A tube and a pair of optical frames are employed within an optical
connector mount to optically couple two or more optical elements. The
optical frames are used to mount the optical elements on the optical
connector mount, and the tube is adjoined to the optical frames to allow
and maintain the optical alignment of the optical elements. The adjoining
of a tube to one of the optical frames involves either a seating and
locking of a spherical segment of the tube within a tube seat of the
optical frame, or a seating and locking of a spherical segment of the
optical frame within a frame seat of the tube.
