High capacity (64 × 43 Gb/s) unrepeatered transmission over 440 km
06 March 2011
We describe a 64 × 43 Gb/s unrepeatered transmission experiment over 440 km of ultra-low loss fiber with third-order Raman pumping. We then compare coherent transmission at 40 Gb/s and 100 Gb/s in unrepeatered conditions.
