I'm going to take a stab and assume that you're actually more interested in finding a longhaul line with GigE on the ends, and not so much how many miles you can get with whatever optics... Absolutely right, I don't care what's in between as long as I have GigE at the end. Other options include using wave (too expensive), or ethernet over MPLS (worth considering although latency may be too high for longer that 1000 miles).
there are solutions of this type. SURFNet line, currently used for test and network research is an example. It is from Amsterdam to Chicago. It is presented as GigE at the ends. So fairly long distance, RTT is 93 msec.Actually it terminate as SONET OC48 that goes too TDM Switch which has GigE interfaces. So there is SONET encapsulation in the middle. In theory we can get upto 2.5Gbps. Line is provided by Teleglobe. End equipements are CISCO, ONS 15454. This don't do any routing. This page may be interesting to browse. http://carol.wins.uva.nl/~delaat/optical/index.html You can probably find different variants of such non standard technology from other carriers. -antony
