Simultaneous provision of wired service and dispersion-robust 60GHz wireless service in radio-over-fiber system based on remote-up conversion with electrical tones injection

A novel and simple remote up conversion (RUC) scheme is proposed to provide wired service and 60 GHz dispersion-robust wireless service in a radio-over-fiber (RoF) system based on electrical tones injection (ETI). According to our knowledge, the RUC scheme with only one modulator is proposed for the first time. The ETI is utilized to simplify the traditional RUC scheme by simultaneously using one modulator for both the modulation of baseband data millimeter wave. Moreover, such scheme can provide both wired and wireless service without any additional device. Experimental results show that 2.5 Gbps wired service and 2.5 Gbps wireless service at 60 GHz are successfully delivered over 50 km SMF with power penalty less than 0.3 dB.
