ABSTRACT:
A pre-connectorized loose tube cable protects the optical fibers as the fibers are being routed from the end of an outer sheath to the fiber distribution shelf. The pre-connectorized loose tube cable has a plurality of flexible tubes which are connected to a respective plurality of buffer tubes. The flexible tubes are securely attached to the ends of the buffer tubes and to the pre-connectorized loose tube cable by a capping epoxy and by heat shrinks. The flexible tube has a wall thickness which is greater than the minimum bend radius for the fibers. With such a wall thickness, the fibers are not bent past their minimum bend radius, and thus do not break, even if the flexible tube is bent up to an angle of one hundred eighty degrees.
