- Product Introduction
Product Overview
GL-5601 is a member of the dome series of Fiber Optic Splice Closures. This model features four small circular cable entry ports and one large circular port for express cables. The sealing components are made of silicone. The cables and closure are mechanically sealed using compression from plastic screws and a circular plastic hoop. It is suitable for various branch connection methods, including branching and splicing of uncut cables. The sealing performance is excellent, and the closure is easy to install. It is mainly used for the straight-through and branch connection of the overhead, pipeline, direct buried and other laying methods of various structural optical cables.


Key Features
The fiber optic splice closure offers a comprehensive set of advantages centered on providing robust, stable, and durable protection for cable splicing points. Its key strengths include exceptional sealing and protective performance, effectively resisting the intrusion of moisture, dust, and other harmful substances, with an protection rating typically up to IP68 . The closure's sturdy shell, made from high-strength engineering plastic, boasts excellent corrosion resistance and can withstand significant axial tensile force and extreme temperature variations .
Furthermore, it features an ingenious internal structure and maintenance-friendly design. The splice trays, which can be stacked, allow for organized storage of fiber splices and excess fiber, offering a rational layout that facilitates future expansion, maintenance, and reuse . Finally, its wide applicability and reliability are evident in its suitability for various cable laying methods such as aerial, duct, and direct burial, supporting both straight-through and branch connections. With capacities ranging from 4 to 288 cores, it meets diverse communication needs from user access points to backbone networks, ensuring stable signal transmission with low loss .
