ABSTRACT:
The present invention relates to a novel fiber optic conduit-connector assembly for passing optical fibers between optoelectronic component housings. In one preferred embodiment, the conduit comprises a flexible, crush resistant and fluid resistant inner tube adapted for enclosing at least one optical fiber, a layer of electromagnetic shielding surrounding the inner tube, and an outer pressure tight layer surrounding the shielding layer. A connector adapted to allow at least one optical fiber to pass therethrough is fixedly attached to at least one end of the conduit by first stripping away the end portion of the outer layer of the conduit, inserting the inner tube of the conduit into one end of the connector and wrapping the shielding layer around the outer surface of the connector end. A thermofit ring is placed over the steel braiding and secures the braiding to the connector upon application of heat to the thermofit ring. A layer of heat shrink tubing is then placed over the thermofit ring and exposed inner layers of the conduit to provide a protective pressure proof layer. The other end of the connector is threaded to engage a standard coaxial cable entry port on an optoelectronic component casing.
