1.25/2.5/5/10G-T SFP+ to RJ45 Transceiver, Copper Ethernet Module Compatible for Cisco SFP-10G-T-S, MikroTik S+RJ10, Ubiquiti UF-RJ45-10G, Netgear AXM765, Netgear, TP-Link, Fortinet, 30m,1 PCS

Needed 2.5GbE connection for the WAN Cable modem as 1GbE port was limiting the throughput. The module was recognized with no issues. Improved ISP speeds.

Worked perfectly with Cisco catalyst 9300.

It works, arrived quickly. Not sure about the max speeds as I am only using this to connect 5g home internet to my gateway as a backup. So I will never get gig speeds on it.

Purchase: Nov 2023 Great SFP and it does push 10Gig. As other have mentioned, these do get hot. Even with the heat, the transceiver still hits 10 Gig speeds reliably for over a year now. If it works it works, I can't complain. Update: 10/17/2025 Still working great. I got these as a pair for my home lab and installed them onto a TRENDnet TEG-3102WS switch going to a 10 GiB NIC. Still zero issues. I recently put some passive heatsinks onto the transceivers, did that a couple days ago. Not that I had any heat related problems. I know I mentioned these heat up but it hasn't caused any issues as of yet. I'm mainly doing it for peace of mind. Now I'm shopping around for more heatsinks and I thought I would update my review. Photo is showcasing the heatsinks and temps.

Purchased the 2 pack of these SFP+ for a CAT6 run; ant the time there were good reviews and excellent price point. Both ends operated in a climate controlled residential interior, with one in a fan cooled cabinet. They ran fine on my Unifi ecosystem for 9 months until one of the transceivers failed. I should have got more life out of this product and not have to go shopping for a new set this soon!

I have used this in a mokerlink switch with 4 10g sfp+ ports.. worked great. Had to set the ports to 10gig in the web management. connected 3 of the mokerlinks together and also a netgear 8port switch with 2 10gig Ethernet ports. I have used them in Zyxel 12-Port Multi-Gigabit Ethernet Web Managed Switches I have two of the switches connected together at 10gig with sfp+, also a workstation with 10gig card connected into the second sfp+ port. I used on of these in a netgear nighthawk x10 r9000 router in the 10gig sfp+ port and connected it to one of the above zyxel switches in one of its 2.5 gig Ethernet ports. It is what is connecting my router to the LAN side. The zyxel switch reports it connected at 2.5gig. I have not tested performance though. I did not see the increase in performance from workstation to workstation I had hoped for but did see 2x to 2.5x speeds from the Cisco 1gig switches I had been using. went from 60-90 MB/s to 200 MB/s. I did not change out to better cables so maybe seeing some performance issues there. I have a Asustor NAS using a USB 3.1 2.5gig Ethernet adapter connected one of the USB 3.0 ports on it to one of the 2.5 gig ports on one of the the zyxel switches and though it runs a little faster than on the 1gig network its not much more. I am getting maybe 80 to 90 MB/s instead of 50 to 60 MB/s on average. I had been using a LAG with 4 1gig Ethernet ports on NAS to Cisco switch and this seems a bit faster overall. Was never impressed with the LAG. I was surprised this was able to connect at 2.5gig. Its listed 1 or 10gig and I just tried it because. So was happy it worked. So overall I would recommend this if you are using netgear routers with sfp+, mokerlink switches or zyxel switches with sfp+

Seems quality so far from a visual Inspection,unable to test because I do not have something with SFP+ compatability(when I can,I will find a adapter to make it work,SFP+ is not very common though,so it proved quite a challenge to even locate a adapter,though have not purchased it yet,but that will be done some time)

I have a 10 disk Asustor NAS that has two 10GB ports. My main Ethernet switch has two SFP slots and I was able to use the 10G ports on my NAS instead of the other 2.5G ports. The rest of my hose is wired in 2.5G Ethernet so that is the speed limit for any connection to the NAS, but I have multiple computers that work with the NAS, so the throughput from any computer to the NAS is not delayed since the connection from my switch to the NAS is faster.

Broke after a few months, emailed them about warranty, they did not respond. DO NOT BUY IF YOU EXPECT A WARRANTY! The product itself is poor quality and failed very quickly, it doesn't even light up now if you plug it in.

They worked

Acquistato per usarlo con switch Netgear e zyxel. Funziona bene. Non l'ho provato per lunghi periodi: devo dire che si scalda in modo significativo. Per disinserirlo bisogna azionare la linguetta, altrimenti rimane bloccato nello slot (non ho trovato istruzioni, ma ci sono arrivato da solo in poco tempo). L'ho provato solo inserendolo in switch spenti: non ho provato l'inserimento a caldo. Provato con switch da 10Gb e con cavi cat6 da un po' meno di 25m, e non ci sono stati problemi: niente perdita di pacchetti e linea stabile. Immagino che con cavi cat6a o cat7 non possa che andar meglio.

Fonctionne très bien. Dans ce test (W11, appli speedtest), il y en avait 3 sollicités (un dans la carte réseau, 2 autres dans un switch avant de rejoindre la prise RJ45 10Gbits de la box edit: ajout d'un test iPerf

No idea cause it doesn't work properly for TP-Link TX401-also bought from Amazon. The main thing I dislike is the image shown 2x adapter, I can't remember if the (pack of one) is stated when I bought it but I was expecting 2 pieces. I would never buy from these type of dirty tactic product again.
