Abstract
A hybrid optical access configuration for simultaneously providing wired and wireless services was proposed. The proposed system can also remote deliver doubled local-oscillator signal, which can be reused in the uplink. At the central station, the signals used for wireless links are subcarrier multiplexing and modulated as PSK format, and the wired baseband signals are directly modulated as NRZ format, then two signals are simultaneously generated by an external integrated modulator and transmitted on the same wavelength. The doubled local-oscillator signal is extracted in the wireless links, then used in the uplinks, the recieved eye diagrams are pretty well.
