The utility model provides a compact optical fiber amplifier with a novel heat preservation device, which comprises a shell, a regulation and control assembly and a temperature control assembly, the shell is in a sealed state, the regulation and control assembly is arranged at the upper end of the shell, the temperature control assembly comprises a vacuum pump, an electromagnetic valve and a temperature sensor, an exhaust hole is formed in the right upper side of the shell, and the vacuum pump is arranged on the inner side of the exhaust hole. According to the device, the structure is reasonable, air circulation inside and outside the device can be reduced through the shell in the sealed state, so that loss of temperature in the device is reduced, air in the device can be exhausted through the vacuum pump, the air pressure value in the device is reduced, and the device is convenient to use. Through the arrangement of the vacuum valve, the vacuum state is close, the influence of the environment on the equipmen
