Customers like the performance of the switch. They say it works perfectly well with Ubiquiti UDM-Pro and provides 2 RJ45 WAN ports. Some mention that it runs hot and works in a pinch, but beware of the 30m limit. It works as expected on a Cisco switch and flawlessly with CAT6a backbone. Some say that the Gtek transceivers work quite well and allow you to create one or two extra. Some customers also say that it works as a DAC replacement and works straight out of the box.

Works with a Netgear MS510TX Switch

Works with a Netgear MS510TX Switch
I bought this for a Netgear MS510TX multgig switch. It has one SPF+ port (slot 10). I plugged in the module to the switch and then plugged into my Alienware Aurora R13's 2.5Gbps built in motherboard port. I am getting 125Mbps download and 20Mbps up. If I connect to one of the MS510TX's 2.5GBps port I get 1400Mbps download and 44Mbps up. Clearly an issue with this module or its not Netgear compatible as it claims.I tried setting the NIC to 1Gbps Full Duplex, and 2.5Gbps Full duplex instead of Auto and it makes no difference. I have a 10Gbps PCI-e NIC coming in the mail tomorrow. If having the 10GBps Module connected to a 10GBps NIC makes a difference I'll update the review. Using Windows 11 fully patched as of Jun 2022. Same Cat8 Ethernet Cable used for both speed tests.Update to 5 stars from 1 star: I just swapped it so my Netgear RAX120's 5Gig port talks to the 10g SPF+ module and my PC talkes to the MS510TX's built in 10G ethernet port and I now get my normal 1400Mbps down. So apparently the Aurora R13's built in 2.5Gbps NIC had an issue talking to the 10Gbps SPF+ Module.
