Embodiment 1

[0021] The invention discloses a butterfly optical cable (see attached figure 1 , 2 ), including: a pair of reinforcing pieces 1 and a main piece 2, the pair of reinforcing pieces 1 are respectively arranged on both sides of the main piece 2; The edge 3 is connected with the main part 2 through the adhesive layer 4, the sharp edge 3 protrudes to the inside of the main part 2, the sharp edge 3 is connected to the extension part 5, and the extension part 5 covers the outer surface of the reinforcement part 1 ; The sharp edge 3 and the extension 5 are made of pressure-resistant materials; the main part 2 is provided with a foam layer 6, and the foam layer 6 is made of a foam material, and the foam material is filled with nitrogen, nitrogen The pressure is greater than or equal to 1.5 standard atmospheric pressure, the optical fiber 7 is arranged in the foam layer 6 ; the radial height of the main part 2 is less than or equal to the radial height of the reinforcement part 1 . In...

Embodiment 2

[0025] The sharp edge 3 is a rod-shaped structure on the protruding section, and the tip of the sharp edge 3 has a beak (see attached image 3 ), the pointed edge 3 is connected to the main part 2 through the adhesive layer 4 . The adhesive layer 4 is other materials with low density and low adhesive strength.

[0026] When implementing the embodiment of the present invention, hold the two ends of the reinforcing piece, apply force to the left and right respectively, separate the reinforcing piece and the main piece, obtain deep openings on both sides of the main piece, peel off the insulating material on the main piece from the opening, and finally simply peel off the hair. Bubble material to get bare fiber.

Abstract

The invention discloses a butterfly optical cable, comprising: a pair of reinforcements and a main part, the pair of reinforcements are respectively arranged on both sides of the main part; the side of the reinforcement near the main part is provided with a sharp edge, and the sharp edge passes through the adhesive layer Connected with the main part, the sharp edge protrudes toward the inner side of the main part, the sharp edge connects the extension part, and the extension part covers the outer surface of the reinforcement part; the sharp edge and the extension part are made of pressure-resistant materials; the main part is provided with a foam layer, The foam layer is made of foam material filled with nitrogen, the nitrogen pressure is greater than or equal to 1.5 standard atmospheric pressure, and the optical fiber is arranged in the foam layer; the radial height of the main part is less than or equal to the radial height of the reinforcing part. In the present invention, by providing a reinforcement with a sharp edge and an extension part, the pressure resistance of the reinforcement is better, and at the same time, the sharp edge is connected to the main part through an adhesive layer, so that the sharp edge is more easily separated from the main part, and the main part after separation Two opposite grooves are formed, and the optical fiber can be obtained by further tearing the foam layer. The invention is easy to operate and has excellent protection performance.

Description

technical field [0001] The invention relates to the field of optical fiber and cable production, in particular to a butterfly cable. Background technique [0002] Butterfly optical cable is a new type of user access optical cable. According to different application environments and laying conditions, the optical cable structure and various technical parameters are reasonably designed, and it combines the characteristics of indoor flexible optical cable and self-supporting optical cable. Butterfly optical cable is the best candidate product for FTTX network solutions, and plays a unique role in the establishment of intelligent buildings, digital communities, campus networks, local area networks and other networks. [0003] Existing butterfly optical cables: 1) adopt rounded square, runway, and 8-shaped designs, often twisted during the wiring process, and because the butterfly optical cable is a tight structure, stress is generated on the optical fiber, resulting in attenuati...
