Conference paper

Influence of lasers with non-white frequency noise on the design of coherent optical links

We experimentally demonstrate for a 28 Gbaud 64-QAM metro link that the LO frequency noise causes timing impairment. Results show the existence of LO frequency noise spectrum regimes where different design criteria apply.
