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

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.

I slapped this GBIC into my Juniper SRX300 firewall and it worked out of the gate. I was able to get an actual 1Gb throughput when testing file transfers across the SFP.

This SFP adapter seems well made, and, so far, has performed flawlessly providing a backbone network connection from an 8-port Gigabit POE switch. The POE switch this is connected to services eight video security cameras, a mix of 5MP and 4K cameras, all running two streams, (full-res and a sub-stream), at 15fps. This generates a steady stream of network traffic with little room for error. This SFP adapter handles the traffic with no issues, network packets are clean with no drop-outs of corrupt packets. The adapter is housed in a precision all metal case. It fit the SFP socket perfectly with no issues. The RJ45 socket has a locking flange to secure the connecting cable. This is a plug-and-play adapter - No setup is required. Im pleased with the adapter. It was very reasonably priced and is working well.

This is a great value for a copper RJ45 Transceiver running at 1000BASE-T speeds. You cant go wrong with this inexpensive Copper SFP Transceiver.

This copper transceiver has very good construction and high-quality materials are used. It works exactly as its supposed to and provides excellent speeds. Other reviewers have given detailed information as to its performance. Amazon Vine sent this product to me for an honest unbiased review. Would I recommend it? Yes, if you have a need for a copper transceiver, then this is a good option for you.

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.

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.

I am waiting on a new switch with an SFP port to add one copper RJ-45 port to a fiber switch. I did my research and the QSFPNESE had good reviews for building out a 1GB LAN. My network drop will be well within the 100 meters specification in the product description. I am looking forward to installing and testing this transceiver in the switch.

I ordered this for my router. It arrived as described and was recognized as soon as it was plugged in. Im pleased with it and recommend it.

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.
