Compatible with Mac, Windows, and Linux, it supports multi-gigabit auto-negotiation (10G/5G/2.5G/1G/100Mbps) over existing RJ45 cabling. Its fanless, ventilated aluminum design ensures silent, cool operation, while bus-powered portability and plug-and-play setup make it ideal for creative professionals seeking to dramatically boost network performance and collaboration efficiency. ## Description Product Description Blazing-fast: over 900MB/s real-world tested transfer speed for large file transfers, video editing, and live streaming gaming sessions Compatible: use with any Thunderbolt 3 or Thunderbolt 4-equipped Mac or Windows computer Capable: up to 100-meter cable distance with Cat6a for 10G, Cat6 for 5G, and Cat5e for 2.5G Smart: supports auto-negotiation for 10Gb/s, 5Gb/s, 2.5Gb/s, 1Gb/s and 100Mb/s Base-T Ethernet standards Accessible: Wake-on-LAN ready for remote access of home or work computer AVB ready: perfect for use in pro audio and video applications where synchronization of data streams is critical Cost effective: 2.5GBASE-T and 5GBASE-T technology (formerly NBASE-T) provides up to 500% faster performance over existing cabling Energy efficient: supports IEEE 802.3az for low computer bus power Cool: ventilated aluminum heatsink housing maximizes heat dissipating airflow Silent: fanless for noise sensitive environments Durable: rubber sleeve protects during portable use Easy setup: connect the included detachable Thunderbolt 3 cable and connect to your network ENGAGE WARP SPEED FILE TRANSFERS The Thunderbolt 3 10G Ethernet Adapter opens up a world of high-performance network connectivity to Thunderbolt 3-equipped notebooks that lack built-in Ethernet connectivity and to desktop machines handcuffed by a built-in 1Gb/s Ethernet port like the iMac 2017, Mac mini 2018, M-series iMacs, laptops, pc laptops and All-In-One PCs. Connecting the OWC Thunderbolt 3 10G Ethernet Adapter to your Thunderbolt 3-equipped Mac or PC adds warp speed file transfers to your workflow. Now you can access 10GBASE-T 10Gb Ethernet networks and other devices, such as a Network Attached Storage (NAS) system, to transfer large multimedia files at over 900MB/s real-world speed. While improving project efficiency and workgroup collaboration with the quickest network connection available, the adapter is also backwards compatible with other Ethernet standards including 5GBASE-T, 2.5GBASE-T, 1000BASE-T, and 100BASE-Tx. MAXIMIZES SOHO NETWORKS Without having to incur the extra expense of a full 10Gb Ethernet network, it’s becoming common for budget-constrained, yet performance-oriented creative professionals in small or home offices to connect to a 2.5 – 5Gb/s equipped router or switch. Unfortunately, these pros are often limited to Gigabit Ethernet (1Gb/s) speed by their computer. By simply adding the Thunderbolt 3 10G Ethernet Adapter to their machine, photographers, videographers, musicians, and other creative pros can now enjoy greater signal reliability, stability, and security with up to 5x faster speed on 2.5 – 5Gb/s networks and up to 10x faster speed on 10Gb Ethernet networks. DRAMATICALLY INCREASES PERFORMANCE AND ROI OF EXISTING NETWORK With an ideal combination of affordability and performance, most wired local area networks installed over the past two decades utilize Cat 5e or Cat 6 copper cabling. Unfortunately, these setups are limited to a maximum 1Gb/s speed. Thanks to its built-in 2.5GBASE-T and 5GBASE-T technology (formerly NBASE-T), the Thunderbolt 3 10G Ethernet Adapter can deliver up to 10Gb/s speed over existing cabling for up to a 500% performance increase and maximum infrastructure ROI. Time-sensitive data such as audio and video media streams require Audio Video Bridging (IEEE 802.1Qav, AVB) ready gear. No sweat…the Thunderbolt 3 10G Ethernet Adapter can stream vast volumes of high-quality data to multiple destinations in real-time with very low latency over existing network