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 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.

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 have a UDM-Pro and use one of the SFP ports for failover if (when...) the Xfinity service goes down. Ive been using a Ubiquiti SFP adapter for about 2 years, but didnt have a backup. This SFP adapter looks nearly identical - the case is indistinguishable, although the exposed circuit board is clearly a little different. This QSFPNESE SFP adapter was recognized instantly by the UDM-Pro. The UniFi software shows the vendor as OEM and the part number as GLC-T-QS (see image). It connects at 1,000 FDX, but I dont have the ability to test beyond my LTE cell phone uplink, which seems to max out at 80Mbps with the poor signal level in the house. This item is a little less expensive than the Ubiquiti adapter, and it also doesnt have Ubiquitis high shipping costs!

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.

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 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.

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.

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.

This worked immediately when I plugged it into my Mikrotik hEX S router, giving me an additional usable ethernet port. Checked the interface, and it was auto-negotiated at 1Gbps (max speed on the SFP port of the hEX S). Ran a speed test plugged into this adapter and compared it with plugging directly into one of the existing ethernet ports, and there was no noticeable difference. I have gigabit cable internet, and got a little over 800Mbps download speeds in both tests, which is expected for my setup considering everything else on the network at the time the test was performed.

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.
