Have you ever experienced WIFI suddenly broken, have you experienced repeated restarts, still feel that the speed card is slow? The reason for these problems is that in addition to the router itself, there may be problems with your fiber optic cable. The propagation of light in an optical fiber is mainly based on the principle of total reflection. When the vertical ray end of the ray is incident and coincides with the fiber axis, the light travels forward along the axis. If you bend too much, it will cause some of the light to fail to pass normally, which will cause the optical power to drop, resulting in poor quality. The speed is slow. The radiation loss fiber produced by fiber bending is soft and can be bent, but after bending to a certain extent, although the fiber can guide light, it will change the light transmission path. The transmission mode is converted into a radiation mode, so that a part of the light energy penetrates the cladding layer or passes through the cladding layer to become a radiation mode and is leaked outward, thereby causing loss. When the bending radius is larger than 5 to 10 cm, the loss caused by the bending is negligible. So, what should we do once the fiber is damaged? Let's analyze the Inline Closure manufacturer below. Once the pipeline is broken, we need the help of the fiber fusion splicer. Generally, when we say something is broken, we need to repair it. The fiber has a loss, not called repairing the fiber, it is necessary to weld the fiber. The damage of the optical fiber caused our home network to be slow or small. The difference between the home and the enterprise fiber is that the enterprise fiber is superior to the fiber used in the home in terms of transmission speed and resistance to breakage. When you walk into a data center, you will find that there is not only fiber optics but also a more conspicuous cable. The optical cable is also considered to be an optical fiber. The inside of the optical cable is also composed of the multi-core optical fiber so that it is thicker and has a stronger transmission capability.
