Coaxial cables have long been used for data network connections. Containing an insulated wire at its center surrounded by a shield of conductive material, coaxial cables were originally used for Ethernet and are still widely used today for cable television connections. Different types of coaxial cables have different levels of performance, and automotive applications also use specific cables based on parameters.
The robustness and noise immunity of coaxial cables make them popular in automotive applications. For more than 20 years, most automotive OEMs have adopted a global interface standard called FAKRA (Fachkreis Automobil). These connectors perform well at frequencies up to 3 GHz and can also be adapted for applications at 6GHz with speeds up to 8Gbit/s through specific design features of the contacts.
The latest automotive coax applications include digital camera systems in vehicles. Taking advantage of the high bandwidth capabilities of coaxial cables, video signals and camera power can be transmitted over a single cable.
As applications scale from simple backup cameras to complex surround-view vision systems, the FAKRA interface has grown in size. A new generation of smaller-sized coaxial cable connectors is being developed to address space issues in vehicles.
These "mini-coax" connectors are much smaller than current interfaces, allowing for increased connector density on the end of devices of the same size. In the automotive industry, there are two types of micro-coax defining the interface, and Aptiv is developing solutions that can support both. In addition, Aptiv is actively involved in the development of International Organization for Standardization (ISO) and United States Council of Automotive Research (USCAR) standards, ensuring our products are suitable for any global application.
Another feature of micro-coax systems is that they support bandwidths far beyond current automotive products. While FAKRA can support frequencies up to 6GHz, micro coaxial cables can support applications from 9 GHz to 15GHz, which means that the bandwidth can reach more than 20Gbit/s.
Future automotive computing systems will include numerous coaxial cables for transferring data between more complex on-board computing platforms.
