Essential Features and Specifications of Dome Fiber Optic Splice Closures

Comprehensive Guide to Dome Fiber Optic Splice Closures

IntroductionDome fiber optic splice closures, also known as vertical fiber optic splice closures, are critical components used in various fiber optic networks. These closures provide essential protection and splicing capabilities for outdoor fiber connections. They come in different sealing types, such as shrinkable and mechanical, and are designed to be versatile for different mounting environments, including aerial, underground, manhole, and pole.

Features and BenefitsDome fiber optic splice closures are designed with several key features that make them highly effective for managing and protecting fiber optic cables:

• Base and Dome Sealing: The base and dome are sealed with a clamp and O-ring system, ensuring a secure fit and easy fiber management.

• Sealing Types: The closures feature both mechanical and heat-shrinkable seals for ease of installation and reentry. No additional sealing adhesive tape is required.

• Durability: The design is compact, waterproof, UV-resistant, and capable of withstanding harsh environmental conditions.

• Compatibility: They are compatible with various cable types, including single fiber, ribbon, loose tube, central core, slotted core, and modular constructions.

• Versatility: Suitable for various deployment environments and applications, including aerial, buried, hand hole, manhole, tap-off, expressed, branch, and repair.

• Ease of Use: The closures can be opened and reused without special tools, making maintenance straightforward.

• Corrosion Resistance: All metallic parts are made of non-corrosive steel to ensure longevity.
