Your switch has the SFP+ port. The other building's switch does too. What you don't have is 10GbE reaching across that gap without dropping to copper and losing range.
The ATEN 2A-142G slots straight in – hot-pluggable, no reboot needed. Patch in single-mode fiber (LC duplex), and you've got 10GbE running up to 10 km at a nominal 1310 nm wavelength. Two modules in the box, one for each end of the link.
If your network switch supports SFP+ and you're already running SMF cabling, this is the part that makes it work. No guesswork on wavelength, no compatibility roulette. Slot it in, patch the fiber, done
