Abstract:
1. A line for manufacturing a fiber optic assembly having a tube containing at least one optical fiber, the line comprising: an extruder; a dynamic caterpuller system comprising a closed pipe, the dynamic caterpuller system located after the extruder along the manufacturing line; a pump in fluid communication with the closed pipe; and a liquid having a predetermined flow rate through the closed pipe imparted to the liquid by the pump, wherein, during manufacturing of the fiber optic assembly, the tube is extruded via the extruder and passes into the dynamic caterpuller system and the flow rate imparted to the liquid by the pump is different than a speed of the fiber optic assembly passing through the closed pipe such that a drag is imparted on the tube sufficient to form an excess fiber length of at least 0.05% on the at least one optical fiber relative to the tube.
