We have a 200mbps commerical fiber connection and we are trying to connect 5 laptops and a wifi router.  The location is remote and we don't have an abundance of support, many of us are not from a networking background but know enough to be dangerous.  We are trying to figure out what piece of equipment (switch / router or both) we need to complete the service connection and get us operational.  The fiber is terminated to an LC connector, we have an LC-LC cable and a SFP module ready to go.  We have a single IP and we are looking for a DHCP server capability to support 8 devices.  Any and all assistance is greatly appreciated.
