Dome Type Fiber Optic Splice Closure for Rugged Outdoor Splicing Applications

Overview

The dome-type fiber optic splice closure is a high-performance outdoor enclosure designed for secure and durable fiber splicing. Crafted from UV-resistant polypropylene with rugged mechanical sealing, it achieves an IP68 rating for full protection against dust and water. Capable of withstanding impacts, vibrations, chemical exposure, and harsh temperatures from –35 °C to +70 °C, it is appropriate for aerial, buried, wall, pole-mounted, or manhole applications.

Main Features

• Durable polypropylene dome shell provides unmatched environmental resistance and longevity.

• Modular splice tray design supports up to four trays, accommodating up to 96 fiber splices.

• Mechanical (gel-free) sealing enables easy re-entry and repeated use without compromising protection.

• Multiple cable ports—including six Ø18 mm and two Ø12 mm spares—offer flexible fiber entry and routing.

• Compact and robust structure designed for long-lasting reliability even in challenging outdoor conditions.
