A Full-Duplex Radio-Over-Fiber Transport System Based on FP Laser Diode With OBPF and Optical Circulator With Fiber Bragg Grating

A full-duplex radio-over-fiber transport system based on an Fabry-Perot laser diode (FP LD) with an optical bandpass filter at the central station, as well as employing an optical circulator with a fiber Bragg grating at the base station, is proposed and demonstrated. Good transmission performances estimated by bit-error rate and eye diagram are obtained in our proposed systems. Since our proposed systems use only an FP LD as a light source for both down-link and up-link transmissions, it reveals a prominent alternative with advantages in simplicity and cost.
