Description
FOSC-H4 Series is an inline fiber optic splice closure designed for outdoor fiber cable splicing, branching, and protection in FTTx access and distribution networks. The closure uses a horizontal in-line structure with 4 inlet and 4 outlet cable ports, making it suitable for straight-through cable routing, branch connections, and multi-direction fiber distribution.
Built with PP+GF housing, IP68-rated protection, and mechanical screw sealing, FOSC-H4 provides a durable and reusable closure solution for aerial, pipeline, and direct-buried fiber optic installations. With up to 48F splice capacity and 24F splice tray capacity, it is suitable for medium-capacity outdoor network connection points where reliable sealing, mechanical strength, and easy maintenance are required.
