Are you counting $$ or DS0's? > Besides - that doesn't really answer the question what to > do with distances over the 10km. Ehh? It's plug-and play 80 chanels up to some 800km. At 1000km you will need some more clever amp then something from alibababa for $800. You have -3dBm out, need -18dBm on receiver side. If you only need one chanel, waste 3db on connectors, 3db margin and you can have 50km of SMF28. --P > On 28 February 2014 13:06, Peter Lothberg <[email protected]> wrote: > >> We just started planning to upgrade our 10G (and nx10G) links to 40G > >> (on ASR9k).
