144 Core Dome Joint – High-Capacity Mechanical Fibre Enclosure

The 144 Core Mechanical Dome Joint is a heavy-duty fibre optic splice closure designed to accommodate high-volume fibre networks. With 6 cable inlets and mechanical sealing, it supports up to 144 fibre core splices, making it ideal for backbone, distribution, and access networks that demand flexibility, durability, and fast deployment.

Key Features

• Capacity: Supports up to 144 fibre core splices
• Sealing Type: Mechanical, no heat shrink tools required
• Inlet Ports: 6 cable inlets for flexible network branching
• Material: High-strength UV-resistant plastic housing
• Enclosure Type: Dome design with base clamp sealing
• Ingress Protection: IP68-rated for complete dust and water resistance
• Mounting: Suitable for aerial, duct, manhole, or wall-mount installations

High-Capacity Fibre Network Expansion

Engineered for large-scale FTTx rollouts, metro core networks, and data backbones, this 144 core dome joint offers maximum flexibility. The six inlet design supports ring, tap-off, and cross-connection topologies—critical for managing high-density fibre traffic in growing urban networks.

Efficient Mechanical Splicing

Designed for tool-free fibre preparation and sealing, the joint simplifies on-site installations. It uses mechanical clamps and rubber grommets to secure cables, eliminating the need for heat guns or shrink tubing. Internal splice trays provide tidy fibre management, supporting either single or ribbon fibre configurations.

Applications

• FTTH and FTTB distribution networks
• Long-haul and metro fibre deployments
• Railway, mining, and industrial communication systems
• Municipal and service provider infrastructure
• High-density data centres and ring architectures

Built to Withstand Extreme Conditions

Sealed to IP68 rating, the closure withstands flooding, dust, UV exposure, and wide temperature fluctuations. This ensures long-term performance even in underground vaults, poles, or rooftop enclosures exposed to the elements.
