FTTH 1 2 4 Core GJYXFCH G657A1 Fiber Optic Drop Cable Indoor Outdoor
Product Overview
Outdoor self-supporting steel wire drop fiber optic cable available in 1, 2, 4, and 6 core configurations with G657A1 fiber. This FTTH outdoor drop cable is constructed with two single mode fibers and protected by a dielectric strength member made of three steel wires and a LSZH outer jacket. Designed for outdoor installation, the cable is well suited for connections between the dome closure and small dwelling units, warehouses, and independent villas.
