1. A connectorized cable assembly comprising:
- a) a loose tube optical fiber cable including a cable unit, the cable unit including;
a plurality of loose, non-buffered optical fibers;
a strength yarn at least partially surrounding the non-buffered optical fibers; and
a jacket surrounding the strength yarn and the non-buffered optical fibers;
wherein the non-buffered optical fibers are loose with respect to all optical fibers surrounded by the jacket so that they have no particular fixed relative orientation; and
b) an optical fiber connector installed on the cable unit, wherein the strength yarn is directly secured to the connector to provide strain relief between the cable unit and the connector.

3. A method for forming a loose tube optical fiber cable, the method comprising:
-
forming a cable unit including; a plurality of loose, non-buffered optical fibers; a strength yarn at least partially surrounding the non-buffered optical fibers; and a polymeric jacket surrounding the strength yarn and the non-buffered optical fibers; wherein the non-buffered optical fibers are loose with respect to all optical fibers surrounded by the jacket so that they have no particular fixed relative orientation; and installing an optical fiber connector on the cable unit, including directly securing the strength yarn to the connector to provide strain relief between the cable unit and the connector. - View Dependent Claims (5, 28)

29. A connectorized cable assembly comprising:
-
a) a loose tube optical fiber cable including; a plurality of loose, non-buffered optical fibers; at least one inner strength yarn at least partially surrounding the non-buffered optical fibers; an inner jacket surrounding the inner strength yarn and the non-buffered optical fibers; an outer strength yarn surrounding at least a portion of the inner jacket; and an outer jacket surrounding the outer strength yarn and the inner jacket; wherein the outer strength yarn and the outer jacket surround only the at least one inner strength yarn and the inner jacket; and b) an optical fiber connector installed on the cable, wherein the inner strength yarn is directly secured to the connector to provide strain relief between the cable and the connector. - View Dependent Claims (30, 31)
