Embodiment 1

[0027] refer to figure 1 As shown, an embodiment of the lightweight anti-bird pecking optical cable of the present invention includes a central bundle tube 3, and the central bundle tube 3 is a loose sleeve formed by extruding polybutylene terephthalate or modified polypropylene tube, the diameter of the loose tube is 1.8-2.6mm, the wall thickness of the loose tube is 0.2mm-0.3mm, and a plurality of optical fibers 1 are arranged in the central bundle tube 3, and the optical fibers 1 can be Bulk optical fiber, ribbon optical fiber or bundled optical fiber, the optical fiber 1 includes a bare optical fiber and a colored layer, the number of the optical fiber 1 is 4 to 12, and the central bundle tube 3 is filled with Fiber ointment 2. The outside of the central bundle tube 3 is covered with a reinforcement layer, an inner sheath 5 and an outer sheath 7 in sequence; the reinforcement layer is a water-blocking glass fiber yarn 4, and the water-blocking glass fiber yarn 4 is relati...

Embodiment 2

[0034] The anti-bird pecking optical cable in embodiment 2 is the same as in embodiment 1, and the outer sheath 7 includes the following parts by weight: 55 parts of polyamide fiber; 20 parts of high-density polyethylene; 15 parts of red color masterbatch 6 parts of carbon black masterbatch; 6 parts of capsicum; 5 parts of antioxidant; 2 parts of compatibilizer; 10 parts of flame retardant;

[0035] In this embodiment, a flame retardant is added to make the optical cable have a flame retardant effect while preventing birds.

Abstract

The invention discloses a light anti-bird-pecking optical cable and a making method thereof. The optical cable comprises a center beam tube, multiple optical fibers are arranged in the center beam tube, and a reinforcement layer, an inner protection layer and an outer protection layer wrap the exterior of the center beam tube in sequence; the reinforcement layer is waterproof glass fiber yarn, multiple pieces of waterproof glass fiber yarn seamlessly wind the outer side of the center beam tube through twisting, and two parallel non-metal reinforcement parts are embedded in the inner protectionlayer and are parallel to the center beam tube; the outer protection layer is a red sheath, and multiple glass fiber particles are embedded in the outer protection layer. According to the light anti-bird-pecking cable, a non-metal reinforcement layer is adopted for replacing a metal armor layer in the prior art, and by adopting the red sheath and the glass fiber particles embedded in the sheath,the effective anti-bird effect is achieved.

Description

technical field [0001] The invention relates to the field of optical cable manufacturing, in particular to a light bird-peck-proof optical cable and a preparation method thereof. Background technique [0002] With the rapid development of the optical fiber and cable industry, the overhead laying of optical communication networks has become more compact. Some aerial optical cables pass through woods or mountainous forest areas. Birds often stay on the surface of the optical cable, often pecking the outer sheath, or even pecking off the optical fiber. , causing communication failure. [0003] In order to prevent birds from pecking at the optical cable, one of the main structures of the traditional overhead optical cable is the armored anti-bird optical cable. Good anti-bird effect, but the armored cable increases the outer diameter, weight, and cost of the optical cable after adding armor, and the entire optical cable is relatively bulky. All links such as the production of ...
