Outdoor Fiber Splice Closure
Model: GL-H4-C1 Horizontal Outdoor Fiber Splice Closure
The GL-H4-C1 inline outdoor fiber splice enclosure facilitates cable linking, branching, distribution, and storage. Its unique sealing method, protected by a national patent, ensures superior sealing performance.
- Product Introduction
4 Cable Ports Outdoor Fiber Splice Closure
This outdoor fiber splice closure is universal and accommodates non-cut cable inlets. This model features four cable ports and can be used for various optical fiber cable splicing and branching applications. It is suitable for aerial, duct, and direct burial installations. The closure ensures secure fiber storage and supports connections for both armored and non-metallic cables. Designed to protect cables and fibers from environmental damage, it also allows for cable branching when required.
The specially engineered material offers excellent impact resistance, aging resistance, and low-temperature tolerance, operating effectively in temperatures ranging from -40℃ to +65℃ without degradation. The outdoor fiber splice closure includes a unique sealing structure compatible with cables ranging from Ф10mm to Ф22mm in diameter, eliminating the need for additional accessories.
