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

but for gigeth in this case - we need to connect two sites about 200km apart over dark fiber

Check out the 7020 from Transmode <http://www.transmode.se/products/sing_dual.htm>

Btw, my personal best so far is 150km over dark fiber using a extra long haul GBIC, 32dB loss over the fiber and it worked perfectly. Only tested it for 10 minutes, but there were no CRC errors during that time.

+4dB output from the GGBIC, now we have to worry to not look into the laser :)
