Abstract

This Letter proposes and demonstrates a two-way lightwave subcarrier transmission system employing interleavers to deliver intensity-modulated CATV/phase-modulated RoF/intensity-remodulated 16-QAM-OFDM signals over two 20 km SMF links. To the best of our knowledge, it is the first time that interleavers have been employed in two-way lightwave subcarrier transmission systems. The downstream light is successfully intensity-remodulated with a 16-QAM-OFDM signal for uplink transmission. We obtained excellent performance from the CNR/CSO/CTB/BER for CATV/RoF/16-QAM-OFDM signal transmissions. The proposed systems offer impressive performance features to deliver hybrid CATV/RoF/16-QAM-OFDM signals.
