What is the role of LED UV in the forming process of ribbon fiber optic cables
An important link that cannot be ignored in fiber optic cable bundling
With the rapid development of fiber to the home (FTTH), the traditional loose layer twisted fiber optic cable used in the "eight vertical and eight horizontal" fiber optic trunk network in the early 1990s could no longer fully meet the fiber core density and cable diameter requirements of users
Large core, high-density, and high-capacity ribbon cables have gradually replaced traditional optical cables with their characteristics of high speed, fidelity, and access network, becoming the main transmission medium in application scenarios
In this transformation process, fiber optic ribbon has become the preferred form of large core optical cable due to its high density, small size, convenient splicing, and easy branching
To ensure high-quality core interconnection and save time and effort during the construction and splicing of ribbon cables, various manufacturers are exploring and improving their processes
In the process of forming ribbon fibers, in order to ensure a smooth surface, consistent length, and no bending deformation of the fiber, people often pay great attention to itControl of cleanliness of colored optical fibers, control of static electricity in colored optical fibers, control of pay off tension, control of coating mold size and placement position, and control of coating processWait
In fact, the control of UV curing process is also very important for improving overall quality
The front and back of the fiber optic ribbon coated with acrylic resin need to receive uniform UV irradiation to avoid the phenomenon of "semi-circular" or "semi-circular" shape after the ribbon is formed. Generally, careful adjustment is required before production to ensure that the fiber optic ribbon is in a uniform and consistent position under UV irradiation
Youwei Starlight Fiber Strap Products: The newly designed optical scheme with upper and lower contrasting light allows for uniform curing on both sides of the strap, ensuring that the strap is straight and does not deform or bend. Installation and operation are simpler and faster
Ensuring the cleanliness of quartz tubes during high-speed production (≥ 500m/min) has always been a challenge for the uniform solidification technology. High intensity production can easily cause the resin coated on the surface of the ribbon fiber to splash and adhere to the quartz tube wall, thereby reducing the transmittance of UV light and affecting the curing degree
Youwei Starlight Fiber Belt Products: Using high-performance axial fans can effectively reduce the deposition of attachments on the inner wall of the central tube. Meanwhile, adopting a modular design makes maintenance and replacement very convenient
When dust adheres to the surface of the reflector or there are burrs and spots, it can cause uneven distribution of reflected UV light, leading to curing cracks or uneven thickness of the coated acrylic resin, as well as poor flatness. It is necessary to regularly inspect and clean the reflector cover, and handle it gently when disassembling and assembling the curing oven cover to avoid scratches
Youwei Starlight Fiber and Belt Products: Adopting modular design, it has the characteristics of light weight, small size, and easy installation and maintenance, which can help reduce the problem of product defects caused by daily cleaning
The exhaust gas generated during the curing of resin lingers in the quartz tube for a long time, which is prone to sedimentation and causes the quartz tube to turn yellow or black; At the same time, in order to ensure the compatibility between the ink on the surface of the colored optical fiber and the acrylic coated resin, as well as the absence of bubbles or impurities embedded between the two, we usually fill nitrogen gas into the quartz tube to discharge the small amount of oxygen and waste gas generated during resin curing inside the quartz tube
Youwei Starlight Fiber and Belt Products: Adopting a brand new thermal design, it can effectively remove the heat generated by the chip while effectively discharging the tail smoke generated by the curing of the coating, without affecting the temperature of the central tube
