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