ABSTRACT OF THE DISCLOSURE The present invention provides a method of forming an optical fiber joint between optical fibers having predetermined external reference surfaces for locating the guiding regions within the respective fibers, said method comprising: shaping an elongated glass preform to have a cross-sectional configuration with longitudinal surfaces which are large-scale complements of said external reference surfaces on the fibers to be joined, heating the shaped preform to a softened condition and then drawing the softened preform in a longitudinal direction to reduce the scale of said complementary surfaces so that the cross-sectional configuration of the drawn preform matches the cross-sectional configuration of said external reference surfaces on the fibers to be joined, cooling the drawn preform and placing the optical fibers to be joined thereon, with said external reference surfaces on the fibers engaging said complementary longitudinal surfaces on the drawn preform, and bonding said fibers to the drawn preform.
