Dec740 connected to a USW-Pro-8-PoE

[DEC670airp414user]

I am going to replace my Dec670 soon.

thinking about going with the above hardware.     for the 10Gb connectivity part, I am reading all I need is a single UACC-DAC-SFP10-0.5M.  which is listed as certified to work.

can anyone confirm that is all that is needed for me?

Confirm, no. But I'd bet a fair pile of money on it, assuming the length is what you need. Funny, I took a look at pricing (for the cable) and got all sorts of way too expensive results, but the Ubiquity store price was quite reasonable.

what in addition to https://store.ui.com/us/en/category/accessories-modules-fiber/collections/accessories-pro-direct-attach-cables/products/10gbps-direct-attach-cable?variant=uacc-dac-sfp10-1m

would I need for 10G Lan purposes. 

port 9 on the switch which is SPF+  that cable would go to X0 on the OPnsense router.
