摘　　要：目前网络中多种PON模式共存,而传统的OLT软件处理多种PON模式时存在兼容能力差、开发繁琐、重复等问题。本文提出了一种兼容多模OLT的统一平台架构,支持现存多种PON模式,并具有优秀的向后兼容能力。该架构通过不同的速率组合对应SerDes通道实现了速率兼容,并对ONU进行统一管理和带宽分配,在软件上实现了多模协议栈兼容和多芯片适配。本文采用不同OLT业务板卡搭载统一平台,对注册和打流业务功能进行测试。结果表明,该平台架构兼容包括50G PON在内的6种PON模式,并支持在不同板卡上的模式切换。同时,能降低OLT产品的管理难度,缩短项目周期,降低研发成本,对50G PON和未来PON网络新技术的兼容和平滑升级具有重要意义。At present,multiple PON modes coexist in the network,while traditional OLT software has problems such as poor compatibility,cumbersome development,and duplication when dealing with multiple PON modes.This article proposes a unified platform architecture that is compatible with multimode OLT,which can support multiple existing PON modes and has excellent backward compatibility capabilities.The architecture achieves rate compatibility through different rate combinations corresponding to SerDes channels,and unifies the management and bandwidth allocation of ONUs,achieving multi-mode protocol stack compatibility and multi-chip adaptation in the software.This article uses different OLT business boards equipped with a unified platform to test registration and streaming business functions.The results indicate that the platform architecture is compatible with six PON modes,including 50G PON,and supports mode switching on different boards.At the same time,it can reduce the management difficulty of OLT products,shorten the project cycle,reduce the research and development cost,which is of great significance for the compatibility and smooth upgrading of new technologies of PON network(such as 50G PON)in the future.
