    I bought 4 of these with the 4 port mikrotik 10 gig switch. My computers show connected at 10 gig. My gaming rig has onboard 10 gig and my other two computers have Intel 10 gig NICs installed. I can download from the internet and max my 1 gig connection no problem. When I internally transfer a large group of files, I am only seeing 1 Gbps transfer speeds, not 10 Gbps speeds. I use cat 7 outdoor rated cable and Link up cat 8 field termination plugs and keystones. My cables have been tested. I’ll be ordering a mikrotik 10 Gbps switch with rj-45 built in. Sure it costs over $500 but when you spend 150 or so for the small switch and then almost $100 each for decent transceivers you have spent $500....... the mikrotik 10 Gbps switch with built in rj-45 has 12 ports!

    I ordered the 1.25G to RJ45 for Ubiquiti. These do not work with 100mb devices on a USW Aggregation. Ive never run into anything gigabit that was not backwards compatible but these simply do not work with 100mb devices. They seem fine for gigabit but all the little smart home hubs and what not use 100mb to keep costs down and these dont work with them.

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

    I have a few Mikrotik routers and switches with SFP+ and none of these allow 2.5G or 5G connections with these SFP+ Modules. They work fine at 1G or 10G. Mikrotik said its due to the Ethernet side negotiation not being registered correctly in the ROM so they cant read the DAC information inside of the SFP+ modules ROM. On the Mikrotik side these modules always link at 10G, even when a 1G device is peered. If you need a simple RJ45 10G module then this is good for the price. But do not expect full 2.5G or 5G support with these modules. Also they run hotter then other modules and DACs I use. So consider active cooling applications.

    I have an Aruba S2500-48P switch that has 4 SFP+ interfaces that are noted as only supporting 1gig copper modules in the manual but on a whim i grabbed this thinking if it doesnt work no big deal, but sure enough right out of the package and loaded it into the powered on switch and it picked it up and saw it without issues or additional tricks like enabling unsupported transceivers etc.. Connected to my google router and full10g works perfect on a cat6 cable! Ordered 3 more now. I havent tested jumbo frames/mtu yet but I will update if any issues.

    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.

    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.

    between the Mikrotik S+RJ10, Wiitek, and this..this one was the most stable. tested in a Mikrotik crs328.

    Bought the 10 gig copper transceiver because I couldnt run fiber. These work fine with my Ubiquiti and Mikrotik switches and negotiate 10 gig over CAT6A no problem. They also seem well made. The only downside is they get VERY hot, like hot enough to burn you. This is not that unusual for RJ-45 SFPs, but it is kinda concerning.

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