228 GHz coherent receiver using optical bandwidth interleaving and reception of 214 GBd (856 Gb/s) Pol-Muxed QPSK
16 September 2012
We build an dual-polarization real-time coherent receiver with 228 GHz bandwidth that measures six spectral slices with 24 40 GS/s digitizers and coherently combines them. We receive a 214 GBd pol-muxed QPSK signal over 3200 km transmission with BER below 5e-4
