Abstract
Abstract A connector for connecting optical fibers together with a gap between their ends is proposed. It includes a body with a pair of walls, a pair of sleeves, a pair of plugs, and a pair of rod lenses carried by the sleeves. The rod lenses assure transmission of light with minimum loss in spite of the presence of a gap between the opposed ends of the optical cables.
