For the record, 1000BASE-LX 1310nm 10km and 20km rated optics did not work
across this span. Based on loss measurements, this was not due to optical
budget. This may be due to the cutoff wavelength of this fiber being 1360nm.
1000BASE-LX 1310nm 40km rated optics worked (with a 10dB attenuator.)
1000BASE-ZX 1550nm 80km rated optics worked (with a 10dB attenuator.)
Hope that helps someone in the future. If anyone has any comments, I would
be interested to hear (either pm or public.)
