An optical module includes a base and a plurality of cooling fins mounted to the back surface of a printed wiring board used to support a number of opto-electronic devices. To optimize heat removal; the fins are mounted on the back surface in alignment with the opto-electronic devices mounted on the front surface. The module also includes a number of fiber-optic management features which are mounted on the wiring board or materially integrated with the base and cooling fins. By combining fiber-optic management features with a heat sink, on the opposite side of board-mounted opto-electronic components, the optical module achieves increased packaging density and functionality on a per volume basis compared with its conventional counterparts.

A fiber-optic cable guide includes first and second guide walls, one or more base support elements for connecting the guide walls, and a number of securing elements which extend from the guide walls along a top portion thereof. Each securing member preferably has a length which is shorter than the spacing between the guide walls. This difference in length substantially corresponds to the diameter of a fiber-optic cable. A fastener may be included on a bottom surface of one or more of the guide walls for attaching the guide to a mounting surface, which may be a printed circuit board. Furthermore, the guide walls may be conformed to traverse any desired path along the board.
