A key topic to know is how does bending affect the optical fibers cables. This is especially the case with regard to keeping them operational. Excessive bending or twisting can cause the fibers to break, but the maximum bend agreed upon in the industry is at least 1.5 times the diameter of the cable to avoid attenuation, especially with tight-bend cables. In this article we learn about why we need to bend fiber, how much we can bend cables, the difference in possible cable layouts, and why the bending radius matters.
Optical fibers are special cables that transfer light. They consist of two principal elements: a core and a cladding layer. The light goes into the core. Light travels through the fiber by bouncing of the walls of the core. This bounciness is referred to as total internal reflection. It allows the light to travel long distances without losing strength.
However, when fiber optic cables are used, it is important to bend them gently. Avoid making sharp bends. Use appropriate tools and methods to preserve the fibers. (Use a bending tool or mandrel if you can. These tools are used to bend the fibers smoothly without breaks and kinks.
It is crucial to be aware of the limitations of optical fiber cables. They can flex, but there’s a limit to stretching. A too-sharp bend in a fiber optic lead will either result in a signal loss or may even break the fiber altogether. This can cause your network to stop functioning. Refer to the manufacturer's instructions on how to bend optical fiber cables to prevent issues.
This is particularly important for getting your bending radius correct. Bending radius is the smallest curve optical fiber can make without being damaged. Always adhere to the manufacturer specified bend radius. This keeps the fibers in shape and working well. However, by following this guide, you can ensure that your network will last a very long time.
Optical fiber cables can be bent in different ways. Examples are coiling, looping, and mandrel bending. There are pros and cons to each style. So selecting the right one for what you require is very essential. Several tools and accessories are available that make it easy to make accurate bends in the optical fiber cable.
