Problems solved by technology

However, none of the above-mentioned optical switches is a multi-granularity optical switch that supports automatic switching optical network functions. In the "Draft Optical Multi-Granularity Structure Framework" submitted by Alcatel of France, only a conceptual structure of multi-granularity is given. no specific implementation
At present, several domestic companies such as Huawei and ZTE are engaged in the follow-up research and development of optical switches similar to the above-mentioned foreign companies, but there is no report on the research results of similar label-based multi-granularity optical switches.

Embodiment Construction

[0032] Such as image 3 Shown is a schematic diagram of an example of the multi-granularity optical switch structure of the present invention. Among them, the number of input and output fibers L=4, the number of wavelengths per fiber N=4, can realize 4×4 fiber switching; P=2, M=2, can realize the switching of PM=4 wavelength groups; I=2, The exchange of N(L-I)=4×(4-2)=8 wavelengths can be realized. And there are Q=8, Q-M(L-I)=8-2×2=4 wavelengths or [(Q-M(L-I)] / M=4 / 2=2 wavelength groups add and drop.

[0033] The specific structure is as image 3 As shown, the label-based multi-granularity optical switch is composed of a multi-granularity optical switch module, an electrical controller 9 and a signaling agent 10 . The multi-granularity optical switching module is composed of two-stage optical switches (2 and 5), a wavelength division multiplexer 3, and a wavelength division multiplexer 8. The first-stage optical switch 2 is a 4×4 optical switch, the input is four optical fi...

Abstract

The present invention discloses a multi-granularity optical switches based on markers. It is composed of the multiple granularity optical exchanging module, a electric controller and a signaling agency. The said optical exhanging module consists of the optical switches in two stages, the wave decomposition multiplexers and the wavelength division multiplexers. L lines of optical fiber are input to the LXL optical switches, and I lines of the optical fiber in the output do not pass through the wave decomposition multiplexer. (L-I) fibers are connected to (1XN) wave decomposition multiplexer. The N wavelengths outputted by each wave decomposition multiplexer are divided into P wave bands or wavelength groups, which are inputted to P entries of QXQ optical switches, with M wavelengths in one group. The P wave bands or wavelength groups outputted by the QXQ optical switches are connected to (L-I) entries of (NXI) wavelength division multiplexers.

Description

Technical field: [0001] The invention belongs to the technical field of information network and the technical field of optical fiber communication. Background technique: [0002] In modern society, people's demand for various media information including voice, data, video, etc. is increasing day by day, which makes the communication traffic grow extremely fast in recent years, especially the traffic of data services represented by Internet services is 2-3 times of Moore's law Regular growth has brought enormous pressure to the telecommunications network. With the advancement of information technology, the integration of the three networks of telecommunication network, computer network and radio and television network is becoming a major trend in the development of telecommunication. With its outstanding advantages of wide bandwidth and low transmission loss, optical fiber has become an ideal transmission medium for backbone networks, metropolitan area networks, and even acc...
