Please excuse me, I'm new to the environment, but I need some support on what are most likely very simple solutions. I have to connect a 50 micron fiber data line to a port on a Black diamond extreme net 8810 switch with a 8900-10G24x-c 41632b, 24 port, 10GBase-x SFP module. Is a 1000base-SX SFP model#10051H acceptable to make the connection to the port on the switch?
