Joint Enclosures
FIBER OPTIC JOINT CLOSURE DOME TYPE (MOD-J288D)
The MOD-J288D Dome Type Fiber Optic Joint Closure is designed to provide superior protection and long-term reliability for large-capacity optical fiber splicing in demanding field environments. Built for use in aerial, duct, and underground networks, this closure offers robust resistance against water, dust, and environmental stresses, ensuring consistent performance and durability.
With its high-capacity dome structure, the MOD-J288D supports up to 288 fibers while maintaining an efficient and compact footprint. Its versatile design accommodates multiple cable diameters and types, enabling easy adaptation across different network architectures.
Engineered for both single fiber and ribbon fiber applications, this closure is ideally suited for backbone, feeder, and distribution networks where high fiber counts and long-term stability are essential. The MOD-J288D combines ease of installation, expandability, and strong sealing performance, making it a reliable solution for modern fiber optic infrastructures.
