GS5710 Time Frequency Fiber Optic Transmission Restoration Equipment
Products Introduction
The GS5710 Time and Frequency Fiber Optic Transmission and Recovery Equipment is a comprehensive time management device that uses fiber optic or E1 link signals to transmit and recover time and frequency signals, as well as provide terminal time synchronization. It can also trace back to a higher time source via fiber optic or E1 link to recover high-precision 10MHz time signals. It is a time and frequency device with traceability and time synchronization functions.
The equipment uses a 2U standard chassis, which can be easily installed in a rack.
Application areas
Time and frequency synchronization between central station and branch stations.
Time synchronization laboratory, construction of military and civilian time and frequency systems.
Power system.
Features
