Our Outdoor (OSP) Gel-Filled Pre-Terminated Fiber Optic Cable Assemblies are rated for almost all outdoor applications. This cable is suitable for underground installation inside conduit and pathways that are subjected to wide temperature variations or water infiltration, overhead lashed to a guy wire, or secured to a building or other permanent outdoor structure. This cable is UV & Crush resistant and includes water blocking gel. Our outdoor (OSP) pre-terminated fiber optic assemblies are perfect for headend termination to a fiber backbone and intra-building backbones. If installing in conduit we recommend using at least a 2" diameter conduit to accommodate for the assembly breakout.
