ABSTRACT:
An optical module comprises a capillary in which first and second optical fibers are connected. The first optical fiber is aligned through a lens to an optical device, and the second optical fiber functions as a pigtail cord connected to an external optical fiber. The first optical fiber is a TEC (thermal expand core) fiber having an end portion whose core diameter is larger than that of the other portion thereof, and the first optical fiber is a normal optical fiber which has a uniform core diameter smaller than the core diameter of the TEC fiber.
