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. Operators can customize the configuration according to network size and deployment requirements. Furthermore, the terminal module features a horizontal draw-out structure with 12 cores per unit. Technicians can draw out each core separately, which greatly simplifies distribution operations and reduces fiber bending.
Feeder-to-Distribution Connection
The OCC creates a centralized connection point between feeder cables and distribution cables. Moreover, it seamlessly integrates fiber splicing, termination, storage, and cross-connection within a single cabinet.
Integrated Fiber Management
The internal fiber routing system provides clear and organized fiber paths. Therefore, managers can complete fiber identification, maintenance, and network upgrades more efficiently.
Direct Splicing Function
The built-in direct splice unit enables direct fiber connection without requiring additional distribution components. As a result, this feature simplifies the network structure and reduces unnecessary connection points.
Outdoor Environmental Protection
The robust cabinet structure provides superior protection against water, moisture, corrosion, and mechanical impact. In addition, it withstands sudden climate changes and demanding outdoor operating conditions.
Flexible Network Configuration
The cabinet easily accommodates different combinations of splicing, termination, storage, splitting, and distribution modules. Consequently, operators can flexibly configure the OCC for specific OSP construction supplies and FTTx network demands. Furthermore, the optical fiber splitter maintains a highly reasonable structure. Technicians can easily fix, ground, and operate the sheathed cable cores without removing the splitter.
Secure Fiber Protection
Reliable cable fastening mechanisms, fiber management structures, and grounding devices work together to protect optical fibers and maintain stable network operation. In addition, the horizontal wiring duct makes the overall cable layout neater and more logical.
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.
