    Abstract: The purpose of the present invention is to provide, by a configuration or method different from conventional art, a coated optical fiber enabling reduced interface delamination between a glass fiber and a primary coating layer when the coated optical fiber is immersed in water, and a reduction of transmission loss increase. A coated optical fiber according to one embodiment of the present invention is provided with a glass fiber, a primary coating layer coated on the glass fiber, a secondary coating layer coated on the primary coating layer, and a colored layer coated on the secondary coating layer. The coated optical fiber is configured so that small water bubbles are generated substantially evenly within the primary coating layer when the coated optical fiber is immersed for 200 days in warm water of 60° C.
