TRANSMISSION OF 16.4-BIT/S CAPACITY OVER 2550 KM USING PDM QPSK MODULATION FORMAT AND COHERENT RECEIVER
01 January 2009
A record capacity distance product of 41.8 Petabit/s middotkm is demonstrated. A total of 164 channels are modulated at 100 Gbit/s with PDM-QPSK format, packed with 2 bit/s/Hz information spectral density and recovered by off-line processing in a coherent receiver after 2550 km distance.
