I have been purchasing 10Gtek optics and DACS for some time, in 1G/10G and 25G variants and they have always been excellent. I would recommend them to anyone. ### ⭐⭐⭐ Doesn't auto-negotiate down to 10Gb as details say it can....? *by on Reviewed in the United Kingdom 3 November 2025* Got one of these in a Mellanox ConnectX-4-Lx card and it won't negotiate down to 10Gb talking to a 10gb 10Gtek module in my TP-Link 3008 - don't know why as it's supposed to be able to. Updated the card with the latest firmware (in case that was the issue) and still no joy. Gave it 3 stars as I will keep the module and when I upgrade the switch to 25Gbe I will try again then and my other 10Gtek modules have worked flawlessly so maybe it's user error? ### ⭐⭐ Major compatibility issues with Ubiquiti *by on Reviewed in the Netherlands 26 June 2024* Beware before purchase!Initially I ordered 2 and they seem to work fine until I start to notice performance issues. It took me some time to trace the issue down to an incompatibility between these transceivers and Ubiquiti switches. I ordered 4 more which all show the same major performance issues (down to ~ 30 Mbps under some circumstances. I have tried several other brands including Ubiquiti transceivers and they all work fine. None of these 10GTek work without a problem. I mailed support via their website, They boast good technical support but I never got a reply. I can return 4, but the first order I can no longer return and there is no support. Think twice! Pay a little more. ## Frequently Bought Together - 10Gtek 25G SFP28 SFP+ SR Transceiver, 25GBase-SR Duplex LC MMF Optical Module for Cisco SFP-25G-SR-S, 850nm, DDM, up to 100m - FLYPROFiber- OM4 Fiber Patch Cable 1M/3ft, LC to LC Multimode Duplex, 50/125um LSZH 10GB/40GB/100GB, Length: 0.2m-100m - FLYPROFiber- LC to LC Fiber Patch Cable 1M/3ft, OM3 Multimode Fiber Optic Cable Cord, 10GB/40GB, Duplex, 50/125um, LSZH, Options: 0.2m-200m --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/522317055-10gtek-25gb-sfp28-sr-multimode-module-850nm-mmf-fiber-lc](https://www.desertcart.gr/products/522317055-10gtek-25gb-sfp28-sr-multimode-module-850nm-mmf-fiber-lc) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-02*
