OYI’s Optical Fiber Closure Solution: Empowering Seamless Connectivity Worldwide

In the digital era, where uninterrupted data transmission is the backbone of global communication, a reliable optical fiber infrastructure is non-negotiable. At the heart of this infrastructure lies the optical fiber closure solution—a critical component that safeguards fiber connections, ensures signal integrity, and adapts to diverse environments. OYI International., Ltd., a Shenzhen-based innovator with 17 years of expertise, delivers industry-leading optical fiber closure solutions designed to address the most demanding connectivity challenges across telecom, data centers, cable TV, and industrial sectors.

Product Overview: Engineering Excellence in Every Detail

OYI’s optical fiber closure solution centers on the Fiber Closure Box (also known as Optical Splice Box or Joint Closure Box), a versatile enclosure engineered to protect fiber splices and connections from harsh external factors. Available in multiple types—including dome-shaped, rectangular, and inline designs—the solution caters to both aerial, underground, and direct-burial installations.

Design & Materials: Crafted from high-grade UV-resistant PC/ABS composites and reinforced with aluminum alloy hinges, the closure boasts exceptional durability. Its IP68-rated sealing ensures resistance to water, dust, and corrosion, making it ideal for outdoor use alongside Outdoor Cable Tube and Outdoor Ftth Drop Cable.

Technical Specifications: With capacities ranging from 12 to 288 fibers, it supports both fusion and mechanical splicing, accommodating PLC Splitter Box integration for efficient signal distribution. The closure’s mechanical strength—withstanding up to 3000N axial pull and 1000N impact—guarantees long-term performance even in rugged conditions.

Solv ing Core Challenges: How OYI’s Solution Delivers

Fiber networks face myriad challenges: environmental wear, signal loss, complex installations, and scalability limits. OYI’s closure solution addresses these head-on:

Protection: The airtight, waterproof seal prevents moisture ingress, a common cause of signal degradation, while its robust casing shields against rodents, extreme temperatures (-40°C to +85°C), and chemical exposure—critical for Conductor Opgw and outdoor telecom networks.

Efficiency: Pre-installed splice trays and modular design reduce on-site labor time by 40%, simplifying integration with Network Termination Box and Optical Distribution Box.

Scalability: Easily expandable to support additional fibers or Optical Switch Box upgrades, it adapts to growing network demands, from small FTTH deployments to large-scale data centers.

Installation & Usage: Simplified for Every Scenario

Installing OYI’s Optical Fiber Splice Box is straightforward, requiring minimal tools:

1.Prepare the site: Ensure the mounting surface (pole, wall, or underground vault) is clean and stable.

2.Route cables: Feed Fiber Optic Cable Tube and Drop Cable through the closure’s entry ports, using cable glands to secure them.

3.Splice fibers: Place stripped fibers into the splice tray, perform fusion splicing, and organize excess fiber using built-in management clips.

4.Seal and secure: Close the closure, tighten the locking latches, and verify the seal with a pressure test—compatible with Terminal Box Fiber Optic and Ftth Distribution Box.

Applications & Complementary Products

OYI’s closure solution integrates seamlessly with a range of products to form end-to-end systems:

FTTH Networks: Pair with Outdoor Ftth Drop Cable, Plc Splitter Box, and Ftth Fiber Optic components for last-mile connectivity.

Telecom Backbones: Combine with Conductor Opgw and Fiber Optic Converter Box for high-capacity long-haul links.

Industrial Settings: Use with Fiber Patch Panel Box and Optical Switch Box to ensure reliable connections in factory automation.
