Sheath embedded connection optical cable and production method thereof

Abstract

The present invention discloses a sheath embedded connection optical cable and a production method thereof. The sheath embedded connection optical cable comprises a sheath, rigid reinforcers, flexiblewater blocking reinforcers, mini-tube units, coloring optical fibers, a first water blocking element and a second water blocking element, the first water blocking element and the coloring optical fibers are coated with the mini-tube units, the mini-tube units and the second water blocking element are uniformly coated with the flexible water blocking reinforcers to form a cable core, the cable core is coated with the sheath, and the rigid reinforcers are inlaid between the outer surface and the inner surface of the sheath. The sheath embedded connection optical cable and the production methodthereof effectively improve the tensile property and the compressive property of products, the weight is lighter, the outer diameter is smaller, and the requirement of skylight opening construction can be met; the mould repairing method is employed to increase the thickness of the sheath at one side without the rigid reinforcers and compensate the shrinkage of the sheath at the side without the rigid reinforcers; and after the mould is generated, a negative pressure repairing mode is employed to repair unrounded degree so as to ensure the rounding of the appearance of the optical fiber.

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...
