In this paper, data plane alternatives for optical performance monitoring are presented as enablers to address the key challenges in disaggregated optical networks. In fact, a key element of the disaggregated networks is optical performance monitoring that is expected to deliver the feedback needed by the control plane to guarantee end-to-end quality of transmission and quality of service. Therefore, we will discuss data plane elements for non-intrusive monitoring agnostic to the modulation format, proposing and analyzing different schemes. Furthermore, we will also review the relevant figures of merit to be delivered to the /SDN/ control, orchestration and management planes and their potential impact on the network performance.
