The principle and solutions of fiber optic bending

October 17, 2023

Fiber optic is a slender light-conducting material made of high-purity glass or plastic that enables the transmission of light through internal reflection. In fiber optic transmission, light typically propagates along a straight path, but a series of optical phenomena occur when the fiber optic bends.


Addressing fiber optic bending issues involves considering the following aspects:


Choosing the appropriate type of fiber optic: When designing and installing a fiber optic network, it is possible to select fiber optic types that are suitable for bending. Flexible fiber optics usually have higher bend tolerance, allowing them to work on smaller radius curves without causing light loss. Therefore, choosing flexible fiber optic is an important step in reducing fiber optic bending issues.


Controlling the fiber optic's bending radius: By controlling the bending radius of the fiber optic, it is possible to minimize bending loss. Generally, the larger the bending radius of the fiber optic, the lower the bending loss. During fiber optic cabling and installation, it is necessary to avoid excessive bending, particularly when the bending radius is smaller than the fiber optic's allowed bending radius. Proper equipment and techniques can be used, such as fiber optic bend protection sleeves and fiber optic strain relief devices, to ensure the fiber optic's bending radius is appropriate.


Avoiding mechanical stress: Fiber optics are prone to mechanical stress in applications, such as tension, pressure, and twisting. These mechanical stresses can cause bending deformation and damage to the fiber optics, resulting in loss of light transmission. Therefore, during fiber optic cabling and installation, it is important to avoid applying mechanical stress and use suitable fiber optic protection devices and brackets to reduce the impact of mechanical stress on the fiber optic.


Nanjing Hecho supports custom fiber optics, and by selecting the appropriate fiber optic type and controlling the fiber optic's bending radius, it is possible to effectively address fiber optic bending issues, improving the reliability and performance of fiber optic transmission, and meeting different customer usage requirements.
