Simulation of the Effect of Modulation Depth on Fiber Frequency Transfer

Frequency transmission via optical fiber is pivotal in fields such as geodesy and deep space exploration due to its precision and reliability. Among various transmission methods, RF frequency transmission stands out for its simplicity and cost-effectiveness. We've constructed a simulation platform for optical fiber frequency transmission to meticulously assess the impact of varying modulation depths on frequency stability. Our findings reveal that fractional frequency stability is enhanced as modulation depth increases, provided it stays within the linear operational range of the modulator.
