The T900-F fiber-optic high-precision frequency transmission equipment is a multi-point high-precision frequency transmission system based on a ring network. The system consists of a central station and terminal stations. The central station primarily comprises an optoelectronic unit, a high-precision measurement and compensation unit, a time-frequency interface unit, and a circulator optical filter processing unit. The terminal station also primarily comprises an optoelectronic unit, a high-precision measurement and compensation unit, a time-frequency interface unit, and an optical filter processing unit. The central station of this system only needs to transmit the frequency signal in a closed loop and compensate for phase fluctuations across the entire link, eliminating the need for phase stabilization design for individual nodes. Whether adding or removing users within the network, only optical power needs to be adjusted, significantly improving system scalability and reducing maintenance. The reproduced frequency signal has a relative frequency stability of 3\u00d710-14@1s and 1\u00d710-16@10,000s.<\/p>\n
It can be applied in basic science, deep space exploration, modern high-tech equipment and other fields.<\/p>","protected":false},"excerpt":{"rendered":"
The T900-F is a high-precision fiber-optic frequency transmission device based on a ring network structure. A central station transmits frequency signals through a closed loop and uniformly compensates for phase fluctuations, eliminating the need for individual phase stabilization at each node.
