In the prior art, when the optical cable is prepared, the optical fiber passes through the oil filling mold, the fiber paste is coated, and then enters the mold core of the machine head of the extruder, the sleeve is formed on the outer periphery of the optical fiber by the molten material in the machine head, and the optical fiber and the sleeve enter the shrinkage and cooling process through the die of the extruder, and the sleeve is coated on the outer periphery of the optical fiber and the fiber paste after shrinkage.

[0003] In order to avoid the position deviation of the optical fiber from the center of the sleeve, the thickness of the fiber paste is thinned, the isolation and protection of the optical fiber are weakened, or the optical fiber is attached to the inner wall of the sleeve during the shrinkage of the sleeve, which causes the optical fiber attenuation to be too large or the fiber to be broken, the outer diameter of the sleeve to fluctuate, etc. When preparing the optical cable, the position of the oil filling mold needs to be adjusted to correct the center of the optical fiber, so that it is concentric with the mold core of the machine head, so as to ensure that the optical fiber is in the center position of the sleeve.
