The invention discloses a method and a 
system for supporting multi-service intelligent access based on the 
radio over fiber technology. The method comprises the following steps: the network side adopts an OFDM modulation technology to convert multiple service 
baseband signals from multiple operators to OFDM modulated 
baseband signals, and recombine the services to a plurality of multi-service scene groups according to a service deployment strategy; the 
radio over fiber technology is adopted to convert the OFDM modulated 
baseband signals to optical 
millimeter wave signals to be transmitted on a single 
optical fiber cable; the user side performs 
photoelectric conversion to the optical 
millimeter wave signals and respectively provides a 60 GHz all-service access mode and an intelligent multi-service scene access mode. By virtue of the method and the 
system, multiple services of multiple operators can be efficiently transmitted on the single 
optical fiber cable; furthermore, the services can be recombined, dispatched and selected according to different service deployment requirements, so as to reduce the total service access cost, simplify the equipment at the user side, improve the anti-jamming capability, the flexibility and the expandability of the 
system, and promote the user experience.
