What effect does improper bending of an optical fiber have on its tensile strength?

Improper bending of an optical fiber can significantly decrease its tensile strength. When a fiber is bent beyond its specified minimum bend radius, it can create points of stress within the fiber material. This stress can lead to micro-cracks or damage in the fiber core and cladding, ultimately compromising the fiber's structural integrity.

Additionally, excessive bending can disrupt the alignment of the light path within the fiber, leading to increased signal loss and reduced performance. Therefore, maintaining the proper bend radius is crucial for ensuring the strength and overall functionality of the optical fiber. Properly installed fibers will have an optimal tensile strength, ensuring durability and reliability in the network.
