Sonnet G10E-SFP-2XA-E2 Overview

Add 10 Gb/s network speeds to your Mac, Windows PC, or Linux server, with the Presto 10GbE Dual SFP+ Slot x8 PCIe 2.0 Network Adapter Card from Sonnet. 10GbE is approximately 10x faster than standard Gigabit connections, saving you time in demanding high-bandwidth tasks, such as HD video editing, large file transfers, and more. This low-profile adapter plugs into your computer's available x8 or x16 PCIe 2.0 slot and requires (optional) SFP+ transceivers and cabling for operation. The Presto is compatible with several SFP+ transceivers:

  • Short-range multi-mode fiber optic (up to 984')
  • Long-range single-mode fiber optic (up to 6.2 miles)
  • 10GBASE-T copper CAT-6/CAT-6A Ethernet (up to 328')
  • Direct-attach Twinax copper cables (up to 33')


Transparent Fallover

If one of the two ports fail or a cable is removed, this feature is meant to ensure that your computer remains connected .

Optimized for Thunderbolt

If you have a Thunderbolt connection but no PCIe slot available, you can use the Presto with either the (optional) Sonnet Echo Express or xMac Thunderbolt-to-PCIe card expansion systems.

In order to determine whether the return is initiated due to a technical problem, we may ask for you to provide visual support like images or a video on the item(s).


Returned merchandise must be in its original packaging, and placed in a decent shipping box, e.g. the same box that we shipped the items to you in. Please make sure to clearly mark the RMA code you have received from us outside on the box.

Do not forget to cover or peel off any existing shipping labels on the box.

Customs, duties & taxes

There are no customs duties or taxes on orders shipping within the EU. Orders shipped outside of the EU may be subject to import taxes, customs duties and fees collected by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are collected once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid for by the recipient; we have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; and when customs clearance procedures are required, it can cause delays beyond our original delivery estimates. We advise that you contact your local customs office for more information.
