Device for fiber excess length stable control in optical cable loose tube

A system for stabilizing the fiber length of an optical cable loose tube comprising:

• an extruder for extruding an optical cable loose tube;
• a tractor for pulling an optical cable loose tube;
• a transitional conical shaped passive roller having an extrusion section portion and a tractor section portion,
• wherein the roller is configured to receive and wind an optical cable loose tube containing an optical fiber inside the loose tube at the extrusion section portion from the extruder,
• wherein the extrusion section portion of the roller has a larger diameter than the tractor section portion, and
• wherein the diameter from the extrusion section portion tapers to the smaller diameter at the tractor section portion;
• an optical cable loose tube containing an optical fiber;
• and
• a cooling water spray configured to spray water on the optical cable loose tube as it is wound around the roller,
• wherein the optical cable loose tube is pulled onto the roller by the tractor and wound around the roller from the extrusion section portion to the tractor section portion,
• wherein the water from the water spray cools the optical cable loose tube while it is winding around the roller.
