We just upgraded our internet speed in my office from 100Mbps to 1Gbps. Instead of replacing our old firewall, which supports 1Gbps but doesn't have optical ports, we buy a switch to handle the incoming optical connection and use it for our connection. It worked great and saved us money at the same time!
