QSFPNESE 1000BASE-T SFP RJ45 Copper Transceiver up to 100m Over Cat 5 Cable,Compatible with Cisco GLC-T/SFP-GE-T, Meraki, Mikrotik, Ubiquiti, Netgear,TP-Link and Other Open switches

SFP-T transceiver works as expected providing upto tested 1Gbps speeds over CAT 5e cable. This is in use on a Juniper SRX 3xx device and no losses of packets under test conditions. Fits well into SFP cage with proper locking to cage. Cable connections are also tight allowing solid connections. For systems that can query the SFP there are some diagnostics that can be reviewed. While likely being unsupported by most hardware vendors this good backup alternative.

A very easy upgrade to my aging home server. It was a 2 minute installation once I got to the back of the rack. It replaced a Cisco 100 and upon reboot loaded its drivers and worked seamlessly.

Ive had a QSFPTEK Gigabit SFP RJ45 transceiver in my Ubiquiti EdgeRouter 4 since 2020. Its been problem-free, but Ive had no spare, which bothered me both for outright failure replacement and for debugging. I shut the EdgeRouter down and powered it off, swapped this one of the QSFPTEK that was in it, powered the EdgeRouter 4 back up. As soon as the EdgeRouter 4 was back up, this transceiver was immediately recognized and data started flowing at full-duplex, gigabit speed (its a bridge between two VLANs with different ISPs feeding them). It was identified by the EdgeRouter 4 with a vendor of OEM and a part ID of GLC-T-QS -- the same part ID shown on the label. There were no issues with fit, finish, materials, or workmanship. It seems to be the equal of the QSFPTEK tranceiver it replaced, which has been a fine product. Im leaving this one in place since I want to know if there are any issue before I declare that its the primary and the older one is now the spare. If anything comes up in the near term, Ill try to remember to update this review.

Starting to build out my homelab and grabbed this. It plugs and plays without issue and does exactly what it should. May start getting NIC cards to handle these so I can just swap them out when I get >2 G to the house.

I ordered this as I have a cable modem with dual Ethernet outputs, and my Ubiquity UDM-Pro has SFP ports on it. Installing it was a breeze, and then configuring my UDM-Pro to use the SFP slot was also very easy. I ran a speed test of my connection using the standard ethernet port, then switched the cable over to the SFP adapter, and ran the speed test again. I have a 400mb/s connection, and there was no difference in speed between the two ports. I cant test if it truly has 1GB/s speed, but I am confident that it does.

I tested this on my Dream Machine Pro and had to set the port to 1000M because of a bug in the software, but this worked fine. Good option if you need an extra RJ45 port in a pinch.

I have a Cisco 3850 and older switches to use this transceiver on. All of my devices worked just fine with this and didnt need to force compatibility in the config. It just worked out of the box and didnt exhibit any issues from my testing. Worked fine for uplinks and testing on the equipment I needed to work on.

Needed a RJ45 Transceiver for a project and for testing equipment. This works and is an outstanding value! Works exactly as advertised. Tested on a few Extreme Networks switches.

The 1000BASE-T SFP RJ45 Copper Transceiver worked out of the box. I havent had the opportunity to measure if the bandwidth is actually met, but I dont have many devices that require or support it. Word of caution, make sure you get the correct type of device. You may not pick the right one if youre not really sure.

This is one of those items that either works or ot doesnt. This was instantly recognized on my Aruba switch and provides me with an additional port as I dont currently need an optical connection. Its exactly what it says it is.
