16×200 Gbps Virtual Carrier Assisted DD Transmission over 80 km with a SiGe BiCMOS 1-to-4 ADC Front-End and 14 GHz of Digitizer Bandwidth

By employing a 112 GSas SiGe BiCMOS 1 to 4 ADC front end, we demonstrate a WDM DD transmission with a net data rate of 200 Gbps per channel over 80 km, which requires only 14 GHz of receivers digitizer bandwidth
