Abstract
A wavelength division and time division hybrid multiplexing passive optical network system, terminals and a signal transmission method are disclosed in the present invention. The system comprises: a plurality of optical modules at the optical line terminal side connecting to an office all-optical wavelength conversion unit, the all-optical wavelength conversion unit connecting with a subscriber all-optical wavelength conversion unit via a fiber, and the subscriber all-optical wavelength conversion unit connecting with a plurality of optical couplers, and each optical couplers connecting with a plurality of optical network units respectively; the present invention facilitates full use of the existing source of access network and ensures a smooth transition from the time division multiplexing passive optical network to the optical access network of the next generation without changing the structure of the current time division passive optical network.
