Application: Subscriber cable for FTTH networks, has small size and high flexibility. Used as a distribution cable for cabling inside buildings, in cable trays, in cable ducts, pipes, and tunnels, as well as for cabling on external facades of buildings.
The cable has a few optical fibers. The fibers and strength members are covered with overall jacket. Two strength members of steel wires protect the cable against mechanical stress. The cable jacket is made of a flame retardant halogen-free polymer material with reduced smoke and gas emission. The maximum possible count of optical fibers in the cable is 8.
