同步以太网在5G网络设备中的应用

随着高速率、低延时和大连接5G(5^(th) Generation)网络的发展和移动宽带化的逐渐普及,一种新型小型基站5G基站应运而生。同时5G传输网络及业务已向分组化网络方向发展,对频率同步和时间同步提出新的要求。文章描述同步以太网SYNC-E (Synchronization Ethernet)在5G CU、5G DU和5G RU设备中的应用及其实现,详细地介绍同步以太网SYNC-E电路设计、以太网SYNC-E PHY接口设计、同步以太网SYNC-E程序设计以及如何验证测试同步以太网SYNC-E,并最终在5G设备中通过使用同步以太网达到全部5G网络设备频率同步,从而为实现数据通信的实时性、可靠性提供强有力的保证。

With the development of high-speed,low-latency and large-connection 5G(5^(th) Generation) networks and the gradual popularization of mobile broadband,a new type of small base station 5G base station has emerged.At the same time,the 5G transmission network and services have developed in the direction of packetized network,which puts forward new requirements for frequency synchronization and time synchronization.This paper describes the application and implementation of SYNC-E(Synchronization Ethernet) in 5G CU,5G DU and 5G RU equipment,and describes in detail the circuit design of SYNC-E,Ethernet SYNC-E PHY interface design,synchronous Ethernet SYNC-E program design and how to verify and test synchronous Ethernet SYNC-E,and finally achieve frequency synchronization of all 5G network equipment by using synchronous Ethernet in 5G equipment,so as to realize real-time data communication Provides a strong guarantee for performance and reliability.
