Outdoor Optical Cross-Connect Cabinet (OCC)
The Outdoor Optical Cross-Connect Cabinet (OCC) is designed for fiber connection, distribution, splicing, and management in outdoor FTTx and access networks. It is typically installed between the feeder cable and distribution cable, serving as an important access-layer node for outdoor fiber networks.
The OCC provides multiple functions in one enclosure, including fiber splicing, termination, storage, distribution, splitting, and cable routing. By integrating these functions, the cabinet reduces the need for additional patching components and helps simplify the fiber network structure.
The cabinet provides a direct interface between trunk and distribution cables. Its organized fiber routing system makes installation, operation, and maintenance easier. It also supports future network expansion and upgrades while helping reduce connection points, potential failure points, and overall deployment costs.
Designed for demanding outdoor environments, the cabinet provides reliable protection against water, moisture, corrosion, impact, and sudden climate changes. The capacity can be customized from 72 to 576 fibers according to different network requirements.
Key Features
High-Density Fiber Capacity
The cabinet supports a flexible capacity from 72 to 576 fibers. The configuration can be customized according to network size and deployment requirements.
Feeder-to-Distribution Connection
The OCC provides a centralized connection point between feeder cables and distribution cables. It supports fiber splicing, termination, storage, and cross-connection within one cabinet.
Integrated Fiber Management
The internal fiber routing system provides clear and organized fiber paths. This design makes fiber identification, maintenance, and network upgrades more convenient.
Direct Splicing Function
The built-in direct splice unit supports direct fiber connection without requiring additional distribution components. This helps simplify the network structure and reduce unnecessary connection points.
Outdoor Environmental Protection
The cabinet provides reliable protection against water, moisture, corrosion, and mechanical impact. It can withstand sudden climate changes and demanding outdoor operating conditions.
Flexible Network Configuration
The cabinet can support different combinations of splicing, termination, storage, splitting, and distribution modules. This allows operators to configure the OCC according to specific FTTx network requirements.
Secure Fiber Protection
Reliable cable fastening, fiber management, and grounding devices help protect optical fibers and maintain stable network operation.
Ribbon and Non-Ribbon Fiber Support
The internal structure is compatible with both ribbon and non-ribbon fiber optic cables, providing greater flexibility for different network architectures.
Quick Installation
The modular internal design simplifies installation and commissioning. Technicians can efficiently complete fiber splicing, routing, and cable management inside the cabinet.
Secure Door Design
The cabinet features a specially designed door locking mechanism that provides reliable physical protection and helps prevent unauthorized access or damage.

Benefits for FTTx Networks
The Outdoor Optical Cross-Connect Cabinet (OCC) integrates multiple fiber management functions into a single outdoor enclosure. It reduces the number of adapters, patch cords, and unnecessary connection points in the network.
As a result, operators can achieve lower optical loss, fewer potential failure points, easier fiber management, and simpler network upgrades. The modular capacity from 72 to 576 fibers also allows the cabinet to adapt to different network scales and future expansion requirements.
The OCC provides a practical and scalable solution for high-capacity outdoor fiber distribution and access network deployment.
