Performance analysis of direct optical switching CDMA Cable-To-The-Air network

For Cable-To-The-Air network providing a seamless access network in both indoor and outdoor, direct optical switching CDMA scheme is newly proposed to multiplex any types of radio signals for two types of bus link such as optical switch connection and optical coupler connection. It is clarified that in the optical switch connection system, by introducing the additional optical gain at each radio base station, the performance can be improved compared with the optical coupler connection system.
