Abstract:
We experimentally vary the symbol rate of a five channel DWDM IM/DD transmission over 75 km SSMF with a fixed gross data rate of 112 Gb/s per channel and Kramers-Kronig processing in the receiver. The influence of different symbol rates in combination with varying oversampling factors in the DSP of the receiver is studied.
