Abstract: An arrangement for supporting an optical fiber and related optical components in a raised position above a surface of a printed circuit board on which electrical components are mounted includes a support which defines an endless, oval raceway for receiving one or more optical fibers, legs mounted on the support and secured to the printed circuit board for supporting the raceway defining support above the surface of the printed circuit board a predetermined distance so that the support does not interfere with the electrical components mounted on the printed circuit board, and one or more ramps joined to the raceway and extending from the raceway substantially to the surface of the printed circuit board. The ramps provide support for the optical fibers over portions of the fibers where they are coupled to an opto-electronic transmitter or receiver mounted on the printed circuit board.
