I've swapped my old coupler back which this one replaced and it went back to 1000.People will say it's the cable, but no, it's not. ### ⭐⭐⭐⭐⭐ Solid build, does exactly what you'd expect. *by J***N on Reviewed in the United States on July 7, 2019* This was exactly what I needed. Temperature sensors we buy have short cables and an RJ45 connector on it. So we use these to connect them to our own custom CAT6 to extend them to our switch. These work perfectly and are not flimsy whatsoever. Solid construction, well crafted, would probably survive if I stepped on them with my boots. I deployed all of them upon receipt and they all worked flawlessly. I would definitely buy these again. ### ⭐⭐⭐⭐⭐ Saved the day for me *by B***H on Reviewed in the United States on July 21, 2020* I don't even know what some of the things they list on the review mean? Rate it's sheerness? Strange, but here is why I'm writing a review. Have you ever spent a couple hours pulling a new network cable through a drop ceiling that was installed so close to the ceiling above it that you couldn't even lift the tiles only to find out your 50' cable was about 5 feet short? No? Just me then.... Ok, well if you have an ethernet cable that's too short I can tell you this one working great for me and it seems to be as fast or faster than the cable it's extending. I'm getting 600 Mbps through that line now. It was definitely worth double the price as well as it's working. --- ## 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.us/products/100548551-y-d-f-ethernet-cable-extender-rj45-coupler-in-line](https://www.desertcart.us/products/100548551-y-d-f-ethernet-cable-extender-rj45-coupler-in-line) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
