The invention provides an optical fiber single-channel time frequency high-precision transmission intermediate node device. An intermediate node is arranged in an optical fiber single channel for communication between a local end and a far-earth end and is used for coupling and detecting a second pulse signal and a frequency signal which are sent to the far-earth end by the local end of the singlechannel and a second pulse signal and a frequency signal which are sent to the local end by the far-earth end. The intermediate node device can accurately recover the time frequency signal of the intermediate node connected with the local end and the remote end single channel. 本发明提供一种光纤单信道时间频率高精度传递中间节点装置，设置在本地端和远地端通信的光纤单信道的中间节点，耦合探测出单信道的本地端发送至远地端的秒脉冲信号和频率信号，及远地端发送至本地端的秒脉冲信号和频率信号。上述中间节点装置能够准确恢复出连接本地端和远地端单信道的中间节点的时间频率信号。
