## Description

This 10G SFP+ RJ-45 module supports multi-rate operation from 1.25G up to 10Gb/s and reaches up to 30 meters over CAT.6a or CAT.7 cable, with an operating temperature range of 0°C to 70°C. It is compatible with Cisco, Fortinet, and Ubiquiti switches as a drop-in replacement for Cisco SFP-10G-T-X. Please note this module is not compatible with Ubiquiti US-48-500W, HP-ProCurve, HP-H3C, HP-Aruba, Intel, Arista, Mellanox, Dell Force10, Extreme, Brocade, or Juniper switches. The hot-swappable design allows for easy installation into a 10G SFP+ port, and each unit is tested on Cisco and Ubiquiti switches for reliable performance.

Review: Runs cool 😎 - Was hunting for a 10G-T SFP and found a lot of people complaining that they run hot… stumbled across some posts that this SFP runs significantly cooler then others and I took a punt… installed in a Mikrotik switch, looked at the health of the SFP and was happily surprised that the temperature reported as 51c while xfering data at 10G speed. Highly recommended and I’m now looking to buy a few more to put in a CRS309.
Review: Works as advertised, good for different speed nics! - Works as expected. I needed 2.5gbs and didn't realize the 10gbs ones auto negotiate down to 1gbs if you don't have a 10gbs nic. Also all the technical info shows up on the switch with these, their old ones did not (could be because I was using a 10gbs on autoed down to 1gbs?). Then I upgraded my internet to 2gbs, now I am seeing internet speeds around 2.5gbs, amazing! I have not had to do file transfers in a while, I was using a 10gb pcie card in my old pc, can't use it in this one.

### ⭐ Avoid
*by T***E on 26 August 2025*

Device couldn't auto negotiate to 1.25 Gbps link speed. When I tried to force the link to that speed, it wouldn't work at all. No matter what I tried, the device just stayed stuck at 10 Gbps and wouldn't auto-negotiate to proper speeds when paired to any interface at varying link speeds. This caused issues when trying to communicate with my ISP via a WAN link. There is quite a bit of overhead as well, expect to lose about 200+ Mbps on your link, even when it does work. Runs hot. Quality is average. I feel like the compatibility isn't great. It was easy to setup. It has a single port capacity. All in all, I feel like this wasn't worth the price I paid.
