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.

Application

  • Branching and straight-through joints

  • Pole-mount, wall-mount, and manhole installations

  • Buried and aerial fiber optic networks

  • Suitable for all high-speed transmission networks (FTTx, metro, backbone)

  • Large dome size, ideal for high-capacity fiber networks

  • Suitable for network expansions and backbone projects requiring large splice counts

Features & Benefits

  • Outdoor dome-type closure designed for up to 288 fibers with modular splice trays

  • Large-capacity housing suitable for backbone, feeder, and distribution networks

  • Made of PP+GF (polypropylene + glass fiber) for UV resistance, flame retardancy, and long-term durability

  • 4 inlet + 4 outlet ports for versatile cable management (supports multiple diameters)

  • IP68-rated sealing with mechanical clamp + heat-shrink system for maximum waterproof and dustproof protection

  • User-friendly design for fast installation, cable routing, and easy maintenance

  • Expandable splice tray system supports up to 12 trays (24 cores each) for flexible fiber management

  • Compatible with all optical cable types – single fiber, loose tube, micro cable, and ribbon fiber
