新型家庭全光网技术

New Home All-Optical Network Technology

提出了光纤到房间(FTTR)新型家庭全光网相关技术。围绕底层支撑、网络管理和业务保障3类技术,中兴通讯取得一系列技术创新和应用改进:研发FTTR无源光网络(PON)芯片,实现主从网关的点到多点(P2MP)架构功能,编制家庭光纤施工技术指导书,解决FTTR落地推广中光纤分布式网络(ODN)布线施工难的问题,打造智能管理云平台,实现FTTR网络的管理,包括网络拓扑管理和性能数据采集,提出五维评分体系和无线接入终端切换模型分析,使全屋漫游“选得好”且“切得快”,漫游切换时延低至20 ms。指出家庭网络在飞速演进,FTTR会面临更多挑战,中兴通讯将持续进行FTTR技术攻关,推动家庭网络新基建。

New home all-optical network technologies related to Fiber to The Room(FTTR)are proposed.Based on three categories of tech⁃nologies covering the bottom infrastructure,network management,and service assurance,ZTE has achieved a series of technological inno⁃vations and application improvements:The FTTR passive optical network(PON)chipsets are developed to realize the point-to-multipoint(P2MP)architecture functions of the master and slave gateways;the technical guide of home optical fiber construction is formulated to solve the difficulties in optical fiber distributed network(ODN)cabling construction in FTTR implementation;a smart management cloud plat⁃form is developed to implement manageability of the FTTR network,including network topology management and performance data collec⁃tion;the five-dimensional rating system and STA handover model analysis are proposed to realize the whole-home roaming"selected well"and"cut quickly",building the roaming handover delay as low as 20 ms.It is pointed out that the home network is evolving rapidly,and FTTR will face more challenges.ZTE Corporation will continue to tackle the key problems of FTTR technology and promote the new infrastructure of home network.
