Embodiment Construction

[0018] Embodiment 1 of the dual-core optical cable of the present invention, such as Figure 5 Shown: the twin-core optical cable includes a sheath 1, an optical fiber 2 and a reinforcement 3. The optical fiber 2 and the reinforcement 3 are arranged inside the sheath 1 . There are two optical fibers 2, and the two optical fibers 2 are arranged in parallel and spaced left and right. There is a gap between the two optical fibers 2, that is, the outer circumference of each optical fiber 2 is completely wrapped by the sheath 1.

[0019] In this embodiment, a tear line 4 is provided on the sheath 1 , and the tear line 4 is located between two optical fibers 2 . There are two reinforcements 3 , and the reinforcements 3 correspond to the optical fibers 2 one by one, and each reinforcement 3 is located outside the corresponding optical fiber 2 . In this embodiment, two reinforcements 3 are arranged in parallel and spaced left and right, two optical fibers 2 are located between the t...

Abstract

The invention relates to a double-core optical cable. The double-core optical cable comprises a sheath, two optical fibers are arranged in the sheath, and a gap is formed between the two optical fibers. Due to the fact that the gap is formed between the two optical fibers, both the optical fibers are respectively coated by the sheath, after the two optical fibers are separated, both the optical fibers are still coated by the sheath and not exposed outside, and both the optical fibers can be effectively protected. The problem that after an existing double-core optical cable is torn open, optical fibers can not be effectively protected is solved.

Description

technical field [0001] The invention relates to a double-core optical cable. Background technique [0002] With the continuous progress of fiber-to-the-home (FTTH) technology and the continuous growth of bandwidth requirements, how to introduce optical fiber from the optical distribution point of the access network to the user end has become a technical hotspot that people pay attention to. Usually we refer to this section of fiber optic cable as the home fiber optic cable. [0003] At present, the home line optical cable includes single-core home optical cable and double-core home optical cable. Such as figure 1 A single-core drop cable shown includes an optical fiber 11, a strengthening element 12, a self-supporting strengthening element 13 and a sheath 14, and both the strengthening element 12 and the self-supporting strengthening element 13 are reinforcements, both of which are used to improve the strength of the optical fiber. Mechanical and tensile properties. Such...