cable. RUNS SILENTLY COOL WITH RUGGED AND EFFICIENT PORTABILITY Featuring a unique ventilated design that maximizes airflow, the Thunderbolt 3 10G Ethernet Adapter’s rugged aluminum housing works as a heat sink to operate silently cool without needing a fan. The adapter draws its power from the Thunderbolt 3 port with Energy-Efficient Ethernet support for low computer-power use and no AC adapter needed. Further complimenting its portable potential is a rubber sleeve to keep the adapter safe from bumps and bruises when thrown into a backpack or gear bag. EXISTING CABLE COMPATIBLE When you need to access an older or even state-of-the-art network, the Thunderbolt 3 10G Ethernet Adapter’s RJ45 socket will connect you to a wide range of existing cabling infrastructures ranging from Cat 5 to Cat 7. Review: WOW! (Works well with Caldighit TB3+ dock) - ***** New Update A change to Kasimo Cat8 Ethernet cables has made a massive difference and there is a constant 250 MBPS transfer rate now when copying to/from a NAS equipped with 10GBe,before there was a reduction in speed after few minutes (and about 40GB transfer). ****Update It seems that when doing large transfers (say 150GB+,) there seems to be a slowdown in performance which I believe is either thermal throttling of the 10GBe adapter or of the WD My Book Pro (Raid 0). I bought this for my 16" MBP, I decided (To reduce clutter) to utilise the spare Thunderbolt 3 slot on the Caldigit Dock. Plugged it in, set Jumbo Frames to 9000, and made this the first in the oder priority in the Mac's Network Settings and connected via Cat6 to a Unifi 48 port switch. I cannot believe how much quicker everything feels (I was using the Caldigit 1GBe connection to a full Unifi setup and it wasn't slow), but websites appear instantly (Virgin Cable 380Mbps Down 38Mbps up). And transferring data from my QNAP TS453A NAS (with 4x 1GBe ports with trunking) was incredibly fast. I transferred Movie files both too and from the NAS via WD My Book Pro (2x4 WD Black Drives in a RAID 0, giving around 270MBs via Black Magic). I am more than impressed. One of the best IT purchases I have ever made. Review: Keeps disconnecting and requires unplugging several times a day - I ordered several of them to allow some iMacs to connect to our network at 10Gbps through their thunderbolt ports. They are ok while they work, however, after an hour of high speed data transfer you have to go and unplug it and plug it again.. this is observed on all devices we have I don't recommend buying them ## Features - Securely and cost-effectively connect your Thunderbolt 3 equipped Mac or Windows PC to high-performance wired networks delivering up to 10 times the performance of Gigabit Ethernet - Silent Operation with Robust, Heat-Dissipative Design.

The full path should be 10gb. **Q: does this work for usb-c and can i use a usb-c to usb-a cable for usb 3.0 type a cable into usb 3.0 port on older 2015 macbook pro 11,4?** A: It requires a direct connection to the computer via TB3. USB-C will not work. **Q: Is this the current version with the detachable cable or the old version with the captive cable? The part number matches the new version.** A: Hello, This should be the new version with the detachable cable. The page just needs to be updated with the current images of the unit. **Q: Will this work with a thunderbolt 2 device/ 2-3 adapter?** A: Hello, To use this bus-powered device on older Thunderbolt and Thunderbolt 2 computers, it has to be connected to the second Thunderbolt 3 port on another self-powered Thunderbolt 3 device. If connected directly to a host the Thunderbolt 3 to Thunderbolt 2 adapter, bus-power is insufficient. An example configuration is: Thunderbolt 2 Mac with macOS 10.13.6 or above > Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter > self-powered Thunderbolt 3 device with two TB3 ports > OWC Thunderbolt 3 10G Ethernet Adapter. ## Customer Reviews ### ⭐⭐⭐⭐⭐ WOW!
