totally dry optical cable, and method for its manufacture.

摘要

A completely dry optical cable is provided, which successively includes, from the inside to the outside: a light unit (1), a first coating layer (2), a braid layer (3) with multiple mesh holes, and a second sheath layer (4), where the braid layer (3) is a reinforcement element, the optical cable has a first region in which the first sheath layer (2) and / or the second sheath layer (4 ) extend, adjacent to a surface of the braid layer (3), to the mesh holes of the braid layer (3) and are embedded in the mesh holes, and at least part of the first region is a second region in which the second coating layer (4) is embedded in the mesh holes and is connected to the first coating layer (2) as a whole, or both the first coating layer (2) and the second coating layer (4) are embedded in the mesh holes and are connected as a whole. The reinforcement element of the optical cable is embedded between the two layers of sheath, and the two layers of sheath are connected as a whole, so that the reinforcement element does not slip in relation to the sheaths, and the structure is more secure during construction. A manufacturing method for an optical cable is additionally provided.
