Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical cable technology, specifically a self-supporting bird-pecking-proof optical cable. Background Technology
[0002] Self-supporting aerial optical cables are frequently damaged by bird strikes, resulting in sheath damage and fiber breakage, causing communication interruptions. Traditional optical cable sheaths lack sufficient rigidity and specific protective measures.
[0003] In existing technologies, some solutions only involve adding irritating chemicals to repel birds, but these solutions suffer from poor environmental friendliness and short effective periods. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a self-supporting bird-pecking-proof optical cable, solving the aforementioned technical problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-supporting bird-pecking-proof optical cable, comprising a suspension wire protective sleeve, a suspension wire arranged within the suspension wire protective sleeve, an optical cable protective sleeve, and a neck for connecting the suspension wire protective sleeve and the optical cable protective sleeve. The optical cable protective layer is provided with a bird-pecking-proof armor layer, and an inner protective layer is arranged on the lower surface of the bird-pecking-proof armor layer. The lower surface of the inner protective layer is provided with multiple loose tubes and a central reinforcing rib. Multiple optical fibers are arranged inside the loose tubes. The bird-pecking-proof armor layer is composed of multiple rigid round rods and rigid triangular tips distributed at intervals along the circumference.
[0008] Preferably, the plurality of loose tubes are evenly arranged around the central reinforcing rib in the circumferential direction, and the space between the plurality of loose tubes and the central reinforcing rib is filled with cable filling grease.
[0009] Preferably, the space between the optical fiber and the loose tube is filled with fiber filler grease.
[0010] Preferably, the loose sleeve is made of PBT material, has a diameter of 1.8 mm, and a wall thickness greater than 0.3 mm.
[0011] Preferably, the central reinforcing rib is a phosphated steel wire with a diameter greater than 2 mm.
[0012] Preferably, the inner protective layer consists of an inner sheath of the optical cable and a corrugated steel strip, wherein the thickness of the corrugated steel strip is greater than 0.2 mm, and the inner sheath of the optical cable is a polyethylene sheath with a thickness greater than 1 mm.
[0013] Preferably, both the suspension cable protective sleeve and the optical cable protective sleeve are made of AT-resistant tracking polyethylene.
[0014] Preferably, the suspension wire is composed of 7 strands of 1mm galvanized steel wire twisted together.
[0015] Compared with the prior art, this utility model provides a self-supporting bird-pecking anti-optical cable with the following beneficial effects: the utility model, by setting a rigid triangular tip and a rigid round rod, allows the rigid triangular tip to be exposed after the bird bites through the outer sheath, and the rigid triangular tip can pierce the bird's mouth. At the same time, the rigid round rod fills the gap between two adjacent rigid triangular tips, thereby preventing birds from avoiding the rigid triangular tips and continuing to damage the optical cable, further improving the bird-pecking effect of the optical cable.
