Coil the fibers along the direction of the loose tube or the branching direction of the optical cable. A simulation technology from movies is used to predict coiling patterns in the lab. The world's fiber-optic network spans more than 550,000 miles of undersea cable that transmits e-mail, websites, and other packets of data between continents, all at the speed of light. The scientific fiber coiling method can make the fiber layout reasonable and eliminate fiber breakage caused by extrusion. Excessive bending angles will damage or even break the optical fibers, causing communication. One such advancement can be seen in the High-Precision Fiber Optic Cable Coiling and Automatic Winding Tool, which integrates both mechanical accuracy and intelligent control. Designed for 15–18mm wire materials, this system achieves speeds up to 200 meters per minute, powered by a robust 4kW motor. Disclosed is a method for producing an optical fiber coil including the following steps: a. symmetrical winding of an optical fiber around a shaft, the winding forming a pattern including a same number N of layers of each half of the optical fiber, one layer including a set of turns of optical. int is only on one side. Advantages: It avoids the confusion of optical fibers between fiber protection sleeve or between different branch.
