LightOne 25GbE Thunderbolt Dock
25GbE workstation dock. One Thunderbolt cable.
Dual SFP28 networking, 85W host charging, 140W PD input, DisplayPort, card readers, USB expansion, and Thunderbolt daisy-chain in one compact dock.
Thunderbolt carries the host link while power, network, display, USB, and cards stay organized around one dock.
Active cooling and a metal enclosure help keep long transfers credible beyond a short benchmark run.

“the best dock we have seen”
STH reported around 21-22Gbps in testing
Dual SFP28 and dock I/O stood out
Early fan-noise feedback has been addressed with the improved fan setup

Real setup context
Seen in a Mac mini server build.
LightOne appears in jakkuh's public Mac mini server build around 4:20-5:00. If that setup brought you here, start with the Explorer and choose the network module that matches your switch or NAS.
Why $399
A 25GbE adapter, workstation dock, card reader, display output, USB hub, and host charging path in one device.
Complete the network link
Pick the cable or transceiver that matches your NAS, switch, workstation, distance, and thermal needs.
Dual SFP28, DisplayPort, PD input, fan, and USB live in one dock.
Why not the cheap route?
Because LightOne replaces the adapter stack, not just the Ethernet port.
A small network adapter is fine for occasional Ethernet. LightOne is for buyers who need 25GbE-class networking and still want the daily dock: charging, display, card ingest, USB expansion, and a cleaner desk.
Dual SFP28 network flexibility
85W host charging
One dock fewer boxes
One job. More boxes.
- Usually single-port and lower-speed
- No host charging or display output
- Leaves card reader, USB hub, and power separate
- Often built for occasional use, not heavy transfers
25GbE plus the workstation dock around it.
- Dual SFP28 for fast NAS, SAN, lab, or direct-attached network workflows
- Up to 85W host charging from a 140W USB-C PD input
- DisplayPort, SD/TF, USB-A, USB-C, and Thunderbolt daisy-chain
- Launch price: $399.00
Ports, but not 25GbE.
- Great for office peripherals
- Network port often stops at 1GbE or 2.5GbE
- External 10/25GbE adapter still needed
- More desk clutter when storage traffic grows
Dual 25GbE SFP28
SFP fiber, DAC, or RJ45 transceiver. Choose the link the job needs.
Use SFP28 for high-speed NAS, shared editing storage, lab networking, or direct workstation links. With compatible modules, the dock can also step into 1/2.5/5/10GbE RJ45 environments.
25GbE SFP28
10GbE via adapter
Direct attach
Low-latency workflows
One desk cable
Power, display, network, USB, and cards meet in one place.
When you dock a mobile workstation, the value is not only speed. It is removing the daily ritual of reconnecting power, network, readers, drives, and display one by one.
Power delivery
140W in. Up to 85W back to the host.
The dedicated USB-C PD input gives the dock its power budget while the host receives up to 85W charging. It is a cleaner layout for laptops that need serious I/O without living on battery.

TB daisy-chain support
Port system
Not every port has to be glamorous. It just has to be there.
Two USB-C ports, four USB-A 3.0 ports, UHS SD and TF readers up to 300MB/s, DisplayPort up to 4K, and Thunderbolt daisy-chaining keep everyday devices close to the same high-speed desk.
Who it is for
For people whose network is part of the workstation now.
LightOne makes the most sense when fast shared storage, field ingest, or lab networking is part of the workday, not an occasional accessory.
Video editors and color suites
Move camera media, project caches, and shared storage traffic without turning the desk into a chain of adapters.
NAS and homelab users
Connect to high-speed storage, lab switches, or direct workstation links with SFP28 flexibility.
IT, field, and engineering teams
Carry one dock that handles fast network tests, card ingest, USB devices, display output, and charging.
Mobile workstation owners
Dock quickly, charge the host, attach a monitor, and keep fast network access ready for the next job.
Before you buy
Make sure the rest of the chain is ready for 25GbE.
LightOne is a serious dock, but network speed still depends on the host, cable, SFP28 module or DAC, switch/NAS, storage, and OS configuration.
What host do I need?
Use a Thunderbolt 3/4 or high-bandwidth USB4 workstation. Standard USB-only hosts are not the right match for this product.
Are SFP28 modules included?
No. Choose the DAC cable, optical module, or RJ45 transceiver that matches your switch, NAS, cable length, and thermal requirements.
Why dual SFP28 if Thunderbolt is shared?
Dual ports give you topology flexibility: storage plus management, direct attach plus switch, failover setups, or separate networks. Real throughput depends on the full Thunderbolt and network chain.
Is this the right product if I only need Ethernet?
If you only need occasional low-speed Ethernet, a small adapter is cheaper. LightOne makes sense when you also need charging, display, card ingest, USB expansion, and sustained high-speed networking.
