength label signal after any modulation method such as frequency modulation, amplitude modulation, or modulation. The loading of the wavelength ...

Abstract

The invention discloses a wavelength label loading method, which comprises the following steps of: generating a wavelength label signal of each optical channel; generating a control command according to the wavelength label signals, and transmitting the control command to an optical channel power variable multiplexer (VMUX) part; and regulating the light intensity of each optical channel of the VMUX part according to the control command by using the VMUX part. The invention also provides a wavelength label loading device. A wavelength label management function is added to a wavelength division multiplexing system under the conditions of no change in the conventional system structure, no increase of number of the conventional system interfaces and no increase of additional optical device cost.

Description

technical field [0001] The invention relates to optical communication technology, more specifically, to a wavelength label loading method and device in an optical communication system. Background technique [0002] The wavelength label technology is to superimpose the low-frequency tuning signal on the wavelength in the optical network, and at the same time identify the tuning signal in the optical channel on each node in the network. By deciphering the information carried in the tuning signal, the optical signal is obtained. Information about transmission paths and other wavelength channels in the network. [0003] For wavelength tag technology, please refer to Appendix D of China Post and Telecommunications Industry Standard YD / T 2003-2009 "Technical Requirements for Reconfigurable Optical Add-Drop Multiplexing (ROADM) Equipment", which introduces ROADM (Reconfigurable Optical Add-Drop Multiplexer, reconfigurable Wavelength trace monitoring (wavelength tag) technology in ...
