10GbE SFP+ PCIe Card

Mac / PC / PCIe
10 Gigabit Wired Networking
Ultra-Fast 10 Gb/s Network Connection
With increasing demands for greater data transfer speeds and more bandwidth over shared networks, and with specialized applications such as HD video editing using high-performance shared storage systems, it's no wonder that 10 Gigabit Ethernet (10GbE) use has skyrocketed—this high-speed wired networking standard offers ten times the performance of Gigabit Ethernet, the common wired network connection included with most computers today. Sonnet offers a powerfully simple way to add dual-port 10GbE connectivity to your Mac Pro® tower or Windows® PC—the Presto™ 10GbE SFP+.
Simple Set-Up. High-Performance Computing.
The Presto 10GbE SFP+ dual-port 10 Gigabit Ethernet PCI Express 2.0 adapter card enables you to connect your computer to high-speed infrastructure and storage without stepping down in speed. Setup is simple—after installing the low-profile card into an available x8 or x16 PCIe slot in your computer, just download and install a driver, connect to the switch or device's 10GbE port via LC fiber optic cables (SFP+ transceivers and fiber cables sold separately), or copper cables (sold separately), and then configure the card through the OS X® Network control panel or Windows Device Manager. This Sonnet solution is perfect for high-performance computing where low latency, high bandwidth, and low CPU overhead are required.

Its increased throughput performance and low host-CPU utilization are achieved through functions such as support for flow control, 64-bit address support for systems using more than 4GB of physical memory; and stateless offloads such as TCP, UDP and IPv4 checksum off2loading, enabling your computer to perform better while large files transfers or high I/O operations take place. With its dual ports, this Sonnet adapter supports transparent failover to keep your computer connected in case a single cable is disconnected or one of the ports fails, and it also supports link aggregation for increased throughput!
Flexibility of Short-Range or Long-Range SFP+ Transceivers
Sonnet offers two SFP+ transceiver options (sold separately), a short-range module (up to 300 meters, part number G10E-SFP-SR), and a long-range module (up to 10 kilometers, part number G10E-SFP-LR) that connect the Presto card via LC fiber optical cables (sold separately) to a network switch or storage. Alternatively, you can use cost-effective direct-attached SFP+-terminated copper cables up to 10 meters long (sold separately).
Optimized for Thunderbolt
Got a Thunderbolt connection, but no PCIe slot? Presto 10GbE SFP+ is ideal for use in Thunderbolt-to-PCIe card expansion systems — the combo enables you to add ultra-fast 10GbE network connections to any Mac or Windows PC with a Thunderbolt 2 port.

  1. Connection requires SFP+ transceiver modules (with LC fiber optical cables; sold separately), or SFP+-terminated "Direct Attach" twinax copper cable (sold separately).
  2. Creating Intel ANS teams and VLANs on Windows 10 is currently not supported. As a result, when created, teams and VLANs do not pass traffic. Sonnet expects that ANS will be supported on Windows 10 client in a future release.
