By introducing an additional carrier light into the transmission link, the system effectively eliminates the effect of dispersion on temperature in the fiber link. The experimental results show that the long-term stability of microwave frequency transfer over a 100 km optical fiber link is better than 10^(-18)/d. This remarkable result strongly demonstrates the feasibility of our proposed scheme, while also highlighting its significant practical significance in ensuring the long-term stability of microwave frequency transfer across hundreds of kilometers of optical fibers.展开更多
