  • Publication number: 20240080100
    Abstract: A broadband radio frequency signal optical fiber phase-stable transmission system includes a local end and a remote end connected by a dispersion compensation module and an optical fiber. The local end modulates a first auxiliary signal whose frequency is half of the frequency of the to-be-transmitted signal and a second auxiliary signal whose frequency is 1.5 times the frequency of the to-be-transmitted signal through the optical carrier and filters out a lower sideband to obtain an optical signal containing only the optical carrier, a first signal, and a second signal corresponds to the optical signal of the first-order upper sideband. The optical signal is transmitted to the remote end through the dispersion compensation module and the optical fiber.
