1.25/2.5/5/10G-T SFP+ to RJ45 CAT.6a Copper Transceiver, Auto-Negotiation SFP+ Ethernet Module, up to 30-Meter, for Cisco SFP-10G-T-S, Ubiquiti UniFi UF-RJ45-10G, Netgear AXM765 and More

Works great. And when I plugged in a 1ge, it stepped it down so this unit will be very versatile

Works great in my Cisco 3560cx-12pd. Great throughput to SAN/NAS lab network.

Works perfectly with the QNAP device if your wondering. I didnt know which one to use so I started with the cisco version and it works flawlessly.

I have a Unify Dream Pro console that has two 10G SFP+ ports (WAN and LAN). I recently upgraded to 2G internet. The downlink speed is as expected, about 2.2 Gbs but the uplink speed is a measly 82.7 Mbps. Without these devices, I get in the high 900Mbps on the 1G WAN port. I am returning this item.

With UF-RJ45-10G you can use from 1GB to 10GB, this is just a expensive, but cheap copy that only allows 10GB.

No issues so far, if I encounter any problems in the future Ill keep you updated. So far no issues.

Exact same issue as other modules. Slow incredibly slow uploads. As in < 100 mbps. On a symmetric fiber 2gig connection -- downloads are fine, uploads are not -- same story with wiitek and a few others,, it should have been verified to fully support the 803.1bz standard -- it doesnt. The one that works is the MikroTik S+RJ10.

Fit perfect into my 10g slot and my cat6 cable slid right in

Outside of being put of stock when I need them most of the time they are amazing.

Not sure if I got a faulty one or not but I’ve been running tests for an hour now and I can’t even get close to 1G speeds. On my computer it’s says it is connected at 10G but when I actually do anything it’s super slow . I even went down to only 1 meter and still terrible speeds. Speed test for example on a regular 1G Ethernet cable I can get 950Mbps but when I use the 10G TX i only get 325Mbps.
