Heavy Duty Duct external cable is designed for LAN, MAN and WAN backbones. The cable can be installed into underground ducts using a cable sock. Constructed of “Dry” water-blocking materials and totally non-metallic for lightning immunity, the loose tube optical fibers enclosed are within a UV resistant PE sheath. The cable may be installed by blowing, compatible with INFRADUCT low friction liners of 32mm outer diameter.
