What is a display port Active Optical Cable?
A DisplayPort Active Optical Cable (AOC) is a type of cable that combines DisplayPort technology with active optical fiber technology. It is designed to transmit high-definition video and audio signals over longer distances while maintaining signal integrity and quality.
DisplayPort AOCs utilize optical fibers for data transmission, allowing for extended reach compared to traditional copper DisplayPort cables. These cables incorporate active components, such as lasers and photodiodes, to convert electrical signals into optical signals and back to electrical signals at the receiving end.
Key features and benefits of DisplayPort AOCs include:
Extended Distance: DisplayPort AOCs can transmit DisplayPort signals over significantly longer distances than copper DisplayPort cables, often ranging from tens to hundreds of meters. This makes them suitable for applications where longer cable runs are required.
High Bandwidth: DisplayPort AOCs support high bandwidth and data transfer rates, enabling the transmission of high-definition video resolutions (such as 4K, 8K, or higher) along with audio signals.
Immunity to EMI/RFI Interference: Optical fibers used in DisplayPort AOCs are not susceptible to electromagnetic interference (EMI) or radio frequency interference (RFI), ensuring a clean and stable signal transmission.
Lightweight and Flexible: DisplayPort AOCs are typically thinner and lighter compared to traditional copper DisplayPort cables, making them easier to route and install in tight spaces.
Plug-and-Play: DisplayPort AOCs are usually designed as plug-and-play solutions, requiring no additional power adapters or signal boosters for operation.
DisplayPort AOCs are commonly used in various applications, including professional audio/video installations, digital signage, video walls, broadcast systems, and other scenarios where long-distance DisplayPort connections are needed.
When using a DisplayPort AOC, it is important to ensure compatibility with the DisplayPort version supported by the connected devices and to adhere to the cable's maximum supported distance.
Overall, DisplayPort AOCs provide a reliable and efficient solution for extending DisplayPort connections over longer distances while maintaining high-quality video and audio transmission.
