Fiber-optic cable OKL-T/C for installation in cable ducts, tubes, tunnels.
Fiber-optic cable OKL-T/C is designed for installation in cable ducts, tubes, tunnels. OKL-T/C with flame retardant jacket is designed for installation according to exclusive standards of fire safety.
Cable core is a tube of natural color. Optical fibers are placed inside the tube. Interstice inside cable core is filled with hydrophobic filler. Fiber glass yarns are formed around cable core. An additional jacket of high density polyethylene is extruded over the fiber glass yarns. The outer jacket is made of high density polyethylene. In case of exclusive standards of fire safety cable jacket is made of halogen free flame retardant (HFFR) compound. Cable jacket includes additional strength components as a steel wire. In case of number of fibers exceeds 12 ring marking is used and/or bundling with identification yarns.
