The invention discloses a wrapping and pasting device of an optical fiber. The device comprises a work bench; a bending pipe is arranged on the surface of the work bench; a first electric push rod isarranged at the front side of the bending pipe; and a support plate is arranged at the front side of the first electric push rod and is arranged at the top of the work bench. A coating pipe is communicated to one side of the bending pipe; a coating device is arranged at one side of the coating pipe; and a compression pipe is communicated with the other side of the bending pipe. According to the invention, with the bending pipe and the first electric push rod, the first electric push rod pushes a cable insulation layer and a temperature measurement fiber in the bending pipe to deform during thepasting process of the cable insulation layer and the temperature measurement fiber, so that the breaking phenomenon of the fiber due to the cable bending is avoided. And with the coating device, thepasting glue is coated on the surface of the cable insulation layer uniformly and then pasting with the surface of the temperature measurement fiber is realized, so that the coating is done uniformly, the work efficiency is high, and the labor force is reduced.
