A precise frequency dissemination system using optical fiber is studied. The purpose of the system is to transmit frequency standard with little deterioration to distant many users. It is composed of a phase compensation transmitter, bidirectional optical amplifiers, optical amplified distributor, and receiver. The system target is to achieve a stable transmission of hydrogen maser class signals. For short term stability, it is shown the required optical received power to realize the Allan deviation of 1×10^-13 (averaging time of 1 s). For long term stability, a new compensation method using third wavelength transmission is effective to suppress phase fluctuation induced by fiber temperature change. Experimental result shows stability of 8×10^-17 at 10⁵ s in a fiber link of 160 km in total with one bidirectional optical amplifier.
