optical routing equipment

Abstract

An optical routing device, comprising: N first input terminals (I0, I1, ..., I(N-1)), M first output terminals (O0, O1, ..., O(M-1)) and a wavelength routing module (11). The wavelength routing module (11) comprises M micro-ring arrays (110, 111, ..., 11(M-1)), and each micro-ring array (110, 111, ..., 11(M-1)) comprises N second input terminals (i0, i1, ..., i(N-1) and N second output terminals (o0, o1, ..., o(N-1)); each second input terminal (i0, i1, ..., i(N-1)) of each micro-ring array (110, 111, ..., 11(M-1)) is used for receiving an optical signal input by a corresponding first input end terminal (I0, I1, ..., I(N-1)); and the N second output terminals (o0, o1, ..., o(N-1)) of each micro-ring array (110, 111, ..., 11(M-1)) are used for connecting a corresponding first output terminal (O0, O1, ..., O(M-1)). The optical routing device may support a transmission channel of any wavelength without altering hardware structure, thereby making use of the device more flexible.

Description

technical field [0001] Embodiments of the present invention relate to optical communication technology, and in particular to an optical routing device. Background technique [0002] With the popularity of applications such as interactive network television (abbreviated as IPTV) and cloud storage, Internet traffic continues to grow, and higher requirements are placed on the capacity and energy consumption of switch nodes in core networks and data centers. The bandwidth upgrade of existing electric domain switches is limited in terms of technology and energy consumption, while future interconnection technologies require high connectivity, high capacity, low latency, low power consumption, and low cost. Therefore, optical switches are regarded as important enabling devices for next-generation switching systems. [0003] At present, the integrated optical switch mainly realizes the spatial routing function. However, with the popularity of Wavelength Division Multiplexing (WDM)...

Problems solved by technology

[0004] However, since AWG devices can only support fixed-wavelength channels and cannot support flexible-grid networks, the use of the above-mentioned optical switches that use AWG to implement space-wavelength routing is limited and lacks flexibility.
