摘　　要：在FTTH建设中,面对现有主干光纤资源匮乏、机房选址难、建设成本高、网络传输交换设备部署"下沉"困难、网络规划设计复杂、难以执行先进的"模块化"设计规范等诸多问题,就野外光网络分前端及网格化光纤入户系统作了介绍,并对采用野外光网络分前端联网及典型应用作了阐述。In the construction of FTTH, confronted with the lack of existing backbone fiber resources, the difficulty in site selection of the service room, the high cost of construction, the difficulty in deploying network transmission and exchange equipment, the complexity of network planning and designing, and the difficulty in implementing the advanced Modularization specifications, this article gives an introduction of the sub-headend of the field optical network and the grid FTTH, and expounds the networking and typical application of the field optical network.
