OPEN Alliance Inc.

The OPEN Alliance (One-Pair Ether-Net) Inc. is a non-profit, open industry alliance of mainly automotive industry and technology providers collaborating to encourage wide scale adoption of Ethernet-based networks as the standard in automotive networking applications. http://www.opensig.org/Automotive-Ethernet-Specifications/ The Technology Interest in one pair Ethernet technology has grown dramatically as the automotive industry accelerates adoption of Ethernet-based networks. Early adoption of the BroadR-Reach™ Ethernet technology enabled multiple in-vehicle systems (such as infotainment, automated driver assistance and on board-diagnostics) to demonstrate simultaneous access to information over a single unshielded twisted pair cable. The completion of the IEEE automotive Ethernet standards (100BASE-T1,1000BASE-T1 and 1000BASE-RH) built upon that early adoption effort and established automotive Ethernet internationally. Moving from shared medium bus topologies to a switched Ethernet network provides flexibility and freedom in the implementation of the in-vehicle EE architecture and connectivity to the outside world. Automotive qualified Ethernet technology is engineered to meet the stringent in-vehicle requirements of the automotive industry. Automotive Ethernet Technology Open Alliance Technology As consumer demand for in-vehicle connectivity and advanced driver assistance (ADAS) continues to grow, the automotive industry is under constant pressure to deliver competitive, innovative features while minimizing cost. Automotive Ethernet technology allows multiple in-vehicle systems to simultaneously access information over a single unshielded twisted pair cable. By eliminating cumbersome, shielded cabling, automotive manufacturers can significantly reduce connectivity costs and cabling weight.
