"without extra gear" like needing new switches cause its a new connector?

It says no extra hardware, not no new hardware. 

If you're maxed out for space already, or renting space by the rack, being able to quadruple your bandwidth for the price of some switches is pretty good.

I think it's a regular sfp module. But I doubt any switch or router support USFP.

I don't know about this claim. If I'm the purchasing manager for my data center and I order 800 optical transceivers at $1600 a piece to replace the 800 transceivers we bought at $950 a piece like three months ago when we opened, I think I'm going to be questioned why we're buying "EXTRA GEAR".

It’s just the next iteration of pluggables. QSFP-DD is 200Gb/lane. OSFP takes that to 1.6Tb but needs twice as many lanes, USFP (this new one) is 4 lanes at 400Gb.

Yep. The double density SFPs are pretty slick and already on the market.

I don't think this "USFP" is compatible with Cisco 2900 series. I will also add it may not be compatible with SFP+ slots. I think this article's author may have oversold this sfp module compatibility with vendors network devices.
