摘要
文章认为为了实现更大的光接入网容量,并能更好地完成多业务的承载与融合,亟待发展下一代光接入网技术。文章提出了基于光纤无线融合的射频无源光网络(RPON),其不仅具有现有无源光网络系统低成本和易管控的特点,还具备光载射频系统灵活度高和移动性好的优势。该系统通过光生毫米波和波分复用的方式,实现了1Gb/s多媒体业务的单纤上下行传输,达到了10km光纤和5m无线的接入距离,能够满足低成本化推广应用要求。
To increase the capacity of the access network and converge services next-generation optical access network technologies are highly desirable. In this paper, we propose converged fiber-wireless radio passive optical （RPON） architecture This incorporates the low-cost and easy-control of PON and the high flexibility, good mobility of radio over fiber. With millimeter-wave optical generator and wavelength division multiplexing, our RPON system is capable of transmitting 1 Gbit/s wireless signals over 10 km single mode fiber and 5 m air distance in both the upstream and downstream. Our proposed system can be applied at low cost.
