Abstract
An optical module includes first and second fiber units that hold end portions of first and second optical fibers, and first and second collimators disposed between these fiber units and having first and second lenses, respectively. End faces of the first and second optical fibers are disposed on imaginary circumferences on the end faces of the first and second fiber units. Laser light beams from the end face of the first optical fiber are collimated by the first lens and then focused by the second lens, and enter the end face of the second optical fiber that is disposed diametrically opposite to the first optical fiber with respect to the center axis of the optical module.
