Abstract
This invention is an improved apparatus and method for making fiber optic communication cables by cutting accurate helical grooves in a layer of insulation surrounding the surface of a strength member, and inserting the fiberglass conductors into the grooves with fillers and spacers around and between the glass conductors to protect them from damage. Helically wrapped binders and heat barrier tapes may be wrapped over the assembly with any additional binder threads or tapes as may be necessary to hold the heat barrier in place.
