Abstract
We demonstrate an all-electronically multiplexed, single-polarization 107-Gbaud quadrature-phase-shift-keyed (QPSK) transmitter and coherent detection using a real-time oscilloscope prototype with 63-GHz electronic bandwidth, sampled at 160 GS/s. Using DFB lasers, we obtain back-to-back implementation penalty of 3 dB and 2400-km transmission.
