This is just a first impressions review but so far these modules are working great with a Cisco 3750-X that has a C3K-NM-10G uplink module inserted. I have both 10g SFP slots populated with this SFP connected to a server with an integrated Intel X550-AT2 chipset/phy (using these ports to connect an edge device rather than uplink to another switch/router, it’s just my home lab network). No special iOS configuration is required on the switch. iOS thinks they are real Cisco SFPs and they ID themselves as such. There are no SFP diagnostics/stats available that I can tell but no big deal IMO. I am using two .5m CAT6 (not CAT6a) cables with no issues, obviously this is a short run so I wasn’t expecting any issues there.

I have used several of these in ubiquity equipment and they have worked great. No problems.

Works great with my UDM-Pro and MikroTek 10GB switch. Will buy again.

Im using these SFP plugs to go from my basement (networking room) to my study on my 1Gb system and they work well.

Needed a couple of these to extend network with a downlink between two UniFi switches. Excellent price and received them quick. Link has been up for about 2 weeks now with no problems!

Upgraded to Sonic 10G and existing CAT5e worked (approx 10 meter) with it to bring 10G connection.

Needed these fast for an installation and they worked fine and arrived quickly and much less price vs OEM

Works well and is affordable. I have no complaints with these. Just plug it into switch or NIC and then plug your fiber into it. It also works with Intel NICs and links at 10Gbps.

I purchased this item to use in my UniFi Dream Machine Pro. I inserted the ipoplex SFP+ into the WAN SFP+ slot in the UniFi Dream Machine Pro. The white link light illuminated and the UDM Pro allowed all my devices to connect to the internet. Everything seemed to work until I performed several speed test using different speed test sites. My Verizon Fios 1Gbps connection performed well when downloading but the upload speeds averaged between 5-10Mbps. I tried to manually set the speed on the SFP+ port to 1Gbps but that didn’t resolve the issue. I shutdown then turned on the UDM pro while the SFP+ was still connected but that didn’t resolve the poor upload speeds. I changed the WAN SFP+ port to autonegotiation then I shutdown the UDM Pro, turned on the UDM Pro, conducted speed test and the upload speeds were still averaging 5-12Mbps. I switched back to the 1Gbps WAN port, conducted speed test and my upload speeds were excellent (900Mbps - 922Mbps). I decided to purchase a SFP+ from Ubiquiti to see if the upload speeds on SFP+ WAN port on the UDM Pro will perform as expected. I initiated the return process for the Ipoplex but for now I’ll hold onto the Ipoplex in case the actual issue is the SFP+ WAN port on the UDM Pro. I’ll try the Ubiquiti SFP+ when it arrives. If the upload speed doesn’t improve I’ll know something is wrong with the SFP+ WAN port and not the Ipoplex or Ubiquiti SFP+ transceivers. Until then I have to give this product 1 star but I may have to upgrade it if the SFP+ WAN port is the culprit. The Ubiquiti SFP+ arrived and its working well. My FiOS 1Gb ISP connection download and upload speeds are as expected. Average download speed is 850Mbps and average upload speed is 900Mbps. The Ipoplex SFP+ have been returned. I will only use Ubiquiti SFP+ in my UDM Pro and US-16-XG.

Bought the wrong GBICs for a project, and then took a chance on these because I could get them delivered quickly. So far, theyre working well. Had them live for a month.
