Question

why do you need to bent fiber​

Answer 1

Answer:

Maintaining proper bend radius is important in preventing service calls due to damage and signal loss in your optical fiber. Bend radius is the curvature an optical fiber can bend without damage or shortening its lifespan via kinking. The smaller the rated bend radius, the more flexible the fiber.

Answer 2

Explanation:

Explanation:Bend insensitive fiber has a refractive index trench, or a ring index of refraction material. This reflects the lost light caused by the bend so that it comes back into the fiber's core, minimising data loss.
