Abstract
Disclosed is an optical fiber coupling device which comprises an optical fiber, a coupling member to which the optical fiber is coupled, a coupling means for coupling the optical fiber to the coupling member, and an optical-fiber fixing section for fixing a part of the optical fiber. The optical fiber is coupled only at its forward end to the coupling member. A part of the optical fiber is fixed at a position separated from the forward end of the optical fiber by a specified distance. Thus, the stress applied to the fixed section of the optical fiber is absorbed into a portion of the optical fiber located between the forward end of the optical fiber and the fixed section of the optical fiber fixed by the optical fiber fixing section and which covers the specified distance, thereby to prevent the stress from being applied to the forward end of the optical fiber.
