Silicon IQ modulator based 80×337.9-Gb/s (42.24 Gbaud) Nyquist-WDM PDM-16QAM transmission over 960 km SSMF with EDFA link

Silicon IQ modulator based 80×337.9-Gb/s Nyquist-WDM transmission was experimentally investigated for 42.24 Gbaud PDM-16QAM. The single channel over 1600 km and Nil-channel transmissions over 960 km standard single-mode fiber (SSMF) with EDFA-only were successfully demonstrated.
