Experimental chacracterisation of the impact of neighbouring modulation-formats on 43 Gb/s P-DPSK over SSMF and LEAF

We report an experimental characterisation examining the impact of differing 50Hz neighbouring modulation formats and bit rates on the performance of 43Gb/s P-DPSK over 1300km of SSMF and LEAF

fibre types. Performance is shown to be robust for hybrid P-DPSK and OOK systems.
