Fiber cutting, an important fiber processing technology

Fiber optic cutting is an important technique in fiber optics. It involves precise cutting of fiber optic ports through specific tools and methods to obtain a clean surface. Here is a detailed explanation of fiber optic cutting: 1. Definition of fiber optic cutting. Fiber optic cutting refers to cutting fiber optic ports to obtain a clean, flat surface that meets specific requirements. This surface usually needs to be very flat, at least in the core area of the fiber, sometimes it needs to be kept flat throughout the cross section, and sometimes it needs to be perpendicular to the fiber axis or have a definite angle to the fiber axis. 2. Purpose of fiber optic cutting. The main purpose of fiber optic cutting is to prepare for the connection, welding or incident and extraction of optical signals of the fiber. A clean, flat fiber optic port can reduce the scattering and reflection of optical signals at the connection point, improve the transmission efficiency of optical signals, and reduce signal attenuation. III. Tools for fiber optic cutting Fiber optic cutting is usually carried out using a fiber optic cutting knife. Based on physical cutting and positioning technology, the fiber optic cutting knife adopts a high-precision guide blade positioning system, and controls the high-precision blade for cutting through mechanical devices. In addition, for specific applications or high-precision requirements, other cutting equipment such as laser cutting machines may also be used. IV. Steps for fiber optic cutting The steps of fiber optic cutting usually include: Preparing the fiber: Use stripping pliers to remove the coating layer of the fiber surface, and reserve a certain length of bare fiber. Cleaning the fiber: Wrap the fiber with dust-free paper dipped in alcohol, and wipe the fiber to ensure the quality of the cutting surface. Placement of optical fiber: Place the cleaned optical fiber in the fiber carrier groove of the optical fiber cutting knife, fix the optical fiber, and ensure that the end face of the optical fiber is suitable for the position of the cutting blade. Cutting optical fiber: Push the slider through fine-tuning, so that the blade cuts the optical fiber. After the cutting is completed, the end face of the optical fiber should be flat and free of burrs. Five, Precautions for optical fiber cutting Blade selection and maintenance: The blade material of the optical fiber cutting knife has a great impact on the cutting quality. Blades with high hardness and wear resistance should be selected, and the blades should be cleaned and replaced regularly to maintain the quality of the cutting surface. Cutting angle and accuracy: According to the application requirements, the cutting angle may need to be strictly controlled. At the same time, cutting accuracy is also a key factor affecting the quality of optical fiber connection and transmission efficiency. Therefore, the accuracy of cutting angle and accuracy should Safe operation: Sharp fiber fragments may be generated during the fiber cutting process, which may cause harm to the human body. Therefore, appropriate protective equipment should be worn during the operation, and to ensure the cleanliness and safety of the work area. Six, the application of fiber cutting. Fiber cutting is widely used in fiber optic communication, fiber sensing, fiber lasers and other fields. In fiber optic communication, fiber cutting is a key step to realize fiber connection and welding; in fiber optic sensing, fiber cutting can prepare the fiber end face for sensing; in fiber lasers, fiber cutting is used to prepare the output end face of the laser. To sum up, fiber cutting is an important fiber processing technology, which involves multiple aspects and details. With the right tools, steps and precautions, high-quality fiber cutting surfaces can be obtained, providing strong support for fiber applications.
