The utility model provides an optical switching node means based on optical divider and wavelength division multiplexer parallel, optical switching node means includes wavelength division multiplexer and each optical divider of N, N >= 1, optical divider connects merging cells, exports after receiving the signal processing of different wavelength wavelength division multiplexer, protection device and measurement and control device. The utility model provides an exchange node means on the basis of the multicast function that realizes the sampled value business datum, greatly reduced exchange node cost, overcome the data race problem that exists among the current ethernet switch through the node structure of design, can not produce data blockage, the phenomenon of lining up, reduced transmission delay.
