[TriLUG] Above Gigabit Network

[Alan Sterger via TriLUG]

Hi Listers,

I have residential Google (GFiber) Gigabit Internet with a powered 
GFiber box (blue light).  Using one of the two Google Wifi (hockey puck) 
routers with a Netgear GS116Ev2 plugged in providing wired Ethernet.

I've ordered a new computer that does 2.5 Gb.  This will be my first non 
10/100/1000 network device.  Thinking about upgrading the switch.  
Should I look at an switch that has SFP input?  Is it as easy as 
plugging RJ-45 into a SFP adapter which plugs into the switch?

For me, Ethernet above 10/100/1000 is uncharted territory.

Thanks for any intel you can shed.
