Co-propagation of 6 Tb/s (60* 100Gb/s) DWDM & QKD channels with ~17 dBm aggregated WDM power over 50 km Standard Single Mode Fiber

Abstract

We report the co-propagation, over 50km of SSMF, of the quantum channel (1310nm) of a QKD system with ~17dBm total power of DWDM data channels (1550nm range). A metric to evaluate Co-propagation Efficiency is proposed.
