Abstract A broadly converged 40G-ROF and 10-Gb/s WDM-PON multi-service access system is proposed and experimentally demonstrated. This scheme consists of an integrated system of 40G-ROF and 10-Gb/s WDM-PON simultaneously transmitting independent 2.5-Gb/s wireless and 10-Gb/s wire signal. At the base station, it employs a remodulation scheme, which is achieved by remodulating the upstream OOK signal on the DPSK downstream signal, to reduce the cost of the base station. The transmission experiment is carried out over a 25-km-long single mode fiber (SMF-28). The results show that the sensitivities of downstream PON and ROF signal are −14.5 dBm and −21.5 dBm, respectively, and the sensitivity of upstream signal is−25.3 dBm.
