An apparatus for producing bends in optical bends in optical fibers comprising a pair of plates hingedly connected along one edge of each of the plates so that the plates may lie in face-to-face contact and may be hingedly separated, means defining a cavity between the plates when in face-to-face contact, the cavity having two portions for receiving lengths of a fiber on opposite sides of a bend to be formed, the portions being joined at an apex section, means defining an opening into the cavity at the apex section, a fiber channel in each of the portions, the fiber channels being mounted in the portions for relative movement in the cavity to a desired bend angle while the apex of the desired angle is positioned at the opening in the apex section, and pulling means for acting on an optical fiber in the channels when the plates are in face-to-face contact and thereby positioning a fiber at the desired angle whereby the apex of the bend of the fiber is accessible through the opening; several variations of the apparatus are disclosed along with a method for producing bends in optical fibers using the foregoing apparatus for avoiding signal loss or attenuation through the bends.
