Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication cable processing, in particular to a constant-tension paperless drum glass fiber yarn pay-off structure. BACKGROUND

[0002] With the fifth generation mobile communication system (5G) moving towards higher speed, lower latency, lower power consumption. 5G bearer network architecture is also different from the 4G bearer network architecture, the 4G bearer network architecture usually adopts BBU (remote radio frequency module) and RRU (remote radio frequency unit - usually custom'remote unit') two-level architecture, while 5G will evolve into DU (distributed unit), CU (centralized unit) and AAU (active antenna unit) three-level structure, the corresponding bearer network architecture can be decomposed into front-haul, middle-haul and backhaul networks, and more wireless radio frequency remote optical cables are needed in the DU and AAU front-haul section to support network construction. The main feature of the wireless radio frequency remote optical cable is high-strength non-metallic reinforcement, and glass fiber yarn (commonly known as glass fiber yarn) is the most commonly used non-metallic reinforcing material for wireless radio frequency remote optical cables. It not only ensures the stability of optical fiber transmission performance, but also has the advantages of light weight, flame retardant, easy to peel, high flexibility, corrosion resistance, high temperature resistance, low moisture absorption and other excellent properties.

[0003] However, the traditional optical fiber cable adopts paper drum glass fiber yarn pay-off preparation, and the price of the paper drum glass fiber yarn is expensive, and the production cost of the raw materials for the preparation of the optical fiber cable is high. Moreover, the glass fiber yarn has unstable pay-off tension when using the traditional pay-off mechanism. The glass fiber yarn has extremely small single filament diameter and is hard and brittle, and has poor wear resistance. The special flat structure of the glass fiber yarn leads to the phenomenon of glass fiber single filament twisting during the pay-off process, which causes the optical cable to have fluctuating outer diameter, wall thickness deviation, and uneven internal arrangement, resulting in deformation of the optical fiber due to human or device pressure during subsequent construction process. In severe cases, the optical fiber may be broken, which affects the roundness of the outer surface of the optical cable and reduces the mechanical properties of the optical cable, thereby reducing the communication quality.
