Long distance SFP module for M580 Hot Standby

[JerryBartlemay]

I have a customer need for a separation of two M580 hot standby CPUs of at least 13 miles (21 km).  Our standard single mode fiber SFP module has a range of 15 km, or 9.3 miles.  Has anyone tested any high power SFP modules for single mode fiber that have a distance rating of 30-40 km?  

While SFP modules are built around a standard, that doesn't mean they are all compatible with all hardware, and so need to be tested.
