EnterpriseAQRATE AQR405

Aquantia’s 28nm AQrate® AQR405 is the world’s only quad-port five-speed 10GBASE-T/5G/2.5G/1000BASE-T/100BASE-TX PHY in the industry.

The Aquantia 28nm AQrate PHY generation enables Enterprise Networking to evolve beyond 1G to 5G and 2.5G data rates through existing Cat5e and Cat6 cabling infrastructure. AQrate delivers 5G and 2.5G network connectivity speed through 100m of Cat5e or Cat6 cabling facilitating the unabated roll-out of 802.11ac WLAN infrastructure with zero change to legacy cabling. AQR405 integrates such features as Energy Efficient Ethernet (EEE), 1588v2, MACsec and supports all PoE standards up to 60W.

In a 25mm package, the AQR405 provides a small footprint quad-port solution ideal for high-density systems, such as 48-port Enterprise and Campus switches. In this 25mm package, the AQR405 also provides backward compatibility with the AQ1402 40nm as well as the AQ2402 28nm Quads.
