Embodiment 1

[0048] A bulletproof butterfly cable, comprising a plastic sheath, the plastic sheath includes an upper cylindrical portion and a lower square cylindrical portion, a reinforcing member is arranged inside the cylindrical portion, and the cylindrical portion is coated on On the reinforcement, the square tube part is provided with several optical fibers, and the optical fiber is coated with a water-blocking tape in a ring shape. The square tube part is covered on the water-blocking tape. U-shaped bulletproof steel belt, the opening direction of the U-shaped bulletproof steel belt is towards the reinforcement side, the water blocking belt is located in the opening of the U-shaped bulletproof steel belt, and the square tube is covered by the U-shaped bulletproof steel belt superior.

[0049] Through this setting, the optical cable adopts a butterfly structure, the upper part is a reinforcement and a plastic sheath covering it, the lower part is one or more optical fibers coated wit...

Embodiment 2

[0051] On the basis of Example 1, the reinforcement is made of steel wire or non-metal.

Embodiment 3

[0053] On the basis of the above embodiments, the distance between the junction of the cylindrical portion and the square cylindrical portion and the water blocking strip is 0.1-0.2mm. Through this setting, it can be ensured that the water blocking tape can be exposed when the plastic sheath is torn off, which is convenient for the staff to install and maintain.

Abstract

The invention discloses a bulletproof butterfly-shaped cable, belongs to the technical field of optical communication, and aims to provide a bulletproof butterfly-shaped cable to solve the problems that an existing bulletproof leading-in optical cable is high in manufacturing cost, and a steel belt is not easy to strip. The optical cable comprises a plastic sheath, the plastic sheath comprises a cylinder portion on the upper side and a square cylinder portion on the lower side, a reinforcing piece is arranged in the cylinder portion, the cylinder portion wraps the reinforcing piece, the square cylinder portion is provided with a plurality of optical fibers, the optical fibers are annularly wrapped by a water-blocking tape, the square cylinder portion wraps the water-blocking tape, a U-shaped bulletproof steel belt is further arranged on the outer side of the water-blocking tape in the square cylinder part, the opening direction of the U-shaped bulletproof steel belt faces one side of the reinforcing piece, the water-blocking tape is located in the opening of the U-shaped bulletproof steel belt, and the square cylinder part wraps the U-shaped bulletproof steel belt. The bulletproof butterfly-shaped cable is suitable for the bulletproof butterfly-shaped leading-in optical cable.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a bulletproof butterfly cable. Background technique [0002] Butterfly optical cable is a kind of user access optical cable. According to different application environments and laying conditions, the optical cable structure and various technical parameters are reasonably designed. It combines the characteristics of indoor soft optical cable and self-supporting optical cable. It is the best product for FTTX network solutions. It plays a unique role in the establishment of intelligent buildings, digital communities, campus networks, local area networks and other networks. Self-supporting butterfly access cables are generally used for self-supporting overhead installations, and sometimes encounter damage from shotguns. [0003] Existing butterfly-shaped drop cables include indoor and outdoor types, such as figure 2 As shown, two steel wires (or non-metall...
