OPEN联盟是One-Pair Ether-Net Alliance SIG的缩写，即单对以太网联盟。2011年11月成立，博通公司（Broadcom Corporation；NASDAQ: BRCM）与恩智浦半导体（NXP Semiconductors N.V.；NASDAQ: NXPI）、飞思卡尔半导体公司（Freescale Semiconductor；NYSE: FSL）以及Harman International（NYSE:HAR）联合，成立了OPEN联盟（OPEN Alliance），BMW与Hyundai两家汽车业者也是创始成员。OPEN联盟计划在未来的几个月纳入其他汽车供应商与制造商。
OPEN Alliance SIG的成立目的主要，是鼓励业界将100Mbps以太网链接技术作为标准的汽车连接技术，并大规模普及应用。联盟将致力于满足业界对车辆安全、舒适与娱乐信息的需求，同时大幅降低网路复杂性与缆线成本。
创办成员初期的发展重点面向：建立兼容性要求、第三方测试、认证程序以及高数据传输速率规格要求，所有有兴趣的OPEN联盟成员都可以在合理，而且没有差别待遇的条件（RAND terms）下，通过Broadcom的授权使用BroadR-Reach规格。
对于新成立的SIG组织，成功的关键在于将Broadcom公司的BroadR-ReachR技术作为开放性标准。BroadR-Reach技术是专门为满足汽车业者的严格要求而开发的，可通过非遮蔽的单对双绞电缆线提供100Mbps的高效能带宽。由于不需要昂贵且体积庞大的屏蔽布线，汽车制造商可以大幅降低连接成本与布线重量。

ABOUT OPEN ALLIANCE SIG
OPEN Alliance is designed to encourage wide scale adoption of Ethernet-based, single pair unshielded networks as the standard in automotive applications. The jointly developed OPEN Alliance SIG will address industry requirements for improving in-vehicle safety, comfort, and infotainment, while significantly reducing network complexity and cabling costs.
Interest in one pair Ethernet technology has grown dramatically as the automotive industry accelerates its adoption of Ethernet based networks delivering both high-performance bandwidth and the industry's lowest cost cabling solution for Ethernet connectivity over a single pair, unshielded twisted cable. The technology is engineered to meet the stringent in-vehicle requirements of the automotive industry and optimized for multiple in-car applications.
Instrumental in the proliferation of the technology is the establishment of an open standard special interest group. Founding members will initially focus on establishing interoperability requirements, third party testing, certification procedures, and higher data rate specification requirements. The OPEN Alliance plans to expand its membership roster in the coming months to additional automotive suppliers and manufacturers.
