1000Base-T

Item is not compatible with certain Intel cards, because if you use Intel equipment. It will either not work at all, or if you do happen to get it to work, it will only link at 1gb. Tried a different module, and instantly connected at 10gb.Update- 7/15/2025Even after I had returned the transceiver, 10gtek messaged me about the compatibility issues. They were confident they could fix the compatibility issue. So even tho i had already returned the transceiver and gotten my money back, they asked for my address and mailed me another model to try, FOR FREE!!! And it works perfectly. Get consistent 10gb speeds with over 50ft of ethernet, great transceiver. And my hat off to 10gbtek, I have never had this level of support AFTER a return. They are quick to answer questions, and will not stop helping you until your issue is solved. THANK YOU 10GTEK!!!!! Best customer service I have seen in this day and age.

Installed into our Synology UDM unit; works perfectly, picked up the SFP port immediately and started working at gigabit speeds. For the price, this is an awesome deal.

Works in my UDM Pro Max and getting a full 10Gbe connection to my fiber ONT. While set to 10Gb on the SFP+ port, it still connected to a 1Gbe Ethernet on my old ONT just fine. It does run a bit hot like it says on the package. Heat is typical for these adapters. I added heat sinks like another reviewer and dropped running temps a few deg C. Install was simple, just plugged it in and plugged in an Ethernet cable. Maxes out my 5.3Gbps fiber internet. There are 2 PHY chips these can come with. Both are capable of 10/100m & 1/2.5/5/10G. The AQR113C has more buffer and manages less than 10G connections better using pause frames instead of using blank frames. The ASF-10G2-T only uses AQR113C.

Works great, full 10GbE throughput as expected

This transceiver worked great in another switch I purchased from Amazon 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.

Works well, although like another reviewer mentioned it won't work/negotiate at a lower 100mb speed. Using it in a trendnet 2.5gb switch.

Worked great straight out of box. Purchased 80m variant, handled a ~50m run no sweat.

Worked for about a week before failing during an internet speed test. Verified that it was the SFP+ device by moving to other port, which immediately resolved the issue.Perhaps it was a heat issue as it was located in an enclosed network box, however, an SFP+ adapter from another company has held up without issue in the same environment.Recommend that you look elsewhere for an adapter.
