IMPAIRMENTS OF BIT-TO-BIT ALTERNATE-POLARIZATION ON NON-LINEAR THRESHOLD, CD AND DGD TOLERANCE OF 43 GB/S ASK AND DPSK FORMATS [FIBRE OPTIC COMMUNICATION]
06 March 2005
Applying bit-to-bit alternate-polarization modulation at 43 Gb/s in ASK/DPSK formats, we found experimentally non-linear threshold benefits up to 4 dB with RZ and 2 dB with NRZ, reduction of DGD tolerance up to 3 ps with RZ formats and a dispersion-tolerance of 20% with DPSK-NRZ.
