The invention relates to the technical field of optical fiber processing, in particular to an optical fiber deuterium gas treatment system which comprises an optical fiber treatment box assembly, a gas recovery assembly, a vacuumizing assembly, a compression assembly, a deuterium gas assembly, a helium gas assembly, a heating assembly, a recovery pipeline and a main pipeline. After optical fiber processing is finished, mixed gas in the deuterium gas cabinet is conveyed into the gas recovery tank through the compressor, the amount of deuterium gas needing to be supplemented is controlled through the PID controller, deuterium gas supplementing is stopped when the concentration of the deuterium gas in the recovery tank is 1.5%-2%, and then the gas in the recovery tank is conveyed into the deuterium gas cabinet again for optical fiber processing. Therefore, the deuterium gas is recycled, and the utilization rate of the deuterium gas is greatly improved; the recycling of deuterium gas not only saves resources, but
