中文摘要： 为了顺应未来光和无线接入网的发展趋势，解决因用户接入数据的”潮汐效应”而带来的资源利用率低问题，本项目提出一种基于波长堆叠无源光网络的光和无线前传融合的接入网系统。系统通过设计波长灵活调度的结构模块，使波长资源在光和无线接入子系统之间及两个子系统内部进行优化配置；通过建立接入用户资源模型，将波长虚拟化实现资源共享，从而降低接入网系统功耗和成本；提出基于电域编码和光子微波滤波的方案，来抑制多波长共传而带来的拉曼散射问题。本项目将在已开展的无源光网络相关技术的研究基础上，探索和验证光与无线前传融合接入网的关键技术，发展一种传输速率高、接入用户多、成本低的全业务接入的下一代接入网的解决方案，推动下一代新型接入网技术的研发和应用。

英文摘要： With the development of hybrid optical and wireless access networks, some significant problems are coming out. For example, the power consumption issue, the crosstalk problem and the low resource utilization caused by the “tidal effect” of user data traffic, etc. In this project, we propose an access network with the integration of wireless fronthaul and optical access system based on wavelength stacked PON networks. In order to solve the problems mentioned above 1) we develop the wavelength scheduling module for optimally allocating the wavelength resources between the wireless access network and fixed access network, and within these two systems. 2) Besides, by modeling the user resources and the virtualization of wavelengths, the resources will be shared, thereby reducing the power consumption and cost of the system. 3) To mitigate the Raman crosstalk between the multiple wavelengths transmission system, we propose two solutions based on data coding and photonic microwave high-pass filtering respectively. Based on our ongoing related research on optical access networks, we are researching the key technologies of the integrated network between the wireless front haul and optical access networks, and to develop a full-service next generation PON system with the properties of high transmission data rate, low cost and multiple users, and make our efforts to promote the generation access networks technology and application.
