摘　　要：光载无线通信技术结合光纤通信和无线移动通信的技术优势,较好的解决了带宽问题,灵活性问题和电磁干扰问题,其相关技术的研究已在国内外引起了广泛关注。目前瓶颈问题是实用性低,成本较高。作者对此提出了光载无线多体制接入(RoFMA)的实现方案,提出用光时分复用、多体制复用与解复用技术降低接入成本。预示了光载无线多体制宽带接入技术必然获得较大规模发展和较好的市场前景。Radio over Fiber （RoF） communication technology combines the advantage of optical fiber communication and wireless communication, solves the problem of bandwidth, agility and electromagnetic interfere. Its research of correlation techniques has attracted wide attention both at home and abroad. At present, its bottleneck problems are low practicability and high cost. The authors put forward the realization scheme of Radio over Fiber Multi-systems Access （RoFMA） to use optical time-division multiplex, multi-systems multiplex and de-multiplex to reduce access costs, indicating that RoFMA technology will achieve large-scale development and better market prospects.
