Dome Fiber Optic Splice Closure

HONE dome-type closures support various cable configurations and capacities, making them suitable for trunk and distribution line splicing. Tool-less sealing or mechanical sealing options make installation fast and efficient.

1. Structure & Design

• Shape: Vertical/dome shape for compact design and high sealing performance.

• Material: High-strength polypropylene (PP) or PC+ABS with UV resistance and flame retardant properties.

• Sealing Method: Mechanical seal (silicone rubber gasket) or heat-shrink seal.

• Cable Ports: Usually 4 to 6 round ports; customizable based on your needs.

• Capacity: Supports 12–288 core fibers (depending on tray count).

• Splice Trays: Modular stacking design, hinged for easy access, typically 12 or 24 fibers per tray.

• Pressure Valve: Equipped with an air valve for sealing test or pressure monitoring.

2. Applications

• FTTH (Fiber to the Home)

• FTTB/FTTC/FTTX networks

• Backbone and access networks

• Aerial, manhole, duct, or direct burial installations

3. Advantages

• IP68-rated waterproof and dustproof protection

• Strong resistance to environmental factors like UV, moisture, and temperature shifts

• Easy installation and re-entry without special tools

• Compatible with ribbon or single fiber splices

• High mechanical strength and corrosion resistance

• Reusable closure body with replaceable sealing components

4. FAQs

Q1: What’s the difference between dome and horizontal closures?
A: Dome closures are vertically oriented, often used in aerial or buried setups. Horizontal closures are typically used in wall-mount or inline underground settings.

Q2: Can the closure support mid-span cable access?
A: Yes, many dome closures allow for mid-span access (express fiber management) without cutting all fibers.

Q3: How many fibers can this closure support?
A: It varies by model — from 12 cores up to 288 cores or more. Let us know your project requirement for the best fit.

Q4: Are they reusable?
A: Yes, dome closures are designed to be re-entered and reused, which helps reduce long-term maintenance costs.

Q5: Do you provide accessories like splice trays and cable ties?
A: Yes, each unit comes with standard accessories: splice trays, seals, cable clamps, heat-shrink tubing (if needed), and mounting kits.
