This review paper explores statistical methodologies for analyzing network characteristics, dimensioning, parameter estimation, and cost prediction of optical networks, and provides a generalized framework based on the idea of convex areas, and link length and shortest path. One such de-velopment is the introduction of next-generation flexible bandwidth-variable transponders (BVTs), capable of symbol rates up to 140 GBd and a fine modulation rate adaptivity through prob-abilistic shaping (PS). Optical networks serve as the backbone of modern communication, requiring statistical analysis and modeling to optimize performance, reliability, and scalability. The text provides a comprehensive overview of the functional architecture of Optical Transport Networks (OTNs) as defined by ITU-T Recommendations.
