H!Fiber.com SFP+10GBASE-T Transceiver Copper RJ45 Module Compatible for Juniper Networks EX-SFP-10GE-T, Reach 30m, for Data Center, Switch, Router

It works great in my Netgear R9000, but I think it was forged in the fires of Mordor because this thing runs HOT. Runs so hot you recoil your hand if you touch it.Now, it’s 15% the price of the official Netgear 10GbE module and it’s been running over a week with no issues so I’m going to keep it and recommend it to others.

It's 1.25G, 2.5G, 5T, 10GBase-T compatible but not 1GBase-T so make sure you have one of these speed.It doesn't work on a 2x1G Internet offer for example as 1.25G cannot run at 1G (for example if you have an UDM SE and want to use WAN2 for the second 1G line).

Successfully tested with my UDM Pro with a 2.5 GbE internet, and my local 10 GbE local network.

Can use with UBNT Switch.

I bought a 10 pack of Auto-Negotiation SFP to RJ45 Module, 10/100/1000BASE-T Ethernet Transceiver and low and behold it's typical untested junk they're shoveling on the market. They work fine as 1gbit, but they do not advertise the capabilities to the switch for 10 or 100, and the do not auto-negotiate.To get them to work in 1gb mode I must force the switch port side to 1gb, and full duplex. There is quite literally ZERO auto-negotiate capabilities on these SFP's. They refuse to work at 10 or 100mbit even though they advertise them as such. Even trying to set the switch port to 10 or 100 it refuses as the SFP does not indicate that's a capability.I think they just slapped the 10/100/1000 label on their 1000 only SFP's, charged more and called it good. H!Fiber just another company pushing trash on the market.
