How is fiber quality evaluated by applying a continuously increasing tensile load?
Applying a continuously increasing tensile load to an optical fiber is a fundamental method to evaluate its mechanical quality and determine its tensile strength. This process involves steadily increasing the axial force on the fiber until it fractures. The maximum load the fiber can withstand before breaking is its ultimate tensile strength. This test provides critical data on the fiber’s resistance to mechanical stress, its reliability, and its suitability for applications where it will experience tension.
For applications requiring high mechanical resilience, OFSCN provides various products manufactured with robust optical fibers. For instance, the OFSCN® Polyacrylate Fiber Bragg Gratings / Fiber Bragg Grating Strings (bare) are produced using high-quality OFSCN® G.652D or G.657 optical fibers, designed to offer reliable performance within a strain range of up to 10000µε. Additionally, specialized fibers such as OFSCN 200 Polyimide Optical Fiber and OFSCN 300 Polyimide Optical Fiber are engineered for enhanced mechanical and thermal stability in demanding environments.
