The invention provides a high iron 60GHz millimeter wave broadband access system and method, downlink sending module inside the system control center station device produced in the N independent light signal by multi wavelength laser, and the modulation of information, and then using WDM technology will be the same to reuse a link, the base station device for demultiplexing of N optical signals received by the base station; in each customer compartment, downlink receiving module converts the light signal into the millimeter wave RF signal containing information, and sent through the base station to impersonate the client, realize broadband downlink uplink transmission module; each base station will millimeter wave RF signal from the analog client into optical signal has been modulated information, then the optical signal multiplexing output of each base station and transmitted to the central station device, central station The upstream receiving module of the device can demodulate and demodulate the received optical signals so as to realize broadband access of the uplink.
