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 length distributions. Accurate dimensioning and cost estimation are crucial for optical network planning, especially during early-stage design, network upgrades, and optimization. However, detailed information is often unavailable or too complex to compute. Basic parameters like coverage area and node count, along with statistical insights such as distribution patterns and moments, aid in determining the appropriate modulation schemes, compensation techniques, repeater placement, and in estimating the fiber length. Statistical models also help predict link lengths and shortest path lengths, ensuring efficiency in design. Probability distributions, stochastic processes, and machine learning improve network optimization and fault prediction. Metrics like bit error rate, quality of service, and spectral efficiency can be statistically assessed to enhance data transmission. This paper provides a review on statistical analysis and modeling of optical networks, which supports intelligent optical network management, dimensioning of optical networks, performance prediction, and estimation of important optical network parameters with partial information.<\/jats:p>","DOI":"10.3390\/electronics14152950","type":"journal-article","created":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T10:28:09Z","timestamp":1753352889000},"page":"2950","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Statistical Analysis and Modeling for Optical Networks"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2240-9945","authenticated-orcid":false,"given":"Sudhir K.","family":"Routray","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, CMR University, Bangalore 560043, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2977-3632","authenticated-orcid":false,"given":"Gokhan","family":"Sahin","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Miami University, Oxford, OH 45056, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6744-4381","authenticated-orcid":false,"given":"Jos\u00e9 R.
