A system that integrates optical wireless technology with WDM passive optical network architecture is designed. At the transmitting end, the system uses optical frequency doubling technology to generate 40GHz optical millimeter-wave carrier, loading 2.5Gbit / s baseband data signal, the downlink transmission performance is good and the impact of dispersion is small; at the receiving end, using light wave reuse technology from the downlink signal Extract the upstream optical carrier, loading 2.5Gbit / s uplink baseband data signal. The optical frequency doubling technology reduces the millimeter wave generation cost and improves the practicability of the system.
