Embodiment Construction

[0065] The embodiment of the present application provides a reconfigurable optical add / drop multiplexer, which can improve the performance of the add / drop module.

[0066] First, combine figure 1 The architecture of the reconfigurable optical add-drop multiplexer is introduced. The reconfigurable optical add / drop multiplexer includes a 1*K wavelength selective switch (Wavelength Selective Switch, WSS) on the line side and an add / drop module on the client side, and the add / drop module is connected to the wavelength selective switch; figure 1 In , the add / drop module is an M*N wavelength selective switch, which is used to download or upload signals; where 1, K, M and N all represent the number of ports.

[0067] Based on the downloading signal of the wave adding and adding modules, the wavelength selection switch will first receive the signal from the line side, and then transmit the received signal to the wave adding and adding module, and finally the wave adding and adding mo...

Abstract

The embodiment of the invention discloses a reconfigurable optical add-drop multiplexer which is used for improving the performance of an up-down wave module. The reconfigurable optical add-drop multiplexer comprises optical fibers, X first wavelength selection switches and Y up-down wave modules, wherein the X first wavelength selection switches correspond to W directions; both X and W are integers greater than 1; the W directions comprise a first direction and a second direction; the first direction corresponds to P first wavelength selection switches in the X first wavelength selection switches, and P is an integer greater than 1; the second direction corresponds to Q first wavelength selection switches in the X first wavelength selection switches, and P+Q is smaller than or equal to X; the first up-down wave module is connected with A of the P first wavelength selection switches through the optical fibers and connected with B of the Q first wavelength selection switches through the optical fibers, the first up-down wave module is one of the Y up-down wave modules, A is a positive integer smaller than P, and B is a positive integer smaller than or equal to Q.

Description

technical field [0001] The embodiment of the present application relates to the technical field of communications, and in particular to a reconfigurable optical add-drop multiplexer. Background technique [0002] Reconfigurable Optical Add-Drop Multiplexer (Reconfigurable Optical Add-Drop Multiplexer, ROADM) is a node device of an optical fiber communication network. The flexibility of scheduling optical signals by a multiplexing (Wavelength Division Multiplexing, WDM) network. [0003] At present, the ROADM is mainly composed of a wavelength selective switch (Wavelength Selective Switch, WSS), and the WSS selects and schedules optical signals according to wavelengths. Such as figure 1 As shown, in the existing ROADM, any M*N WSS serving as an add / drop module is connected to any 1*K WSS in any direction. [0004] Therefore, as K increases, the port number M of M*N WSS will increase sharply, thereby reducing the performance of M*N WSS. Contents of the invention [0005]...
