随着"IPTV下乡""千兆小区"战略的实施,宽带普遍提速,导致OLT上行普遍升级为2GE、4GE甚至10GE,而BRAS设备下沉至郊县.某省联通大规模建设县乡OTN系统用于承载乡镇OLT上行,因此根据业务需求及某省联通基础架构规划情况,提出了县乡OTN组网及板卡配置思路,用于指导县乡OTN系统精准建设,实现降本增效.

With the implementation of the strategy of“IPTV going to the countryside”and“Gigabyte community”of Unicom in a province,the speed of broadband is generally increased,resulting in the general upgrade of OLT uplink to 2GE,4GE,or even 10GE,and the subsidence of bras equipment to the countryside.A largescale construction of county and township OTN system by a provincial Unicom is used to carry the OLT uplink of the township.According to the business needs and the infrastructure planning of a provincial Unicom,this paper proposes the idea of county and township OTN networking and board configuration,which is used to guide the precise construction of a provincial Unicom OTN system and achieve the purpose of cost reduction and efficiency increase.
