Abstract :
The transmission of 64 QAM radio data signals with a data rate up to 150 Mb/s through long single mode fiber links at different frequencies has been experimentally evaluated. The system under study uses the optical frequency multiplication technique for the generation of carriers in the microwave and millimeter-wave bands. Transmission using frequencies of 18.7 GHz, 19.5 GHz, 19.7 GHz and 29 GHz is demonstrated for fiber links up to 125 km, and up to 100 km for transmission frequencies of 32.5 GHz and 36.9 GHz. A careful adjustment of the filter characteristics is crucial to fulfill the performance requirements.
