Description

Technical Field

[0001] The utility model relates to the technical field of a wire drawing mechanism for laying optical fibers, in particular to a wire drawing mechanism for laying optical fibers. Background Art

[0002] Laying optical fiber is a critical step in building high-speed communications networks. Optical fiber cables consist of a core, cladding, and sheath. The core is the most crucial component, used to transmit optical signals. It is primarily made of high-purity silica and typically has a diameter ranging from a few to tens of microns. For example, the core diameter of single-mode optical fiber is generally around 9-10 μm. This type of fiber is used for long-distance, high-bandwidth communications. The cladding surrounds the core and has a lower refractive index than the core, allowing light signals to propagate through the core via total internal reflection. The sheath protects the optical fiber from environmental damage and is typically made of materials such as plastic, offering waterproof, moisture-proof, and abrasion-resistant properties.

[0003] During the optical fiber laying process, it is necessary to pull the light in overhead laying, pipeline laying and direct burial laying. In pipeline laying, due to the narrow and long pipeline, traditional traction requires the use of a traction rope connected to a threader to pull the traction rope through the pipeline. This method cannot well protect the optical fiber traction part and is not applicable to pipelines of different sizes within a certain diameter range. There is also a risk of the traction rope breaking, which causes certain inconveniences. Based on this, a pulling mechanism for optical fiber laying is proposed. Utility Model Content
