Embodiment 1

[0026] Such as figure 1 As shown, the present invention includes a central strength member 3 and a cable core composed of three optical fiber bundles 5 twisted around the central strength member 3, and the outer circumferential surface of the cable core is coated with a water blocking tape 4 and an auxiliary strength member in turn. 2 and sheath 1. The cross-section of the optical fiber bundle 5 is circular, and is formed by fixing three optical fibers 51 in bundles at intervals inside the ultraviolet curable resin 52. The central reinforcing member 3 is steel wire or FRP and is wrapped with a water-blocking yarn 31 for water-blocking. Belt 4 is single-sided water-blocking tape, double-sided water-blocking tape, laminated single-sided water-blocking tape or laminated double-sided water-blocking tape, and the auxiliary reinforcement 2 is one of glass fiber and aramid fiber, or the above-mentioned A mixture of two fibers, the sheath 1 is polyethylene, polyvinyl chloride, polyur...

Embodiment 2

[0028] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the number of optical fibers 51 in the optical fiber bundle 5 is twelve.

Embodiment 3

[0030] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the number of optical fiber bundles 5 is twelve.

Abstract

The present invention relates to an optical cable for communication network, and specifically to a UV optical cable which comprises a central reinforcement, a plurality of optical fiber bundles twisted around the central reinforcement, and the sleeves coated on the peripheral surface of the plurality of optical fiber bundles. Each optical fiber bundle is formed by a plurality of optical fibers which are alternately fixed in the UV curing resin with a beam shape. The invention uses the UV optical fiber bundle as an optical fiber unit. The clearance between the optical fibers in the UV optical fiber bundle is filled by UV cured resin. The diameter of optical cable is greatly reduced. The density of optical cable is increased. The optical cable for communication network has the advantages of small diameter, light weight, high production rate, convenient and quick welding, etc. The pipe wiring of optical cable in the building greatly saves the resource of pipe and furthermore facilitates the optical fiber branching without cutting off the optical fiber. The optical cable of the invention is a novel optical cable for aiming at the FTTH communication network construction.

Description

technical field [0001] The invention relates to an optical cable for a communication network, in particular to a UV optical cable. Background technique [0002] In the implementation process of FTTH, optical cable wiring is a problem that pays more attention to in the construction of FTTH network. Optimizing the existing optical cable structure, materials, and production process can improve the production efficiency of optical cable, reduce the production cost of optical cable, improve the wiring method of optical cable, better meet the requirements of FTTH network construction, and promote the popularization of FTTH nationwide. [0003] At present, the optical fiber unit of the outdoor optical cable of the access network mainly has the following structures. [0004] One structure is a loose tube structure filled with ointment, and multiple optical fibers are randomly distributed in the loose tube filled with ointment. In this structure, when the optical cable construction ...
