The invention provides a novel technical scheme of wavelength division multiplexing passive optical network. This scheme considers the downlink growing user downlink bandwidth demand and high-speed Internet business of non symmetry, using the multi wavelength in the downlink and uplink downlink signal to carry keep single wavelength for carrying the uplink signal. The technical scheme of the invention can improve the overall downlink bandwidth of the PON system, the technology and the frame format design of access control and can use a large number of existing technology, the technical scheme of the invention can be compatible with the existing terminals in passive optical network. The technical scheme of the invention is a high speed passive optical network is an economical solution, especially when applied to upgrade the existing passive optical network, which can effectively protect the operator or user upfront investment, reduce the cost of construction or use.
