Cost-effective radio-over-fiber systems based on VCSELs

Fiber-radio systems based on directly modulated high-speed VCSELs are investigated at both 850 nm and 1300 nm. Multimode fiber for short reach applications as well as single-mode fiber to bridge longer distances have been demonstrated to show high performance. Laser noise and linearity characterization as well as system design to achieve high spur-free dynamic range of >95 dB•Hz2/3 are discussed. A comparative study of radio signal transport solutions based on fiber or coaxial cable is presented and the long transmission distances achievable over multimode fiber links presented. A picocellular network demonstrator comprising of 14 cells with a 4 m radius to investigate networking issues was developed and key performance results are presented.
