Application of S-band for Protection in Multi-band Flexible-Grid Optical Networks
Abstract
The core network is experiencing bandwidth capacity constraints as internet traffic grows. As a result, the notion of a Multi-band flexible-grid optical network was established to increase the lifespan of an optical core network. In this paper, we use the C+L band for working traffic transmission and the S-band for protection against failure. Furthermore, we compare the proposed method with the existing ones.
