Thunderbolt 3 PCIe enclosure with dual SFP+

This enclosure adds a removable PCIe x16 card to a Thunderbolt 3 host, providing two open SFP+ ports for 10 Gbps fiber networking. A DisplayPort output and a 92 mm cooling fan are integrated into the aluminium and steel chassis. The bundle includes a 65 W universal AC adapter, a Thunderbolt 3 cable, a low-profile bracket and rubber feet.

Verify host port and operating system support

The unit requires a Thunderbolt 3 USB-C port capable of 40 Gbps signalling and x4 PCIe 3.0 bandwidth. Supported systems are Windows 7, 8, 8.1 and 10 plus Windows Server 2008 R2, 2012, 2012 R2 and 2016; Linux kernels 2.6.24 through 4.11.x LTS only. Confirm that your SFP+ transceivers match the 10 Gbps full-duplex specification and that jumbo frames up to 15K are acceptable for your network.

Suits users adding 10 GbE fiber via Thunderbolt 3

Ideal for workstations or laptops that need a 10 Gbps fiber link and have a spare Thunderbolt 3 port. Not suited for builds lacking Thunderbolt 3, for installations requiring PCIe cards larger than a single slot, or for environments running unsupported operating systems or newer Linux kernels beyond 4.11.x LTS.

Questions about this item

What comes in the box and what do I need to add for a working 10 Gbps fiber link?

The box includes the Thunderbolt 3 enclosure, a 40 Gbps Thunderbolt 3 cable, a pre-installed PCIe 10GBase fiber card with two SFP+ slots, a 65 W universal power adapter, rubber feet, a low-profile bracket and two quick-start guides. You must supply SFP+ transceivers and fiber patch cables to complete the 10 Gbps network connection.

The card has two SFP+ ports — should I populate one or both?

Each SFP+ slot accepts a 10 Gbps transceiver, so you can run a single 10 Gbps link or use both ports for link aggregation or separate networks. The chassis delivers up to 20 Gbps full-duplex to the card, so two 10 Gbps connections can operate simultaneously without bottleneck.

The specs list 40 Gbps for the chassis and 20 Gbps for the card — what throughput will I actually see on the wire?

The Thunderbolt 3 link to the host runs at 40 Gbps, but the included PCIe card is limited to 20 Gbps full-duplex (x4 PCIe 3.0, 3.94 GB/s). Each SFP+ port is rated for 10 Gbps, so the maximum real-world network throughput per port is 10 Gbps.
