AQS-109 SFP+ Module

The Aquantia AQS-109 SFP+ module offers 2.5GBASE-T connectivity option for a system that has a built-in SFP+ port and lacks an integrated high-speed copper port. This module is based on Aquantia’s GEN2 AQrate® PHY which is a low-power, high performance device that support 3 speeds – 2.5GBASE-T/ 1000BASE-T/ 100BASE-TX. The SFP+ module delivers 2.5 GbE network connectivity speeds through 100 meters of Cat 5e and Cat 6 cabling. Legacy 1GbE and 100MbE links are also supported.

The Aquantia SFP+ modules are compliant with the NBASE-T Alliance PHY Specifications and the IEEE® 802.3an/802.3bz standards to implement 10GBASE-T/5GBASE-T/ 2.5GBASE-T/1000BASE-T/100BASE-TX transmission over twisted pair cabling. The Aquantia SFP+ modules operate over the Commercial 0° C to 70° C temperature range.

Data center solutions drive down costs & complexity

In the data center market users typically deploy direct-attach 10GB cables for servers to switch connections. Based on distance requirements, users must select either passive, active twinax or fiber optic connections, which are cost prohibitive. The new power-optimized twisted-pair copper solution allows the use of more powerful 10GBase-T SFP+ to deliver the best combination of performance, reach, and cost for all applications up to 30 meters.


In enterprise configurations, switches are typically shipping with 1G ports and 10G fiber-optic uplink slots to connect multiple switches together. Now, these uplinks can be achieved at higher speeds using the same slots but with cost-effective copper cabling.  

Aquantia’s technology is simple enough to be easily adapted to carrier markets, including the traditional Ethernet Passive Optical Network (EPON) and similar configurations. As performance demands increase, the pressure to either improve an existing network or convert to a more expensive configuration, and perhaps take on additional conversion and encapsulation requirements, also increases. Aquantia’s solution satisfies these performance demands without significant additional cost or complexity.

“We estimate that there is currently an installed base of at least twelve million data center-class SFP+ empty cages available for future provisioning as networking traffic demand increases,” said Seamus Crehan, president of Crehan Research. “Aquantia’s offering of the three speeds, 2.5, 5 and 10GBASE-T allows IT managers and data center providers to provision these empty slots with cost and power-efficient solutions based on the well-known and large base of twisted-pair copper cabling.”
