Abstract:
Provided is a fully dry optical cable, which successively includes, from inside to outside: a light unit (1), a first layer of sheath (2), a braid layer (3) having multiple mesh holes, and a second layer of sheath (4), wherein the braid layer (3) is a reinforcing element, the optical cable has a first region where the first layer of sheath (2) and/or the second layer of sheath (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 where the second layer of sheath (4) is embedded in the mesh holes and is connected to the first layer of sheath (2) as a whole, or, both the first layer of sheath (2) and the second layer of sheath (4) are embedded in the mesh holes and are connected as a whole. The reinforcing 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 reinforcing element does not slide relative to the sheaths, and the structure is more secure during traction in construction. A manufacturing method for an optical cable is further provided.
