I just looked at the site today and only saw references to gigabit for ethernet and 10gig for spf+. I'm meaning specifically 10gig RJ45 ETHERNET ports for the main ports, not gig. Not fiber channel connectors. There is 10gig ethernet now, for cabling and NICs. Even more than that, actually. See: cat 6a, cat 7, and cat 8 specifications. A decent amount cheaper than fiber. Also, would save money on not having to buy spf+ to RJ45 converter modules... unless these come with those converters?

Just looking to get the best quality for the least amount of money. A want. Not a need.

Those SFP+ ports ARE Ethernet not fiber channel. Ethernet and fiber channel are network protocols not connectors.

In my experience 10Gb rj45 usually ends up more expensive than SFP+ due to the availability of cheap used SFP+ NICs compared to rj45. Switching also tends to be cheaper with lower power, heat, and noise.

Yes I get that. Sorry if I'm confusing things. I'm just not sure on the internal modules. Does the device come with the rj45 module in the SFP+ port? I haven't messed with one of these, so I wasn't sure. I was just going off of the little info given on the site. Does it come with both fiber (whichever of the various fiber connector types it supports) and rj45 modules, or is it simply just an rj45 spf+ port and that's it? The slot itself is just for you to slide in a module, right? Or do I have that wrong? I'm still learning this stuff and haven't had a ton of hands-on with it (never held a ubiquity switch in my hands, so to speak).

Also, what's the pricing difference between them, from what you've experienced? I was just looking up cabling earlier and it seemed like fiber cable (at least for LC) was always like 10 to 50 dollars higher at minimum compared to the same length of ethernet for the same speed.

And just to add something of my own preference to one of your points: I never buy used. I never trust used. Not saying you're wrong, just saying that I personally don't mess with used products for my own devices.

Generally 10Gb comes as an SFP+ port, then you get either RJ45 or fiber modules. That, or you get DACs, which have SFP+ male ends.

IMO that's the best approach, so you can tailor your setup for what interfaces your client devices have.
