Abstract

Optical networks, characterized by their use of optical fibers as a transmission medium, constitute the fundamental infrastructure employed by network operators today to deliver services to users. As total network capacity is one of the key factors influencing optical network performance, it is important to comprehend its limitations and have the capability to estimate its value. In this context, we revisit the concepts of capacity from various aspects, encompassing channel capacity, link capacity, and network capacity, thus providing an integrated view of the problem. Furthermore, we review the fundamental concepts underpinning optical networks, along with the basic physical phenomena present in optical fiber transmission. Additionally, we also provide capacity estimations using mainly formulations found in the literature and compare our estimations with select published experimental results.
