Vertical (dome) fiber optic splice closures are made of engineering plastics. The vertical fiber optic splice closure is used in CATV, telecommunications and fiber optic networks. Our vertical (dome) fiber splice closures feature high mechanical performance, great aging resistant ability, and excellent sealing performance against weather conditions. They are suitable for protecting optical fiber splices in straight through and branching applications. Related fiber optic trays and splice protection sleeves are supplied with vertical splice closures. These products can be used in aerial, duct and direct buried fiber optic cable projects..
