Fiber Optic Time Transfer

The T900-P is a high-precision fiber-optic time transfer device based on wavelength division multiplexing links. It utilizes a central station and terminal station architecture and incorporates bidirectional time comparison technology to achieve stable, interference-resistant time and frequency synchronization within DWDM channels. The system supports a transmission distance of 100 kilometers and offers synchronization accuracy better than 40ps. It is widely used in high-precision synchronization scenarios such as deep space exploration, national defense, and scientific research.
