Network structure based on rotating array waveguide grating device

Abstract

An embodiment of the application discloses a network structure based on a rotating array waveguide grating device to solve the problem of too many jumpers among capacity expanding sets of a fully connected network structure so as to substantially reduce the number of optical fibers interconnected among the sets. The network structure based on the rotating array waveguide grating network according to the embodiment of the application includes at least two rotating array waveguide grating devices and a plurality of switches. Each rotating array waveguide grating device is connected with at least one other rotating array waveguide grating device through an interconnecting port. Other ports, other than the interconnecting port, of the at least two rotating waveguide grating devices are connected with any one of the plurality of the switches separately. The input port is for acquiring an optical signal from the connected switch. The output port is for transmitting the optical signal to the connected switch.

Description

technical field [0001] The present application relates to the field of computer communication, in particular to a network structure based on rotating arrayed waveguide grating devices. Background technique [0002] All-optical horizontal expansion fully connected data center network architecture (scale out data communication network, Scale Out DCN), when receiving the signal sent by the source server through the first switch with wavelength division multiplexing function, the signal is modulated by wavelength division multiplexing technology the optical signal of the corresponding wavelength; send the successfully modulated optical signal to the array waveguide grating (array waveguide grating, AWG); The optical signal is sent to the second switch connected to the destination server; the second switch converts the received optical signal into an electrical signal and sends it to the destination server. Such as Figure 1a As shown, the all-optical Scale Out DCN structure is ...
