基于现代应急通信的OLT救援系统创新研究OA

After the interruption of home broadband optical cable,due to the complex and changeable situation of the fault site,there is often no spare available optical cable core,and the investigation and repair of optical cable breakpoints takes a long time,which makes it difficult for the business to recover quickly.Therefore,the reliability and efficiency of the emergency communication system become the key.This paper combines traditional OLT technology with modern emergency communication technology to build a new OLT emergency rescue system.The system is divided into two types,wired and wireless.The wireless emergency rescue part not only integrates various network element functions such as PON and 5G CPE,but also establishes a two-layer channel with BRAS through the 5G wireless interface to achieve high-speed and stable uplink and backhaul of data,greatly reducing the impact of faults and improving user perception.
