CommScope's 8107357/DB (D-012-LN-8W-F12NS, Millennium part #12920) is a non-armored, all-dielectric fiber optic cable built with a stranded loose tube design and 12 fibers per subunit using G.652.D and G.657.A1 singlemode fiber. The black polyethylene jacket is rated from -40C to +70C, supporting reliable performance whether the cable is aerially lashed to messenger strand or direct buried. Its dielectric construction makes it well suited for routes that require electrical isolation from power infrastructure.
