Abstract :
We have demonstrated optical OFDM signal generation by an optical phase modulator and applied it in a 40 GHz ROF symmetric system. The power penalty for the downlink data after transmission over 50 km SMF is smaller than 0.5 dB; while for the up-link data, the power penalty can be neglected.
