Dual-port 10GBASE-T 10 Gigabit Ethernet Thunderbolt Adapter

Key Features
  • Adds 10GBASE-T 10GbE Connectivity —Simply powerful way to add dual RJ45 10 Gigabit Ethernet ports to your computer with Thunderbolt 3 ports
  • Cost Effective —Connects to 10GbE infrastructure via inexpensive CAT-6 or CAT-6A cables at distances up to 55 or 100 meters, respectively
  • Easy Setup —Configured through macOS Network control panel or Windows Device ManagerLink-Aggregation Support
  • Supports Transparent Failover —Keeps your computer connected in case a single cable is disconnected or one of the ports fails
  • Supports Link Aggregation (Teaming) —Increases throughput beyond what a single connection can sustain in some applications
  • Small and Nearly Noiseless —Adapter is compact enough to sit on most any work surface, and quiet enough for use in noise-sensitive environments
  • Rugged Aluminum Housing —Provides robust and secure protection
  • Two Thunderbolt 3 Ports —One port reserved for connection to the computer; second port supports daisy-chaining of up to five additional Thunderbolt(4) devices to your computer, attaching a single USB(5) peripheral device, or connecting up to two 4K displays or one 5K display
  • Power for Peripherals —Provides up to 15W of power to connected peripherals
  • Thunderbolt 3 Cable & ThunderLok 3 Included —Includes 0.5-meter Thunderbolt 3 (40Gbps) cable and ThunderLok 3 Thunderbolt connector retainer clip to secure cable from accidental disconnections

  • Ürün Tanımı
  • Teknik Özellikler

The Twin10G Thunderbolt 3 Edition adapter is equipped with two RJ45 ports, enabling it to connect to 10GbE infrastructure via inexpensive CAT-6 or CAT-6A copper cabling at distances up to 55 or 100 meters, respectively.

Small and Nearly Noiseless
The Twin10G Thunderbolt 3 Edition adapter is compact enough to easily fit in most workspaces, yet large enough to support proper airflow inside the case—its design enables the adapter’s temperature-controlled, variable-speed fan to keep the adapter running cool and whisper-quiet at all times, making it suitable for use in noise-sensitive environments. Constructed of rugged and lightweight aluminum, the adapter’s outer shell securely protects the inner circuitry.

Simplified Setup
Just connect the Twin10G Thunderbolt 3 Edition adapter to your computer via the included Thunderbolt 3 (40Gbps) cable, download and install a driver, connect the adapter to the network switch or directly to 10GbE-enabled storage via CAT-6 or CAT-6A cables, and configure the adapter’s settings through the macOS® Network control panel or Windows Device Manager.

Thunderbolt 3 — The USB-C That Does It All
The Twin10G Thunderbolt 3 Edition adapter includes two Thunderbolt 3 ports; the first connects the adapter to your computer, while the second supports daisy-chaining of up to five additional Thunderbolt peripheral devices to a single port on your computer.

Intelligent Operation
The Twin10G Thunderbolt 3 Edition adapter attains its high throughput performance and low host-CPU utilization through functions such as 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 offloading. These processes enable your computer to perform better while large files transfers or high I/O operations take place.

Thunderbolt 3 (40Gbps) Cable and ThunderLok 3 Included
The Twin10G Thunderbolt 3 Edition adapter includes a 0.5-meter Thunderbolt 3 cable to connect to your computer, and a Sonnet ThunderLok 3 Thunderbolt connector retainer clip to secure the cable to the adapter. Sonnet’s ThunderLok 3 helps prevent accidental cable disconnects that can lead to data loss, securing the Thunderbolt cable to the adapter. ThunderLok 3 is easy to install and use—just slide it over one of the cable’s connectors, plug in the connector, and then secure it to the adapter by turning a thumbscrew. Because ThunderLok doesn’t attach to the connector, it remains on the cable and won’t get lost when not in use.
