Abstract
The invention discloses an optical cable manufacturing method. The method comprises the following steps that: 1) a cable core is positioned by a positioning mechanism after entering a pasting container, and then the cable core penetrates out from an outlet of the pasting container; and 2) an ointment scraping hole elastic in size is utilized to scrape redundant ointment on the cable core penetrating out from the pasting container. According to the invention, the positioning mechanism is capable of improving the coaxiality between the cable core and the outlet of the pasting container, so that the uniformity of the ointment on the periphery of the cable core is well improved; in addition, the ointment scraping hole elastic in size is arranged, so that the cable core is prevented from being pressed excessively by the ointment scraping hole, and the quality of an optical fiber in the cable core is effectively ensured.
Description
Technical field
The present invention relates to fiber optic cable manufacture technique, be specifically related to fiber optic cable manufacture method.
Background technology
One of permeability performance key factor being to ensure that cable lifetime of optical cable, the index that it is optical cable manufacturer and operator pays close attention to very much. Because optical cable is once infiltration, under environment complicated and changeable, optical fiber to optical cable infiltration and migration, can be caused reversible or irreversible hydrogen loss, affect the stability of fiber lifetime and long-term delivery by moisture and moisture outside optical cable.
Along with fiber optic cable manufacture technology and material development, in order to improve the block-water performance of optical cable, generally cable core is filled greasy for preventing water and block water. The ultimate principle of factice for filling is: utilize oil pump to be transported in container by ointment, and cable core, through one end, in container after factice for filling, passes from the other end of container, and strikes off unnecessary ointment by scraping oilhole. The effect scraping oilhole is to control ointment amount, because the impact of gravity, through scraping oilhole, the position of cable core is generally on the lower side, and this can cause that cable core lower part ointment amount is few, and upper part ointment amount is many so that cable core week affects late stage process along each several part ointment lack of homogeneity. And existing oilhole of scraping all adopts metal die to prepare, hole size is fixed, and has slightly bigger than normal once run into cable core diameter or pricks the loose situation of yarn, the optical fiber in cable core sleeve pipe can be caused extruding, affect the transmission performance of optical fiber.
