OPEN聯(lián)盟是One-Pair Ether-Net Alliance SIG的縮寫，即單對以太網(wǎng)聯(lián)盟。2011年11月成立，博通公司（Broadcom Corporation；NASDAQ: BRCM）與恩智浦半導(dǎo)體（NXP Semiconductors N.V.；NASDAQ: NXPI）、飛思卡爾半導(dǎo)體公司（Freescale Semiconductor；NYSE: FSL）以及Harman International（NYSE:HAR）聯(lián)合，成立了OPEN聯(lián)盟（OPEN Alliance），BMW與Hyundai兩家汽車業(yè)者也是創(chuàng)始成員。OPEN聯(lián)盟計劃在未來的幾個月納入其他汽車供應(yīng)商與制造商。
OPEN Alliance SIG的成立目的主要，是鼓勵業(yè)界將100Mbps以太網(wǎng)鏈接技術(shù)作為標(biāo)準(zhǔn)的汽車連接技術(shù)，并大規(guī)模普及應(yīng)用。聯(lián)盟將致力于滿足業(yè)界對車輛安全、舒適與娛樂信息的需求，同時大幅降低網(wǎng)路復(fù)雜性與纜線成本。
創(chuàng)辦成員初期的發(fā)展重點面向：建立兼容性要求、第三方測試、認(rèn)證程序以及高數(shù)據(jù)傳輸速率規(guī)格要求，所有有興趣的OPEN聯(lián)盟成員都可以在合理，而且沒有差別待遇的條件（RAND terms）下，通過Broadcom的授權(quán)使用BroadR-Reach規(guī)格。
對于新成立的SIG組織，成功的關(guān)鍵在于將Broadcom公司的BroadR-ReachR技術(shù)作為開放性標(biāo)準(zhǔn)。BroadR-Reach技術(shù)是專門為滿足汽車業(yè)者的嚴(yán)格要求而開發(fā)的，可通過非遮蔽的單對雙絞電纜線提供100Mbps的高效能帶寬。由于不需要昂貴且體積龐大的屏蔽布線，汽車制造商可以大幅降低連接成本與布線重量。

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.
