Description

1. Technical field [0001] The invention relates to a device for implementing optical fiber communication based on satellite time base signal insertion, in particular to a device for implementing synchronization signals using Beidou and GPS time base signals to insert input and output frames. 2. Background technology [0002] GPS is the abbreviation of English Global Positioning System (Global Positioning System). GPS began as a project of the US military in 1958 and was put into use in 1964. In the 1970s, the US Army, Navy and Air Force jointly developed a new generation of satellite positioning system GPS. The main purpose is to provide real-time, all-weather and global navigation services for the three major fields of land, sea and air, and for some military purposes such as intelligence collection, nuclear explosion monitoring and emergency communication. After more than 20 years of research and experiments, it cost 30 billion US dollars. By 1994 , 24 GPS satellite cons...
