PMD Mitigation for 42 x 43 Gb/s DPSK (NRZ and RZ) by Distributed Polarisation Scrambling over 4820 km long NZDSF Fibre
16 September 2007
Simultaneous mitigation of 8ps mean DGD at 43Gb/s is demonstrated over 42 channels by use of 5 polarisation scramblers distributed over 4820km NZDSF straight line and UFEC with system margin. DPSK-NRZ and -RZ modulation performance is compared.
