The invention discloses an optical fiber filtering device which has functions of actively filtering light noises and uniformly and effectively heating internal disc winding parts. The optical fiber filtering device structurally comprises an optical fiber wire, an optical fiber box, a heating sheet, heat insulation cotton and a heat-conducting silicon gel sheet, wherein the optical fiber box is internally provided with an external disc winding part and an internal disc winding part; the external disc winding part is provided with a storage space for storing the 100m-150m optical fiber wire in a winding manner; after the optical fiber wire is wound for 100m-150m through the external disc winding part, the optical fiber wire enters the internal disc winding part; the internal disc winding part covers the heat insulation cotton; the heat-conducting silicon gel sheet is attached on an inner wall of the heat insulation cotton; the heating sheet is laid between the heat insulation cotton and the heat-conducting silicon gel sheet; after the optical fiber wire is wound in the internal disc winding part, the optical fiber wire is led out of the optical fiber box; and in a winding process, a wire disc formed by the optical fiber wire is in contact with the heat-conducting silicon gel sheet and is uniformly distributed relative to the heat-conducting silicon gel sheet. The optical fiber filtering device has the technical advantages that the heat preservation performance is good after heating, and light pulse with signal interference, caused by the fact that a laser device is started and stopped, can be effectively shielded.
