A Full-Duplex Radio-on-Photonic Crystal Fiber Transport System

A full-duplex radio-on-fiber transport system based on wavelength-division-multiplexing and optical add-drop multiplexing techniques, as well as proper length of photonic crystal fiber (PCF) is proposed and demonstrated. Over a combination of single-mode fiber and PCF transmission, low third-order intermodulation-distortion-to-carrier ratio (IMD3/C) and bit-error-rate values were obtained in our proposed systems. Such a proposed full-duplex radio-on-PCF system is suitable for the long-haul microwave optical links
