Fiber Optic Closures | 光纤闭合器

Our fiber optic closures provide secure protection and organized management for fiber optic splice points in a wide range of network environments. Designed for outdoor and indoor applications, these closures ensure durable and weather‑resistant performance for FTTH, telecom, cable broadband, and municipal network infrastructure.

Splice Closures for Outdoor Networks

Outdoor splice closures are engineered to protect fiber splices from moisture, dust, UV exposure, and mechanical stress. With high ingress protection (IP65~IP68), they are suitable for aerial, underground, and pedestal installations in harsh environments.

Indoor Fiber Closures & Enclosures

Indoor fiber closures offer compact, secure housings for splice points within equipment rooms, data centers, and residential or commercial buildings. These enclosures support structured cabling systems and facilitate efficient fiber routing and maintenance.

Types of Fiber Optic Closures

We provide a range of closure types including dome closures, inline closures, horizontal closures, and high‑capacity splice trays to meet project requirements from small residential networks to large telecom backbones.

Key Features

• Weatherproof and dustproof housing for outdoor use
• High‑capacity splice trays for fiber management
• Secure cable entry and sealing for aerial and underground cables
• Modular design supporting diverse fiber counts
• Easy installation and maintenance access

Applications

• FTTH access and distribution networks
• Telecom and broadband backbone infrastructure
• Aerial, duct, and underground fiber installations
• Enterprise and campus fiber network systems
• Data center fiber termination and protection

All our fiber optic closures are manufactured to strict quality standards and can be customized for fiber count, environment protection level, closure type, and mounting style. Whether for large‑scale telecom projects or localized FTTH access deployments, our closures provide reliable protection and efficient fiber management for network operators and installers.
