ABSTRACT:
An optical fiber aligning member includes at least two grooved substrates, each of which has a first main surface in which optical fiber aligning grooves and at least two first positioning grooves are formed and a second main surface opposite the first main surface in which at least two second positioning grooves are formed. The grooved substrates are laminated on top of each other in a manner so that each grooved substrate is alternately turned over. First positioning pins are positioned in the first positioning grooves and second positioning pins are positioned in the second positioning grooves for aligning the alternating grooved substrates. In a method for making the optical fiber aligning member, the fiber aligning grooves and the positioning grooves are formed in the surfaces of a flat plate. The grooved substrates are formed by dividing the flat plate at an angle perpendicular to the grooves. The grooved substrates are stacked alternately so that grooved substrates that were adjacent each other in the flat plate are stacked adjacent each other in the optical fiber aligning member with their positioning grooves opposing each other.
