Abstract: A cylindrical sleeve connector for mounting ferrules retaining optical fibers therein is formed with a plurality of perforations arranged in a given pattern so as to be elastically deformable within in a specified elastic region. The sleeve connector is produced, using electroforming process, on a cylindrical electroforming mandrel comprising a conductive rod with external surface texture that is equivalent to required internal surface texture of the sleeve connector and a non-conductive layer formed on the conductive rod so as to provide non-conductive segments identical in configuration with the perforations and arranged in conformity with the given pattern of perforations of the cylindrical sleeve connector.
