Embodiment Construction

[0012] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0013] Such as figure 1 As shown, a miniature all-dielectric self-supporting optical fiber cable includes a sheath 6, an optical fiber cable core 2 and a strength member 4 are arranged in the sheath, and a loose tube 5 is provided on the outer jacket of the optical fiber cable core. In the casing 5, two reinforcements 4 are provided, which are respectively located on both sides of the loose casing and twisted with the loose casing. 12 groups of fiber optic cable cores are arranged in the loose tube 5, and a fiber paste 1 is arranged between the fiber optic cable core and the loose tube. A water blocking yarn 3 is arranged at the intermediate position formed by the reinforcing member and the loose tube. A water-blocking aramid yarn 7 is arranged between the reinforcement, the loose tube and the sheath. The reinforcement is an FRP reinforcement, and t...

Abstract

The invention relates to a micro full-medium self-supporting optical cable, which comprises a sheath, and optical fiber cable cores and reinforcing parts are arranged in the sheath. A loose tube sleeves outside the optical fiber cable cores which are all gathered in the loose tube, and two reinforcing pieces are arranged on the two sides of the loose tube respectively and are twisted together withthe loose tube. According to the invention, the overall structure is improved, the tension value is increased, the outer diameter is also reduced, and the overall performance of the optical cable isimproved.

Description

Technical field [0001] The invention relates to a self-supporting optical cable. Background technique [0002] The traditional self-supporting optical cable has a 1+6 structure, that is, only one FRP strength member is provided, and it is set in the middle of the 6 groups of optical fiber cable cores, which can no longer meet the current needs in terms of structural strength and volume. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the present invention provides a miniature all-dielectric self-supporting optical cable with a small volume and a strong structure. [0004] A miniature all-dielectric self-supporting optical cable, comprising a sheath, an optical fiber cable core and a reinforcing member are arranged in the sheath, and a loose tube is arranged on the outer jacket of the optical fiber cable core. The characteristic is that the optical fiber cable cores are gathered in a loose tube. In the casing, there are two r...
