Just want to announce for the history record that last week we 
did OC768/STM256 NY/USA-Lulea/SE using routers with integrated optics
all the way. Longest hopp was SeaGirt to Blabjerg at some 7500km using
RX-DPSK modulation on the underwather cable. 

Interface facing submarine cable in Denmark when link came up..

POS0/5/0/0 is up, line protocol is up
