In professional audiovisual, industrial control, and specialized security surveillance applications, DVI (Digital Visual Interface) remains a vital standard for connecting computers to high-definition displays and large screens due to its stable digital signal transmission and broad device compatibility. However, traditional copper DVI cables face severe distance limitations when transmitting high-definition signals: beyond 5-10 meters, signal quality begins to degrade, resulting in blurred images, ghosting, or even black screens. Additionally, remote displays or signal repeaters typically require independent power supplies, increasing wiring complexity and potential failure points.
The DVI optical-electrical composite cable innovatively integrates fiber-optic transmission with copper power delivery. It transmits lossless video signals via fiber to overcome distance limitations while utilizing built-in copper conductors to provide stable power to remote devices. Karobert Technology precisely addresses system integration needs by launching a high-performance DVI optical-electrical composite cable series. This series delivers an all-in-one solution featuring ultra-long-distance transmission, pristine image quality, and simplified cabling, serving as a reliable and efficient connection link for professional projects.
Karobert Solution: Intelligent Integration of "Optical Fiber for Video, Copper Wire for Power"
Our optical-electrical composite cables employ a physical structure where "the fiber core transmits light while the jacket supplies power," integrating multiple functions within a single cable.
High-Performance Optical-Electrical Conversion: Integrated micro optical-electrical conversion modules at both ends. The transmitter converts DVI digital electrical signals into optical signals, while the receiver reconverts them back to electrical signals. The entire process is protocol-transparent and plug-and-play.
Ultra-Long Transmission Distance: Supports transmission distances of 30m, 50m, 100m, or even further. Image quality remains identical to a 1m direct connection-no attenuation, ghosting, or blurring.
Absolute Electromagnetic Interference Resistance: Fiber optic transmission is completely unaffected by electromagnetic interference. It guarantees absolutely stable and pure images even near high-voltage rooms, radio stations, or large motors.
Integrated Power Supply: The cable incorporates one or more low-voltage DC power conductors (e.g., 18AWG), enabling direct power delivery to receiving devices such as DVI-input monitors requiring 5V/12V power or signal extender modules.
Simplified Cabling: Achieves "single-cable connectivity," requiring only one cable to simultaneously transmit video signals and power. This greatly simplifies system design and installation while reducing overall costs.
Safe and Reliable: Power lines and signal fibers are structurally isolated, preventing interference and ensuring stable power delivery.
Industrial-grade connectors: DVI interfaces (typically DVI-D 24+1 or DVI-I 29+1) feature metal housings for enhanced shielding and robust mating strength.
Durable outer jacket: Constructed from high-density, abrasion-resistant PVC or flame-retardant materials, it protects internal fibers and conductors, making it suitable for conduit installations, wall embedments, and other engineering environments.
Clear labeling: Cables typically feature distinct markings indicating signal direction (Source to Display) and power specifications.
