I’m getting ready to deploy some Alta gear in my office lab for testing. I searched the forum and didn’t find the answer to my question or on the product pages, so I am asking in the hope it helps others.
Is there a list of supported SFP/SFP+ transceivers and/or DAC cables or is it try different ones until you find one that works?
Here is the one I took and it works perfectly!

Welcome to the community @Pearce !
We have designed the Alta Labs switches to work with most, if not all, SFP modules and DACs. We have tested with most major manufacturers and have yet to find an SFP modules that does not work.
That being said, if someone has found a SFP or DAC that does not work, we would love to hear about it.
Well it had to be me that is having issues with SFP’s.
SFP in question is a 2.5G-SFP-T-MS from EDGE (based in Latvia). Checked with them prior to purchase if it would work in the Alta Labs 24 PoE switch and this was the one they sold me. I have a Netgate 4200 pFsense firewall with 2.5G ports, and as this was replacing a noisy Netgear 48port PoE switch, thought I’d maximise on the SFP’s for the Uplink!
But all I am getting when connecting my Apple Mac is Self Assigned IP address (guess via a Gigabit NUC). But when I connect it to the LAN side of the Netgate as an UpLink, I get no internet connection?
Is there something I should do with the SFP?
Thanks!
Not that I’m aware off. I plugged mine and it worked. Maybe you need to set manually the speed on your pfSense to force the speed on the Alta Labs switch. Since my port in my pfSense is SFP+ (10gig) same as the SFP+ of my 24 ports Alta Switch, I didn’t configure anything. If the speed is different 1gbs, 5gbs or 10gbs I think you should force it.
Might be the SFP not compatible (or not working), as I’ve just tested with a 2.5G Ethernet device and getting Self Assigned IP’s. So going back to supplier of SFP’s.
