I have a client with a new location opening.  They negotiated with an ISP for service without IT involvement...  This ISP basically acts as a "hub", requiring the Customer to provide a switch, router, or firewall to go into ISP's data center, which then passes traffic to the customer's location.  
 
I cannot put both of our Firewalls there because the ISP only allows 1 fiber pair out - so no way to achieve redundant connection back to the location.  
 
Any suggestions for a small switch with SFP+ ports that will pass multi-gigabit traffic?
