According to reports, AquanTIa, Cisco, Freescale and Xilinx have formed an NBASE-T alliance, and the companies are working on 2.5G/s and 5G/s Ethernet specifications to provide more practical standards for enterprises. . Chris Spain, vice president of product management at Cisco, pointed out that the next-generation wireless communication LAN standard Wave2 802.11ac network theoretical transmission rate will reach 6.9G / s, the 1G / s speed between the access point and the switch is obviously insufficient. The main goal of Cisco this time is to increase the transmission rate without being limited by the wiring structure. The NBASE-T Alliance will include 2.5G/s and 5G/s rates and POE technology in the Super Cat5e and Cat6 cable infrastructure, which extends cable life and avoids running between switches and access points. Core cable. But this is independent of the 25G Ethernet road alliance of Arista, Broadcom, Google, Microsoft and Mellanox. After the cooperation between Ethernet PHY device expert AquanTIa and Cisco, the best provider of network equipment, this may cause large fluctuations in the NBASE-T alliance. Cisco's VN tag fabric extension technology has evolved into 802.1BR, and if Cisco decides to use AquanTIa-based products, they will dominate the market. At present, the enterprise market needs IEEE standardization, and Broadcom is convening its peers to discuss IEEE 2.5G and 5G standards in November. Because the IEEE standard process takes about two years, Cisco and its partners may face technical challenges. On the other hand, AquanTIa has demonstrated that today's silicon can support 2.5 and 5G transmission rates with weak changes. The ultimate goal of the Ethernet Alliance and IEEE seems to be the same, but this potentially has some incompatibility issues. The upgrade of Ethernet may trigger a competition between standards and alliances, similar to the standard battle for wireless charging. The dominant Ethernet Alliance may also intervene to improve device interoperability in the future, waiting for IEEE standards to only delay market acceptance, while Cisco has the ability to lead the industry. NBASE-T Alliance advocates have also demonstrated their technical propositions for new wireless transmissions, which may introduce industry standards before the IEEE, which addresses a range of incompatibilities that may arise. According to reliable sources, the NBASE-T Alliance is still recruiting new members. Product application:
