Embodiment Construction

[0039] Refer to attached Figure 1~3 , the circular covered cable structure includes an optical fiber unit 1, a strengthening member 2 and a slotted sheath 3, the optical fiber unit 1 is arranged in the middle of the circular covered cable, and both sides of the optical fiber unit 1 are provided with reinforcing members 2 parallel to each other. The outside of the unit 1 and the reinforcement 2 is covered with a slotted sheath 3 .

[0040] The slotted sheath 3 is made of materials such as polyvinyl chloride or low-smoke halogen-free flame-retardant polyolefin. The optical fiber unit 1 is a colored optical fiber unit or a tight-packed optical fiber unit, and the strengthening member is a metal strengthening member or a non-metallic strengthening member (core).

[0041] At least one optical fiber unit or tight-packed optical fiber unit is used. The optical fiber unit adopts G657A2 colored optical fiber, which is usually blue, with two cores in blue and orange, and four cores i...

Abstract

A circular rubber-covered-wire optical cable and a manufacturing method thereof of the invention relate to a compact tensile antiflaming rubber-covered-wire optical cable used for indoor wiring and the manufacturing method thereof. In the cable, metal or non-metallic strengthening pieces are used to perform parallel reinforcement. Colored optical fibers and tightly packaged fibers, which have unequal quantities, are in the middle of the parallel strengthening pieces. Slotting circle sheaths cover the fibers and the strengthening pieces. Butterfly-type rubber-covered-wire optical cable is suitable for vertical, horizontal wiring or pipeline wiring in a FTTH building. Bending performance is excellent and tensile capacity is good. Construction operation is easy to be performed. A fiber unit,the strengthening pieces and the slotting sheath are comprised. The fiber unit is arranged in the middle part of the circular rubber-covered-wire optical cable. The strengthening pieces are parallelly arranged on two sides of the fiber unit. The slotting sheaths cover the fiber unit and the strengthening pieces.

Description

technical field [0001] The invention relates to a round leather cable and its production method, which relates to a compact tensile and flame-retardant leather cable for indoor wiring and its production method. The cable adopts metal or non-metal reinforcements as parallel reinforcements, and the middle of the parallel reinforcements is For variable quantities of colored or tight-packed fibers, the fibers and strength members are covered with a slotted circular jacket. The butterfly-shaped leather cable with this structure is suitable for vertical and horizontal wiring or pipeline wiring in FTTH (fiber-to-the-home) buildings. It has excellent bending performance and good tensile strength, and is very easy to construct and operate. Background technique [0002] At present, ordinary butterfly cable technology is relatively mature and has been put into practical application. Its structure mainly adopts: colored optical fiber plus parallel reinforced flat structure, tight-packed...
