ONU型网关融合接口的设计和实现

【】网关型ONU作为网关及PON技术的融合,不仅保持了PON原有的管理方式,还支持运营商实现远端管理。PON系统具有高带宽和低成本等优势。在ONU网关上开发融合无线接口,可以在支持传统有线业务的基础上,丰富光纤系统的接口种类。既保持原有优势,又增加系统的无线资源。传统的方法是在有线接入设备上开通无线接入通道,不能实现集中控制和管理。针对现有技术的不足,提出了新的设计方法,采用基于FPGA和嵌入式处理器的方法。进一步给出了详细的实现过程。测试验证表明该设计比原有方案有优势。

Design and implementation ofthe convergency interfaces in the gateway ONU

AS the convergence of gateway and PON technology,gateway ONU not only keeps the original management way of PON,but also supports carriers to process management function remotely. PON network with high bandwidth and low cost advantages. The development of radio interfaces in the optical access network, can be based on the support of traditional cable interfaces, rich variety of optical access network system. Not only keep the original advantages, but also enhance the system"s wireless resource. The traditional method can not realize the centralized control and management,which opened a wireless access channel in wired access equipment. Aiming at the shortages of existing technology, a new design method is proposed, which adopts the method based on FPGA and embedded processor. The test shows that the design has more advantages than the original scheme.
