Abstract
A method and apparatus are disclosed for fabricating an optical fiber communication cable having a metal containment tube and at least one optical fiber in static compression therein. The containment tube is preferably formed by applying a tensile load to a strip of metal and drawing the strip of metal through at least one forming die. Each fiber is inserted into the forming tube without the application of any significant tension. As a result, each fiber is in a substantially no-load condition at the same time that the strip is undergoing maximum plastic extension and said tube is undergoing elastic tension from the applied tensile load. Upon release of the tensile load, the tube will shrink and each fiber is placed into static compression.
