Review: Quality 10gig SFP+ Module - These are quality SFP+ modules which work extremely well in my Uniquiti Un-Fi 10gig aggregation switch. They run a little warm under heavy use, as do all RJ45 101gig SFP+ modules. I put a small heatsink on them to help keep them cool. I've never had a problem with them throttling or failing. I have a number of these.
Review: Excellent Performance and Value for Home Network Upgrade - I recently purchased the QSFPTEK 10G SFP+ RJ45 Module to upgrade my home network setup, and I have been thoroughly impressed with its performance. Installation was a breeze— it was truly plug-and-play with my Ubiquiti UDM Pro and switch US-8-150W, and I didn't face any compatibility issues. The data transfer speeds have significantly improved, making my large file transfers and streaming activities seamless and much faster. The build quality of the transceiver module feels sturdy and reliable. Additionally, the price point is very reasonable compared to other brands offering similar specs. It's been a couple of months since the installation, and I haven't encountered any disruptions or slowdowns in performance. For anyone looking to upgrade their network to 10GbE without breaking the bank, I highly recommend this product. It offers great value and excellent performance, all while being supported by a helpful customer service team at QSFPTEK who answered my queries promptly before the purchase. Pros: * Easy installation * Compatible with Ubiquiti equipment - UDM Pro - Port 11 * Reliable and fast performance * Cost-effective solution for 10GbE upgrade Cons: * None so far Overall, this transceiver is a fantastic choice for both tech enthusiasts and professionals looking to enhance their network infrastructure.

### ⭐⭐⭐⭐⭐ Reliable 10GbE Copper Transceiver, Runs Warm
*by B***S on January 30, 2025*

This SFP+ to RJ45 module worked flawlessly with my network setup, providing stable and consistent 10GbE connectivity. The build quality is solid, and installation was plug-and-play with no compatibility issues across my switch. Latency is low, and I haven't noticed any drops in throughput even during heavy file transfers. Like most copper-based SFP+ transceivers, it does run warm, but that’s expected for 10Gb over copper. Adding some airflow in the switch enclosure helps mitigate the heat buildup. If you need a cost-effective way to upgrade to 10Gb networking, this is a solid and reliable option.
