Problems solved by technology

The flat structure separates optical fibers and has excellent compression resistance. The limitation of bending performance in certain directions determines that it is mainly used for single indoor wiring. When it is used both outdoors and indoors, it cannot pass through horizontal pipes in batches and is bundled vertically. Cable ties are required to tighten, and the protection of optical cables is not good

Abstract

The invention relates to an indoor and outdoor wiring cable and a production method thereof. An armored pipeline butterfly optical cable is a multicore butterfly combined optical cable which is compact in structure, extension and compression resistant, flame retardant and tightly wrapped. The armored pipeline butterfly optical cable comprises a circular butterfly optical cable unit, parallel metallic or non-metallic reinforcing parts, a water blocking tape layer and a steel tape armored longitudinal wrapping layer; non-metallic extension resistant elements are arranged above and under the circular butterfly optical cable unit; the water blocking tape layer longitudinally wraps the circular butterfly optical cable unit; the steel tape armored longitudinal wrapping layer is arranged outside a water blocking material layer in an armored mode; an outer sheath is arranged outside the steel tape armored longitudinal wrapping layer through a plastic extruding machine in a plastic wrapping mode. The armored pipeline butterfly optical cable which is suitable for vertical or horizontal wiring in FTTH (Fiber To The Home) buildings is an indoor and outdoor dual-purpose wiring optical cable which is strong in extension resistant strength and side compression resistant capability.

Description

technical field [0001] The present invention relates to an armored pipe butterfly cable and a manufacturing method thereof, which relates to an indoor and outdoor wiring optical cable and a manufacturing method thereof, and is a compact, tensile, compressive, and flame-retardant tight-packed multi-core butterfly combination fiber optic cable. Its production method: the cable adopts the center of the circular leather cable, and the external structure has the requirements of water resistance, tensile strength and lateral pressure resistance, and there are different reinforcements, and the surrounding butterfly optical cable is longitudinally wrapped, and then used in the outer layer Steel tape armor for protection and finally extruded sheaths of different sizes. This kind of structural armored optical cable is suitable for vertical or horizontal wiring in FTTH (fiber-to-the-home) buildings. It is a kind of wiring optical cable with strong tensile strength and lateral pressure r...
