Cross-connect device for optical networks

摘要

A cross-connect device for networks is connected to working transmission lines and reserve transmission lines, and is used to switch signals from the input transmission lines to the output transmission lines. The cross-connect device consists of a routing component and bypass component. The routing component is connected to the working transmission lines and is used to switch the signals from the input working transmission lines and second links to the output working transmission lines and first links. The bypass component is connected to the reserve transmission lines and is used to switch the signals from the input reserve transmission lines and first links to the output reserve transmission lines and second links. An optical cross-connect device for optical networks is connected to reserve optical transmission lines and working optical transmission lines, and is used to switch wavelength multiplexed optical signals. The optical cross-connect device comprises: a bypass component that is connected to the reserve optical transmission lines and that includes an optical-space switch; a routing component that is connected to the working optical transmission lines and includes an optical-space switch; and connection links that connect the bypass component and routing component. <IMAGE>
