About to run some network connections between two buildings. Both buildings will have their own ISP but I need to expose network resources from each building to the other one (ie. users from either building get their own wifi/internet in the other building), so it will all be managed by one gateway one unifi setup with dual WAN. I think I've got all that part down, but I've never run any fiber before so want to make sure I have the hardware setup.

Current hardware all connected with cat6 copper:

• Building 1 Gateway: USG-Pro-4 (will be replaced if/when Ubiquiti releases a new gateway)
  • Has two 1G WAN SFP ports
  • Has ISP coming into WAN1 RJ45
• Building 1 Switch: US-16-150w
  • Has two 1G LAN SFP ports
  • Also have a bunch of USW-Flex-Mini's hanging off this, but not really relevant
• Building 2 Switch: USW-Lite-8-POE
  • Has no SFP ports
• Building 1 Wifi:
  • 2 x U6-Pro
  • 1 x U6-LR
• Building 2 Wifi:
  • 2 x UAP-AC-LR

So I'd like to run out of the Building 1 Switch SFP over fiber to Building 2 to get LAN over there. And run Building 2 ISP over fiber to Building 1 Gateway WAN2 SFP. 1G network speeds are all the hardware supports anyway, not too worried at this time about ever seeing anything faster.

So I think the hardware I'd need is:

• 2 x UACC-OM-SM-1G-S-2 (two pack) BiDi SFP Single Mode Modules
• 2 x UACC-AE Media Converters for Building 2 to convert back to copper
• 1 x OS2 Single Mode Duplex Fiber Cable with LC/UPC ends
  • This gives me one bidirectional strand for WAN and one bidirectional strand for switches?

Is there anything I'm overlooking here? Run is not long, under 100 feet, so I take it multi-mode fiber would work too, but not seeing a big cost difference and single mode bidi means less strands needed (and can easily get pre-terminated duplex fiber cable that allows splitting of the connector). But is there any other gotchas here that I'm not thinking about? Or any of this hardware that wouldn't be compatible?
