ABSTRACT:
A first optical fiber support member (30) is held in a first fixture (35) having a first alignment pin (40) extending therefrom perpendicularly to an optical fiber array (32) and also having a first alignment aperture (43). A second support member (31) is held in a second fixture (37) having a second alignment aperture (41) and a second alignment pin (42) extending therefrom perpendicularly to the optical fiber array. When the two support members are clamped on opposite sides of the optical fiber array, they are aligned by engaging the first alignment pin (40) with the second alignment aperture (41) and engaging the second alignment pin (42) with the first alignment aperture (43). With the support members clamped, fluid adhesive is applied through an aperture (61) to bond the support members (30, 31) and optical fiber array (32) together. The first and second support members (30, 31) are made of plastic and are made by plastic molding. As a consequence, a third alignment projection (50 ) and a third alignment aperture (52) can be made in the first support member (30), and a fourth alignment projection (51) and a fourth alignment aperture (53) can be made in the opposing face of the second support member (31). These projections are much smaller than the first and second alignment pins, and when the support members are clamped together, engagement of the third alignment projection with the fourth alignment aperture and engagement of the fourth alignment projection with the third alignment aperture gives a finer and more precise degree of alignment.
