we have a site has an Cabletron ESX-1380 switch in the 'main' building.
From one of the ports on this switch there is fiber run to a Cabletron SEH 24 into a fiber epim in E1 slot. Then there is a run coming from the 2nd fiber epim in this hub going to the next building to another SEH24 with 2 fiber epims. This building connects to another SEH24 with 2 fiber epims. This connects to the last building with an SEH24.

is this 4 segments or do the EPIMs make it look like one segment? if the former, is this an ethernet spec violation?
of course, it's been 'working' for years

Yeah, this could be considered segmenting since they're all hubs (except for the switch at the end point). But if there's not a lot of traffic being generated then your performance problems should be minimal. As far as violating the ethernet specs, that's ok too since ethernet over fiber is good for up to 2km.

Hope that helps -
