A kind of sheath embedded undercut optical cable and production method

Abstract

The invention discloses a sheath-embedded fiber optic cable and a production method thereof, comprising a sheath, a rigid reinforcement, a flexible water-blocking reinforcement, a microtube unit, a colored optical fiber, a first water-blocking element and a second water-blocking element, The exterior of the first water-blocking element and the plurality of colored optical fibers is wrapped with a microtube unit, and the exterior of the plurality of microtube units and the second water-blocking element is evenly wrapped with a flexible water-blocking reinforcement to form a cable core, and the exterior of the cable core is wrapped with Sheath, a plurality of rigid reinforcements are embedded between the outer surface and the inner surface of the sheath; the invention effectively improves the tensile and compressive properties of the product, is lighter in weight, and has a smaller outer diameter, which can meet the requirements of skylight construction Requirements; use the method of mold repair, increase the thickness of the sheath on the side without rigid reinforcement, and compensate for the shrinkage of the sheath on the side without rigid reinforcement; repair the out-of-roundness by negative pressure repair after the mold is released; ensure Improve the roundness of the cable appearance.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a sheathed embedded splice optical cable and a production method thereof. Background technique [0002] With the rapid development of fiber-to-the-home, the use of optical cables in the distribution section and the home section of the optical fiber network has increased. When wiring in buildings, it is necessary to open the skylight for optical cables. However, the weight of traditional GYTA and GYTS optical cables is heavy. The size is large, and the construction is inconvenient, and the skylight construction cannot be completed; in addition, for the optical cable that contains the sheath embedded with rigid reinforcements, when the traditional tube drawing method is used for processing, when the sheath is cooled and shaped, due to the embedded rigid reinforcements, It will cause inconsistent shrinkage around the sheath and appear flat, making it difficult to round the sh...
