Abstract

The invention provides a novel central beam tube-type air blowing micro anti-ant optical cable, which comprises a loose tube and a plurality of optical fibers coated inside, wherein a water blocking material fills the gap between the optical fibers; the loose tube is sequentially coated with an inner protection layer and an outer protection layer; a function assembly is arranged between the innerprotection layer and the loose tube; and the optical fibers are uniformly separated by the water blocking material and are not disturbed by each other, and signal transmission is stable and reliable.The structure is stable and reliable, the inner protection layer and the outer protection layer are arranged outside the loose tube at the same time, the two are matched for together playing a role oftorsion resistance and impact resistance, and a protection role is effectively played towards the inner optical fibers. The novel central beam tube-type air blowing micro anti-ant optical cable has the advantages that the anti-mouse bite ability is strong, the friction-resisting performance and the pressure-resisting performance are good, and the air blowing performance is excellent.

Description

technical field

[0001] The invention belongs to the technical field of optical cable production and manufacturing, and in particular relates to a novel central bundle tube type air-blown miniature ant-proof optical cable. Background technique

[0002] With the development of the optical communication industry, the pipeline resources of the metropolitan area network are becoming more and more tense, so the application of air-blown micro-optical cables is born. The use of small-diameter loose tubes and single-layer PE sheaths can effectively increase the laying density of pipeline optical fibers. , but due to the thin wall thickness of the PE sheath, its anti-ant performance is weak in the pipeline environment; secondly, its friction resistance and pressure resistance are weak, which will inevitably affect its air blowing performance. Contents of the invention

[0003] In view of this, the present invention aims to overcome the above-mentioned defects in the prior art, and p...
