Optical fiber networks for public communications are moving toward the subscribers and therefore feeder optical cables with relative great amount of fibers are needed. A 120 fibers cable has been designed with ten UV curable acrilate coated fibers accommodate together inside each plastic loose tube, and twelve these tubes are stranded around a central strength member resulting in a high packaging density construction. A cable prototipe has been manufactured and some tests was made under conditions which simulate the situations found during installation and after due to hostile environments.
