Description

Technical Field

[0001] The utility model relates to the technical field of communication cables, in particular to a pipeline butterfly-shaped lead-in data cable. Background Art

[0002] Fiber optic ribbon data cable is a communication cable used for high-speed data transmission. It consists of multiple optical fibers tightly arranged and packaged together to form a fiber optic ribbon, which is then combined with other components (such as reinforcement elements and sheath materials) to form a complete cable. Compared with a single optical fiber cable, fiber optic ribbon data cable has higher density and better manageability. It is very suitable for use in data centers, local area networks (LANs), metropolitan area networks (MANs) and other application scenarios that require a large number of optical fiber connections. The butterfly-shaped lead-in cable is a type of fiber optic data cable;

[0003] Butterfly drop cable, also known as "skin cable" or "thin-coated fiber", is a type of optical fiber used for indoor wiring. This type of cable usually has a thinner diameter and flexibility, making it easy to bend and pass through walls, making it ideal for use in scenarios such as homes and small offices. Butterfly drop cables are often used to introduce optical fiber from the backbone network to each room or device to achieve high-speed Internet, telephone and TV services;

[0004] Through the above content, we have mastered the actual application of optical fiber ribbon data cables during operation, and found that there are still some shortcomings. The existing optical fiber ribbon data cables are only connected by simple plugging and unplugging. Although such a docking method satisfies the mutual docking between cables, it is easy for the plug-in end to become loose or separated due to external factors or self-wear, and it is difficult to ensure the firmness of the cable after docking to the greatest extent. In addition, although the traditional butterfly-shaped introduction optical cable has the characteristics of easy branching and easy introduction, its own operation strength is insufficient, and it is easy to cause the cable to break due to pulling during installation docking or traction, which increases the loss of the cable;

[0005] Therefore, the present application proposes a pipeline butterfly-shaped data cable. Utility Model Content
