Active Optical Cable (AOC) is a cabling technology that accepts same electrical inputs as a traditional copper cable, but uses optical fibre “between the connectors”. AOC uses electrical-
An active optical cable (AOC) assembly is composed of 4 functional parts.
1. The Connector or Plug
2. An Active Optical Transceiver. Normally embedded inside the connector or plug.
3. An Optical connector. This connector is permanently attached to the shell and fibre. This permanent attachment shields the optical interface from the end user and also from environmental contaminants.
4. The Optical Fibre Cable
So the basic idea of AOC is to embed the active optical transceiver components into the electronic connector instead of using separate optical transceiver and plug-
WHO INVENTED AOC, AND WHY?
Simply put, Active Optical Cable (AOC) assemblies were invented to replace copper technology in data centres and high performance computing (HPC) applications.
The first driver came from InfiniBand technology. As InfiniBand data rates rise and data centre clusters grow in size, copper cable technology is getting stretched to its limits. InfiniBand Double Data Rate (DDR) of 20 Gigabits per second (Gbps) means that conventional copper cable is limited to an 8 to 10 meter reach.
This may be fine for small clusters, but for larger clusters, this physical link distance makes the physical layout of the cluster becomes a real challenge. Due to the inherent bandwidth-
Copper cable is heavy and bulky, making it difficult to physically manage the data centre. And because of the nature of electrical signals, electromagnetic interference (EMI) limits copper’s performance and reliability. If you have a scaled-
So that was why Intel and Luxtera invented Active Optical Cable assemblies to fill the gap.
Active Optical Cable assembly has many potential advantages. If the network equipment is properly designed, it becomes possible to have a common electrical port that can accept either passive copper cable or active copper cable, allowing the user to select the appropriate technology and cost with easy reconfiguration.
The optical connector can be an expensive, precision element (particularly for parallel optical links) due to tight manufacturing tolerances. This is eliminated by permanently attaching the fibres to the optics.
The following list presents the major benefits of Active Optical Cable assemblies.
