Specifications	Bandwidth: 3.94 GB/s (x4 PCIe 3.0 ) Compatible Networks: 10 Gbps Full Duplex Support: Yes Jumbo Frame Support: 15K max. Maximum Data Transfer Rate Chassis: 40 Gbps (Thunderbolt 3) / PCIe Card: 20 Gbps - Full-Duplex Promiscuous Mode: Yes Supported Protocols: IEEE 802.3ad (Link Aggregation), IEEE 802.3x (2005 Flow Control Support), IEEE 802.1Q (VLAN tagging) Type and Rate: Thunderbolt 3 - 40 Gbit/s This Thunderbolt 3 to fiber network adapter connects your Thunderbolt 3 enabled device to a 10GbE network. The adapter combines the Thunderbolt 3 technology of TB31PCIEX16 with the 10GbE dual-fiber connection of PEX20000SFPI (Intel 82599 chipset). The assembled adapter features one DisplayPort output, one additional Thunderbolt 3 port, and two open 10GbE SFP+ slots. Mission-critical connectivity This Thunderbolt 3 to fiber network adapter is the perfect solution for your mission-critical operations. The network adapter supports 802.1Q VLAN tagging for better bandwidth, 802.3ad link aggregation for greater network speeds, network redundancy support for reliability, and two 10G fiber connections through open SFP+ fiber slots for building a custom setup. Install and assemble with ease Requiring only a Phillips type screwdriver and your choice of SFPs, this Thunderbolt 3 to 10G fiber network adapter can be assembled and connected in minutes. Change up your chassis The Thunderbolt 3 chassis not only pairs well with the 10G fiber network card--you can swap in other PCIe cards to help support other functionality and performance. With the extra TB3 port and DP output built into the chassis, you will always have the ability to hook up extended displays to multitask effortlessly.

Compatibility
Operating Systems Supported	Windows 7, 8, 8.1, 10 Windows Server 2008 R2, 2012, 2012 R2, 2016 Linux 2.6.24 to 4.11.x LTS Versions only

Features
Features	This Thunderbolt 3 network adapter connects your Thunderbolt 3 enabled device to a 10GbE fiber network via a PCIe expansion chassis Get the increased bandwidth, speed, reliability and security of a 10 GbE NIC, using your computer’s Thunderbolt 3 port Upgrade your peripherals without having to upgrade your chassis, by just switching out your PCIe card Assemble easily, with just a screwdriver Note: The expansion chassis does not support video cards. This expansion chassis does not provide full power delivery but will provide 15W of power, resulting in a slow charge to some laptops, such as MacBook Pro. When the dock is connected to your host laptop, a charging icon may appear on your laptop's screen. This is only sufficient enough to charge your laptop in sleep state, and charging will require an extended time period. 5K support can only be achieved using a Thunderbolt 3 5K monitor. DisplayPort 5K monitors will not work with this expansion chassis. A 4K-capable display is required to achieve 4K x 2K resolution (4K is also known as 4K x 2K). Certain monitors may be limited to 4K at 30Hz when connecting through DisplayPort. These monitors include the following models: Dell P2715Q, Viewsonic VX2475Smhl-4K, Philips 288P6LJEB, LG 31MU97C-B, Asus PB287Q (these models will need to be set to 4K at 30Hz). When connecting a display to one of the Thunderbolt 3 USB-C ports, a USB-C video adapter might be required depending on the input of your display. Secondary Thunderbolt 3 port can also be used to connect USB 3.1 (10Gbps) USB-Type C devices, such as USB 3.1 Hubs. Backwards compatible with USB 3.0 (USB 3.1 Gen 1), and USB 2.0.
