Active Optical Cable (AOC) is a cabling technology that accepts same electrical inputs as a traditional copper cable, but uses optical fiber “between the connectors”. AOC uses electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces.
Active optical cable is composed of integrated optoelectronic devices and is used for high-speed, high-reliability interconnected transmission equipment between data centers, high-performance computers, large-capacity memories, and other equipment. It usually meets industrial standard electrical interfaces. The conversion of electricity to light to electricity uses the superiority of optical cables for data transmission. In simple terms, the active optical cable can be regarded as a system consisting of two optical transceivers and optical cable jumpers, but this system has a higher system rate and better reliability than an independent device.
The following list presents the major benefits of Active Optical Cable assemblies.
Longer Reach and Higher Bandwidth
Secure, Reliable Transport
Limited EMI/RFI Exposure
Low Bit-Error Rate (BER) – 10-15
Smaller Size and Lower Weight Compared to Copper Cables
Supports 4K UHD resolutions at 60Hz
HDMI Active Optical Cable (AOC) uses fiber optic technology to transport the digital HDMI signal. This means that the signal can be carried much further than with a traditional copper cable (up to 100 m), and reduces the risk of EMI/RFI interference. HDMI AOC cables also have dedicated copper power wires inside, so no external power supply is required.
