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.
