## Overview

The 10GTEK SFP+ to RJ45 module delivers ultra-fast multi-rate data speeds up to 10Gbps over CAT6a/CAT7 copper cables with a 30-meter reach.

Tested for cool, reliable performance, this module is the perfect upgrade for professionals demanding seamless, high-speed connectivity in their network infrastructure.

## 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: Functional and versatile SFP copper transceiver - This transceiver worked great in another switch I purchased from desertcart with a no-name Chinese company. I also used it in media converters (fiber to copper) for connecting directly to my computer. It automatically negotiates the speed and was extremely easy to install. It was also compatible in my Intel X710 network card that runs the network for my server to connect to my coax cable modem. The fact this SFP supports multiple speed options is also great because I connected it to a switch with only 10G but it worked fine connected to a 2.5G copper RJ45 jack without any errors, so it must negotiate and rate limit within itself.
Review: Great option for SFP+ to 10G-BaseT - I ordered the ASF-10G2-T model, and wanted to use it with my Juniper EX switch, so I immediately messaged the 10Gtek support seller (not for desertcart direct sale, must choose 10Gtek) with my desertcart order number and the information that I wanted my SFP+ modules coded to Juniper specs. The seller ( https://www.desertcart.com/sp?marketplaceSeller=1&seller=AE2OZG2NN3099 ) immediately responded and confirmed. I received my order directly from China (less than a week), plugged them into SFP0 and SFP2 on my Juniper EX switch. Worked first time, and link-up with my Intel 10Gig interface on my server without any manual configuration. Great Job 10GTek for a great value quality product with customization and customer service.

### ⭐⭐⭐⭐⭐ Runs hot
*by K***S on 29 June 2025*

Works like a charm, but very hot. Stayed within the documented temperature range/norms when I checked with my thermal camera so I don't expect any issues. The heat makes me nervous for my kids long term however, so I am using this as a short term stopgap.
