Figures & Tables(4)
Fig. 1. (a) PM-kSC-QPSK implementation using the PM-QPSK hardware configuration and (b) joint-decision algorithm.
Fig. 2. Experimental setup for the 500 km PM-kSC-QPSK transmission system at 32 Gbaud. (a) Transmitter, (b) spectrum of the modulated signal, (c) transmission link, and (d) receiver.
Fig. 3. (a) Measured B2B BER for PM-2SC-QPSK, PM-4SC-QPSK, and PM-QPSK at 32 Gbaud (i.e., at the bit rates of 96 Gb/s for PM-2SC-QPSK, 112 Gb/s for PM-4SC-QPSK, and 128 Gb/s for PM-QPSK). (b) Constellations measured back to back at 15.7 dB OSNR. (c) The measured BER after 500 km transmission for PM-QPSK, PM-2SC-QPSK, and PM-4SC-QPSK at 32 Gbaud.
