摘 要:10G PON接入系统将成为吉比特入户的主流方案。现网已部署GPON系统平滑升级为XG PON对于减少纤芯占用,提高升级效率,简化用户数据配置具有重要的意义。本项目在中国移动集团范围内,首次在现网真实环境下,对GPON平滑升级XG PON的多个方案进行了详细评估及测试验证,并基于实测结果分析论证各方案优缺点,针对不同应用场景给出了明确的升级方案选择建议,对后续工作有显著参考价值。最后,对下一阶段的升级工作提出了建议。10G PON access system will become the mainstream for Gigabit services over FTTH program.Enabling the current GPON system’s smooth upgrade to XG PON by re-using infrastructure of dark fibre is of great significance to reduce the dark fiber occupancy,improve the efficiency of upgrading,simplify the user data configuration.In the context of China Mobile Group,for the first time in the real environment of the current network,multi solutions of the GPON smooth upgrade to XG PON were deliberately tested and evaluated.Based on the measured testing results to demonstrate the advantages and disadvantages,each solution was assigned to different application scenarios,each typical application scenario was given clear upgrade program recommendations.It is estimated that through such tests and verifications,follow-up work on the upgrades from GPON to XG PON will have reference cases.Finally,recommendations were given for the next phase of the upgrade.
