1-Tb/s Dual-Carrier 80-GBaud PDM-16QAM WDM Transmission at 5.2 b/s/Hz over 3200 km
23 September 2012
We demonstrate a 1-Tb/s dual-carrier PDM-16QAM interface (640-Gb/s per subcarrier), created by all-electronic multiplexing to 80-Gbaud. Transmission over 1200 km is achieved using coherent detection, off-line digital signal processing, and soft-decision forward error correction.
