I'm looking to see if anybody has found any 5G SFPs that are compatible with the SG500 series switches. I'm looking to upgrade the link between my two but this distance between them precludes using the direct attach stack cables. As 5GBase-T SFPs are becoming more commonplace I was hopeful that somebody would have some experience. I've heard that at least one person has tried the Aquantia AQS-107s (which are 10/5/2.5/1000/100 capable) but did not have success.
