Abstract

The invention relates to an arrayed waveguide grating (AWG)-based multi-core multi-wave short distance interconnected network. The interconnected network comprises N upper level switches, N lower level switches and a network middle level, wherein each upper level switch and each lower level switch have N CWDM light transceiving modules, N light transceiving modules of each upper level switch are connected with n m*1 multi-core optical multiplexing modules, N light transceiving modules of each lower level switch is connected with n 1*m multi-core optical demultiplexing modules, the network middle level consists of n<2> r*r multi-core multi-wave connection line modules, and the multi-core optical multiplexing modules of the upper level, the multi-core optical demultiplexing modules of the lower level and the n<2> r*r multi-core multi-wave connection line modules of the middle level are connected through an m-core MPO-MPO optical jumper wire. The connection line complexity of the interconnected network is O(N<2> / r), a used wavelength set is Lambda={lambda0, ... , lambda<k-1>}, the network connection line complexity is lowered, a wavelength resource of a communication window is saved,and the expandability of the AWG-based interconnected network is enhanced.

Description

technical field [0001] The present invention relates to the technical field of optical interconnection network, in particular to a multi-core multi-wavelength short-distance interconnection network based on Arrayed Waveguide Grating (hereinafter referred to as AWG). Background technique [0002] With the advent of the era of big data, a large number of emerging broadband applications and information consumption have emerged, which put forward new requirements for the transmission, storage and calculation of massive information. Among them, the data center plays a pivotal role and has become the infrastructure of the information society. The explosive growth of network information is driving the scale of data centers towards super-large scale. The traditional direct port connection method between devices makes the cable connection between switches in super-large data centers very complicated. [0003] Complex and long cables can cause great difficulties in system maintenanc...
