Radio-on-Fiber Transport Systems Integration With 622-Mb/s Baseband Transmission

We proposed and demonstrated an architecture by integrating radio-on-fiber transport systems and baseband (BB) transmission with the help of an injection-locking scheme. An externally modulated radio-frequency data stream and a directly modulated BB data signal are simultaneously transmitted over an 80-km single-mode fiber link. Good bit-error-rate performances were achieved in our proposed integrated systems. Such a proposed system is attractive and suitable for long-haul transmission due to its simple and cost-effective architecture.
