ABSTRACT:
After a number of optical fibers are inserted into a tubular member of a shape memory alloy, the tubular member is returned to its memorized shape by heating to reduce a cross-sectional area of a reception space of the tubular member, thereby uniting the optical fibers received in the tubular member. In a modified form of the invention, a number of optical fibers are inserted into a reception space between two tubular members at least one of which is made of a shape memory alloy, and then the one tubular member is heated to be returned to its memorized shape to reduce a cross-sectional area of the reception space between the two tubular members, thereby uniting the optical fibers. In another modified form of the invention, a number of optical fibers are inserted into a reception space formed between an inner periphery of a tubular member and a partition plate of a shape memory alloy, and then the partition plate is heated to be returned to its memorized shape to reduce a cross-sectional area of the reception space, thereby uniting the optical fibers.
