Self-phase modulation-based multiple carrier generation for radio over fiber duplex baseband communication

摘要

A self-phase modulation-based duplex baseband radio over fiber architecture is proposed, where data are transmitted up to six radio access units (RAUs) in distributed antenna system. Bidirectional full duplex 768 Mbps data transmission has been demonstrated, where data are transmitted from control unit to the base station (BS) and from BS to the RAUs over a distance of 20 km and 300 m, respectively. Our proposed architecture gives good performance and cost-effective solution for duplex RoF communication over long distance.
