TP-Link TL-SM5310-T | 10GBase-T RJ45 SFP+ Module | 10G Copper SFP+ Transceiver | SFP+ to Ethernet | Plug and Play | Hot Pluggable | Up to 30m distance| | Durable Metal Casing | Versatile Compatibility

I use this TP-Link TL-FM531 module in the SFP+ WAN port of my Ubiquiti UDM Pro Max to connect directly to the Verizon ONT. My internet plan is 2 Gbps. On the same plan, using the 2.5 G Ethernet WAN port, real speeds were below 2.3 Gbps. After switching to this TP-Link transceiver, speed tests consistently show 2.4–2.55 Gbps - faster and completely stable. I haven’t tested 10 Gbps yet (no other 10G devices on my network), but for 2 Gbps service it performs flawlessly. Plug-and-play installation - it connected instantly and has been running rock-solid for months without a single issue.

Great way to turn an SFP slot into Ethernet...Works as described!

Solved my issue for connecting LAN to new 10g switch using cat6. Completed my conversion of small office network behind pfSense. Getting full 3g WAN transfers split across multiple 2.5G NIC workstations.

Works as intended in my TP-Link switches (SG3428XMP and SG3210X2) . Carries a 10GB connection over twisted pair cable. As this is the only 10GB copper module I've used, I'm not sure if all 10GB SFP+ modules get as hot as this on, but it gets almost too hot to touch. Time will tell how long the module lasts. Hoping it's a very long time as I have no way to run fiber optic cable in my walls. I'm stuck with the CAT5e that's in there. You can get a 10GB connection on CAT5e, but just on a short runs of cable. My total run is about 75 feet and I'm using CAT6A patch cables from the switch to the patch panel and from the wall jack in my office to the switch in my office. CAT5e in the walls, unfortunately.

If you’re building or expanding an AV-over-IP or enterprise network and need reliable 10G copper uplinks, TP-Link’s 10G copper SFP+ modules get the job done—cleanly and without drama. In real-world AV deployments, these have proven to be stable and predictable, which is exactly what you want at the core or distribution layer. They negotiate properly, maintain consistent throughput, and don’t introduce the weird link drops or heat issues you sometimes see with off-brand modules. Pop them in, they light up, and they just work. They’re a great fit for short-run 10G connections where copper makes sense—rack-to-rack, switch-to-server, or uplinks in environments where pulling fiber isn’t practical. Build quality feels solid, and compatibility has been straightforward with supported hardware. Bottom line: these are dependable, professional-grade 10G copper SFP+ uplinks at a reasonable price point. If you want performance without surprises—and gear that behaves the way network gear should—TP-Link delivers here.

Works perfect, had another brand and my UniFi was giving me errors. This one works perfect with my UniFi Dream Machine SE to connect to the 2.5G Flex mini. On the UDM side shows as 10G but handshakes with my Flex mini at 2.5. Exactly what I needed.

Works as advertised in a QNAP M3216R-8S8T switch. Had to do a simple reboot after the initial installation, and it's been fine since March of 2024. Unit is on 24/7. Gets close to rated speed and steady transfer of large backup images (30-68GB) on my 10GbE copper network with nvme ssds at each end. Insertion fit is easy, yet snug. Locks easily. Barely warm to the touch, not hot like many other SFP+ modules. Quite pleased with it... will purchase more as the network expands.

Working great for connecting a Ubiquiti UDM Pro to the Internet service provider’s 10Gb fiber modem. Speeds are as expected. Easy install, reasonable price, and quick delivery.

I think the market for 10GBase-T is a bit premature. I've tried several vendors of these SFP+ modules and when they work, they work for a short period of time and then dies. This particular device failed after 3 days of operation. When I removed the SFP from its cage, it was very hot and I was seeing several DDM log captures that the SFP was failing. Although interesting for use cases that have Cat6(a) already in place, I suggest avoiding 10GBase-T altogether. At least for now. And for those that are going to attempt to get 10G to their host devices on Cat6(a), these device add a bit of latency. Just sayin..... up to you to try but for me any 10GBase-T I try will be Enterprise grade only going forward. If I even want to revisit this.

In general the sfp+ works great, they are running a bit hot in my switch. My one has a low voltage warning (DDM) after contact tp support any divination of 20milivolt is fine. I am happy .
