ABSTRACT:
An optical fiber has a core structure and a first coating layer covering the core structure. The optical fiber, after being twisted, is covered at its outer side with a second coating layer. The second coating layer is higher in Young's modulus than the first coating layer. As a result, the twisting of the optical fiber is stably retained by the second coating layer. Further, an outer force coming from the second coating layer is absorbed by a soft first coating layer, so that no compressive force acts on a core and cladding in the optical fiber.
