A micro splice protector for a fusion connection between a pair of optical fibers takes the form of a cylindrical sleeve of dimensions similar to that of the fusion splice itself, with an epoxy material used to encase the fusion splice within the sleeve. The sleeve is formed to exhibit an inner diameter only slightly greater than the outer diameter of the optical fibers, with the length of the sleeve typically formed to be only slightly longer than the stripped end terminations of the pair of fibers being spliced together. The cylindrical sleeve is formed of a rigid, but lightweight, material (e.g., stainless steel, fused silica) and an epoxy material is injected into the configuration to fill any gaps between the fusion connection and the inner surface of the sleeve. The result is relatively stiff fusion splice protector that is extremely small in size and well-suited for use in optical component packages where space is at a minimum.
