Single Mode Direct Burial Fiber Optic Cable 48F

Part Code: 55031-048


The Direct Burial Outdoor Fiber cables are PBT Multi Loose Tube with colored fiber cores. The constructions are of Double Sheath, Double Armored with FRP/ Steel CSM options and tape/ yarns for water blocking. These cables are prefect for direct burial applications. The Multi Loose Tube consist of 6 to 24 cores per tube with a maximum capacity of 288 fiber cores. Inner and Outer sheath are made of HDPE material, having ECCS armoring for both layers where the outer armor is provided with Anti-Rodent properties.
