The Soft Tube Cable ‘Slim’ range (STC-S) has been designed for optical backbone and distribution networks. Its light and robust dielectric structure, its low-friction HDPE sheath and its optimized diameter make these cables perfectly suitable for installation in ducts by pulling, floating or air-blowing. They have been designed to meet the requirements of the French XP C 93-850-3-25 standard.
