Bridgee’s proprietary modular connector structure for its MPO pure optical fiber pre-installed cable has officially been granted a Chinese Utility Model Patent.

Patent No.: ZL 202521966541.X
Publication of Grant No.: CN224457071 U

Traditional all-in-one optical fiber HDMI pre-installed cables can create a number of installation challenges: oversized connectors at both ends can become stuck in conduits, incorrect cable orientation can result in an entire cable being rendered unusable, and connector damage or equipment upgrades may require the entire embedded cable to be replaced — sometimes even requiring walls to be opened again.

Bridgee’s patented modular architecture addresses these challenges throughout the entire lifecycle, from installation and everyday use to future system upgrades.

1. Patented Modular Connection｜Replaceable Connectors, Flexible Interfaces

The cable features a tool-free push-lock, plug-and-play connection structure, allowing the optical fiber cable and signal connectors to be connected or detached without specialized tools.

1. Replaceable Signal Connectors

If a connector becomes damaged, worn, or faulty, the HDMI, DP, or USB connector can be replaced independently while the optical fiber installed inside the wall remains intact. There is no need to remove the conduit or open the wall.

2. Flexible Interface Options
The current system supports interchangeable HDMI, DP, and USB signal connectors. A single pre-installed optical fiber cable can therefore support a variety of applications, including projectors, desktop computers, large-format displays, and industrial control equipment.

3. Designed for Future Expansion
The modular architecture provides room for further interface development. Additional connector specifications can be introduced in the future to accommodate evolving AV and data transmission requirements.

2. Ultra-Slim Cable｜Easy Installation Through Narrow Conduits

During pre-installation, only the 3 mm ultra-slim optical fiber cable needs to be routed through the conduit.

Without bulky optical-electrical conversion modules attached to both ends, the cable can pass more easily through narrow cable channels and conduits with multiple bends, significantly reducing installation resistance and the risk of rework.

The MPO optical path also features a polarity-independent design, eliminating the need to distinguish between input and output ends during installation and reducing the risk of incorrect routing.

3. Two Protection Versions｜Durable, Flame-Retardant Low-Smoke Zero-Halogen Construction

Bridgee offers two versions to accommodate different installation environments:

✅ Standard Version
Provides basic tensile and protective performance for conventional residential in-wall installations.

✅ 304 Stainless Steel Armored Version
Features an additional 304 stainless steel protective layer for enhanced compression resistance, rodent protection, and bending durability, making it suitable for demanding applications such as suspended ceilings, concealed floor installations, and outdoor cabling.

Both versions use low-smoke zero-halogen (LSZH) outer materials, offering excellent flame-retardant performance and long-term durability for concealed installations.

4. Core Transmission Configuration｜12-Core OM3 Multimode Fiber for Low-Loss Long-Distance Transmission

The cable incorporates 12-core OM3 multimode optical fiber for pure optical signal transmission.

By using optical transmission, the system is less susceptible to electromagnetic interference from household electrical wiring and AV equipment, helping reduce issues such as electrical noise and image flickering.

The system supports stable transmission over distances of up to 100 meters and supports HDMI 2.1 56Gbps bandwidth, with native support for high-performance applications including 8K@60Hz and 4K@144Hz.

5. Application Scenarios

With 100% pure optical fiber transmission and strong resistance to electromagnetic interference, Bridgee MPO is designed for applications requiring a high degree of electrical isolation and reliable long-distance transmission.

It is suitable for a wide range of demanding environments, including:

• Live streaming and broadcast

• Esports and gaming systems

• Home theaters

• Airports and railway stations

• Conference centers and exhibition venues

• Medical equipment

• Professional AV and engineering applications

Conclusion

Powered by its proprietary patented modular architecture, the Bridgee MPO pure optical fiber cable addresses many of the limitations associated with traditional pre-installed cables.

By combining installation convenience, long-term reliability, and upgrade flexibility, together with professional structural engineering and high-performance optical transmission technology, Bridgee MPO provides a future-ready connectivity solution for demanding AV and engineering installations.
