a brief summary of responses up to now:
- there are several vendors making some kind of sx-to-zx gbe converters (they call it gbe extenders), which gives an equivalent of a device with a zx gbic. these vendors include jdsu, luxn, extreme etc.
- two companies were found making gbe optical regenerators - imcnetworks and transmode
- other solution is to try with edfa
mikael: which exact gbic did you use?
i was comparing cisco-reselled gbics and their cwdm gbics seem to be more than 10dB better on power budget... anybody tried this in real life?
thanks again

A transistor protected by a fast-acting fuse will protect the fuse by blowing first.
