Abstract: Apparatus for aligning an article, for example an optical fiber, relative to a datum, for example a Vee groove, another fiber, or a light source, includes means for manipulating the article in two intersecting directions. The manipulating means comprises a part fixed relative to the datum and a first arm coupled to the fixed part by a hinge. A second arm is coupled by a second hinge to the first arm at a position adjacent the first hinge. Adjacent its proximal end, the second arm carries a mount for the fiber. The arrangement is such that pivoting of the first arm displaces the mount in one of the intersecting directions. Pivoting of the second arm displaces the mount in the other of the intersecting directions. Preferably, the fixed part, hinges and arms are integral with one another, substantially eliminating play and backlash. The apparatus affords precise manipulation of articles such as single-mode optical fibers prior to and during fusion splicing.
