Towards Zero-Touch Optical Multiband Networking with the OCATA Optical Time Domain Digital Twin

Optical in-phase and quadrature (IQ) constellations enclose valuable information regarding the optical elements traversed by the optical signal. Such information can be extracted and exploited by algorithms and models within an optical layer digital twin. In this paper, we focus on their use for accurate quality of transmission (QoT) estimation in multiband optical transmission. Results from simulation show noticeable accuracy.
