Fiber optic cable OKLs with stainless steel central tube for installation in cable ducts.
OKL is designed for installation in tubes, cable ducts, tunnels. OKLs from flame retardant materials is designed for installation according to exclusive standards of fire safety.
Cable core is stainless steel tube. Optical fibers are placed inside a tube. Interstice inside cable core is filled with hydrophobic filler. The outer high density polyethylene jacket is extruded over the core. In case of exclusive standards of fire safety cable jacket is made of flame retardant halogen free (HF) compound. In case the number of fibers exceeds 12 ring marking is used and/or bundling with identification yarns.
