Direct optical switching code-division multiple-access system for fiber-optic radio highway networks

Recently, microwave photonics techniques have significantly progressed to realize a new type of communication system enhancing the synergetic effect of wireless easy access and photonic broadbandness. This paper describes the concept of radio highway networks configured by radio on fiber links, which are transparent for various types of radio formats. Also as an effective candidate for a multiple-access method of radio signal into the radio highway network, this paper reports direct optical switching code-division multiple-access system and shows its performance theoretically and experimentally.
