Application Scenarios
-
Professional AV & Conference Systems: Delivering uncompressed, high-definition video from remote control rooms to ceiling-mounted projectors or auditorium displays over long distances without signal boosters.
-
Digital Signage & DOOH (Digital Out-Of-Home): Ensuring stable, zero-latency image transmission for large-scale commercial advertising screens and stadium displays where standard copper cables fail to reach.
-
Medical Imaging Equipment: Providing complete galvanic isolation (via fiber optics) and high-resolution video feeds between scanning rooms (MRI/CT) and diagnostic viewing stations, ensuring patient safety and EMI resistance.
-
Industrial Automation & Machine Vision: Acting as a robust, EMI-immune video link on factory floors, protecting high-definition video signals from heavy electromagnetic interference generated by large machinery.
Frequently Asked Questions
Are these AOC DVI cables directional?
Yes. Because they utilize built-in optoelectronic transceivers to convert electrical signals to optical signals and back, they must be connected directionally. The connectors are clearly labeled "Source" (for the PC/Player) and "Display" (for the Monitor/Projector).
Do I need an external power supply to run this cable over 50 meters?
No. Our DVI AOC assemblies are designed to draw operating power directly from the 5V pin (Pin 14) of the DVI source device. No external USB power or adapters are required for standard operations.
Can you customize the cable length and jacket material for specific environments?
Absolutely. As an OEM factory, we offer customized lengths up to 100 meters. We can also modify the outer jacket to Low-Smoke Zero-Halogen (LSZH) for building plenums or TPU for enhanced industrial durability.
Do your DVI AOC assemblies comply with global safety standards?
Yes, our active optical cables are fully compliant with CE, RoHS, and REACH directives, and the raw fiber/copper composite cables meet stringent UL flammability ratings.
What is the Minimum Order Quantity (MOQ) and lead time for custom AOC orders?
Due to the specialized active components, the MOQ for custom AOC assemblies is typically around 100 to 500 pieces, depending on the length and jacket requirements. Standard mass production lead times run between 3 to 4 weeks.
Overview and Application Notes
Overview Engineered to overcome the length limitations of traditional copper wires, our DVI-D 24+1 Active Optical Cable (AOC) Assemblies deliver uncompressed, high-resolution digital video signals over extensive distances with zero degradation. Utilizing advanced embedded optoelectronic transceivers and high-quality multimode optical fibers, these cables ensure flawless 2560×1600 or 1080p video transmission while offering absolute immunity to Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). Manufactured in our ISO-certified facility, these AOC assemblies are significantly thinner, lighter, and more flexible than standard DVI copper cables. As a factory-direct OEM/ODM partner, we provide tailored solutions including custom extreme lengths (up to 100 meters), specialized jacket materials (such as LSZH or TPU for harsh environments), and rigorous testing to guarantee plug-and-play reliability in your professional AV or industrial systems.
Application Notes
-
Directional Installation: AOC cables are strictly directional. Always ensure the connector labeled “Source” is connected to the PC or transmitter, and the connector labeled “Display” is connected to the monitor or projector.
-
Bend Radius Restrictions: Although flexible, the internal fiber optic strands are susceptible to micro-bending losses or breakage. Maintain a minimum bend radius of at least 20mm (or as specified on the datasheet) during routing and installation.
-
No External Power Required: The built-in active chips draw a minimal amount of operating power (typically <0.5W) directly from pin 14 of the DVI source port. Ensure the source device complies with standard DVI power output specifications.
-
Pulling Tension: Do not apply excessive pulling force directly on the connectors when routing through conduits. Use a pulling mesh or grip that distributes the load onto the cable jacket.
