Abstract
An optical fiber coupler comprising a glass sleeve having a link piece of single material glass optical fiber having a refractive index higher than the sleeve mounted in a central section of the sleeve. The central section of the sleeve is collapsed to secure the link piece therein, leaving portions of the sleeve beyond the link piece of sufficient cross-section to freely receive optical fibers therein to be optically coupled. An index matching adhesive is used to secure the fibers in the sleeve abutting the link piece.
