Product Description
10GBASE-T Thunderbolt 5 to 10 Gigabit Ethernet Adapter with Multi-Gigabit Support
Solo10G T5 gives today's Thunderbolt 5 computers a professional, full-bandwidth 10GbE network connection while maintaining broad compatibility with Thunderbolt 4 and USB4 computers, as well as iPad Pro (M series). Its Thunderbolt 5 interface provides more than enough PCIe bandwidth to run the 10Gb port at full speed. Bus-powered and compact, it delivers reliable 10GbE performance for high-speed file transfers, shared storage, video workflows, and demanding production networks.
Key Features
- Adds a 10GBASE-T RJ45 10 Gigabit Ethernet port to computers with Thunderbolt or USB4 ports
- Multi-Gigabit/NBASE-T support: 10G, 5G, 2.5G, and 1G
- Bus-powered operation requiring just 7.5W, no external power adapter needed
- Thunderbolt certified: authenticated firmware and rigorous compatibility testing, unlike typical uncertified USB4 adapters
- Solid aluminium enclosure, fanless and silent, small enough to fit in a spare pocket
- Replaceable captive 0.3-metre Thunderbolt 5 cable
- AVB (IEEE 802.1Qav) support on Mac with an AVB-capable switch or router
- Easy setup using your operating system's own network settings tools
- 2-year product warranty and free lifetime technical support
Connect to 10GbE Infrastructure
Solo10G T5 is equipped with a single RJ45 socket, enabling it to connect to 10GbE infrastructure via inexpensive Cat 6 or Cat 6A copper cabling, at distances up to 55 meters (Cat 6) or 100 meters (Cat 6A).
Multi-Gigabit Performance, No Rewiring Required
Already have Cat 5e cabling? Solo10G T5 supports the NBASE-T standard, delivering 2.5Gb and 5Gb link speeds, plus 1000BASE-T, at up to 100 meters over existing Cat 5e (or better) cables when paired with a multi-gigabit compatible switch, router, or NAS.
Bus-Powered, No Adapter Needed
Requiring no power adapter, Solo10G T5 consumes just 7.5W of bus power, leaving your computer enough power available to connect another bus-powered Thunderbolt device, such as a Thunderbolt 5 SSD.
Rugged, Silent, Pocketable
Featuring a solid aluminium enclosure, Solo10G T5 runs cool without a fan, unlike many USB4 10Gb Ethernet adapters, so it is silent in noise-sensitive environments. Measuring just 3.1 inches wide by 4.5 inches deep by 1.1 inches tall, it is small enough to drop into a spare pocket in your equipment bag.
Thunderbolt Certified for Real Security
Thunderbolt certification means the Solo10G T5's hardware-based, encrypted device firmware is part of a controlled, authenticated Thunderbolt implementation, and only verified manufacturer updates can make changes. Generic USB4 peripherals rely on alterable open firmware implementations that are not subject to the same Thunderbolt certification and authentication requirements, increasing supply-chain and endpoint-security concerns. For organisations that take endpoint and network security seriously, the Thunderbolt certified Solo10G T5 provides a superior level of confidence compared with uncertified USB4 alternatives.
Proven Design, Pro Quality
The original Solo10G Thunderbolt adapter became a best-selling 10Gb Ethernet adapter in professional video environments because of its proven reliability. Sonnet upgraded it with Thunderbolt 5 technology while retaining the same Marvell 10GbE controller and stable drivers, ensuring reliable operation across platforms.
Replaceable Captive Thunderbolt 5 Cable
The included Thunderbolt 5 cable supports Thunderbolt 5's full PCIe bandwidth. A secured internal Thunderbolt connector keeps the cable firmly connected inside the adapter, and if the need arises you can install an approved replacement cable available from Sonnet or a Sonnet-authorised reseller.

Product Q&A
Q: What is the Sonnet Solo10G T5 Thunderbolt 5 10Gb Ethernet adapter used for?
A: It adds a 10GBASE-T RJ45 Ethernet port to computers with Thunderbolt or USB4 ports, for fast file transfers, shared storage, video workflows, and demanding production networks. It connects to 10GbE infrastructure over Cat 6 or Cat 6A copper cabling.
Q: Do I need a Thunderbolt 5 computer to use the Solo10G T5?
A: No. It is built for Thunderbolt 5 but also works with Macs that have Thunderbolt 5, Thunderbolt 4, Thunderbolt/USB4, or Thunderbolt 3 ports (macOS 15 or later), Windows 11 25H2 or later and Linux kernel 6.6 or later computers with Thunderbolt 5, Thunderbolt 4, or USB4 ports, and iPad Pro (M series).
Q: Does the Solo10G T5 need a power adapter?
A: No. It is bus-powered and draws just 7.5W from the host's Thunderbolt port, which leaves your computer enough power to connect another bus-powered Thunderbolt device, such as a Thunderbolt 5 SSD.
Q: What cable do I need for the Solo10G T5, and how far will it reach?
A: For 10GBASE-T, use Cat 6 cable for up to 55 metres or Cat 6A cable for up to 100 metres. It also supports 5GBASE-T, 2.5GBASE-T, and 1000BASE-T at up to 100 metres over Cat 5e (or better) cabling. The 2.5Gb and 5Gb speeds need a multi-gigabit compatible switch, router, or NAS.
Q: Does the Solo10G T5 support Wake-on-LAN?
A: No, Wake-on-LAN is not supported.
