We demonstrate bright quantum frequency comb generation in a periodically poled lithium niobate Fabry-Perot microresonator. Photon-pair correlations are characterized across 231 frequency-bin pairs over a 70 nm telecom band, achieving 6×10⁸ pairs.s^-1.mW^-1.GHz^-1 spectral brightness and CAR ~10⁴ at 0.5 μW.
