Joint Enclosures
FIBER OPTIC JOINT CLOSURE DOME TYPE (MOD-J03D)
The MOD-J03D Dome Type Fiber Optic Joint Closure is engineered to provide secure and long-lasting protection for optical fiber splices in challenging outdoor and underground environments. Designed for use in aerial, duct, and direct-buried networks, this closure offers a highly reliable, waterproof, and dustproof housing that ensures stable performance over time.
Its dome-shaped structure delivers a balance of high splice capacity and compact design, allowing for efficient installation in limited spaces. The flexible configuration supports multiple cable types and diameters, making it suitable for a wide range of network topologies.
With compatibility for both single fiber and ribbon fiber applications, the MOD-J03D is ideal for backbone, feeder, and distribution networks, providing network operators with a robust and versatile solution that reduces maintenance time and enhances long-term reliability.
