Abstract: A conduit for receiving lengths of fiber optical cable, which enhances light emission and transmission within the cable by substantially reducing an air gap located between a polymeric core and an outer cladding of the fiber optical cable. The conduit of the present invention has a retaining member that defines a first channel adapted to receive the fiber optical cable and a base member that defines a second channel adapted to receive the cable. The retaining member is mounted with the base member, such that the cable is retained within the first and the second channels and a compressive force is exerted on the cable, which substantially eliminates the gap between the core and outer cladding. Furthermore, the conduit of the present invention supports and guides the cable and facilitates the installation thereof.
