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.
AOC cables were created as an alternative to conventional Direct Attach Copper (DAC) cables to offer increased distance. They are primarily deployed in data centres and High-Performance Computing (HPC) applications where the combination of distance and value is required. More and more businesses are relying on both high-performance computing and interconnected storage solutions, meaning that Active Optical Cables are primed to become much more common in the years to come, making their copper predecessors obsolete.
The proliferation of bandwidth-hungry applications such as 4K/8K/10K video, as well as augmented and virtual reality, are all fuelling the need for reliable, faster data transmission between sources and displays. At lengths of 5 m and beyond, copper cables are simply no longer able to keep up with this insatiable bandwidth demand at the speeds required. Fibre optics is the answer.
Active Optical Cables (AOCs) convert electrical signals into optical for the transmission of video and data communications, over short or long distances, between sources and displays. Compared with direct attach copper cable for video and/or data transmission, AOCs provide many advantages, such as lighter weight, faster speeds, lower power consumption, lower interconnection loss, and increased flexibility. Because AOCs are thin and flexible, they can be routed through walls much easier than a copper cable.
ADVANTAGES OVER COPPER WIRING
The advantages of optical fiber communication with respect to copper wire systems are:
A single optical fiber can carry over 3,000,000 full-duplex voice calls or 90,000 TV channels.
LOW ATTENUATION LOSS OVER LONG DISTANCES
Attenuation loss can be as low as 0.2 dB/km in optical fibre cables, allowing transmission over long distances without the need for repeaters.
Optical fibers do not conduct electricity, preventing problems with ground loops and conduction of lightning. Optical fibers can be strung on poles alongside high voltage power cables.
MATERIAL COST AND THEFT PREVENTION
Conventional cable systems use large amounts of copper. Global copper prices experienced a boom in the 2000s, and copper has been a target of metal theft.
SECURITY OF INFORMATION PASSED DOWN THE CABLE
Copper can be tapped with very little chance of detection.
Optical fibres can be used as sensors to measure strain, temperature, pressure and other quantities by modifying a fiber so that the property to measure modulates the intensity, phase, polarization, wavelength, or transit time of light in the fibre.
Fiber optic sensors are used as advanced intrusion detection security systems. The light is transmitted along a fiber optic sensor cable placed in a pipeline and the returned signal is monitored and analyzed for disturbances. This return signal is digitally processed to detect disturbances and trip an alarm if an intrusion has occurred this happens 24/7 and instantly with pinpoint accuracy.
When using AOCs, it is important to make sure that the source end of the cable is connected to the device that generates the video signal.
