New approach of fiber optic telecommunication lines upgrade by dense dispersion managed solitons

A well-known dense dispersion managed solitons (DDMS) technique is applied to increase bandwidth of metropolitan area network fiber optic links. This technique requires an installation of optical cables with dispersion compensating fibers (DCFs), which leads to high costs for upgrading of installed fiber optic links. To become the DDMS more applicable, we propose to place dispersion compensating module or optical cable delivery lengths with DCFs in optical fiber closures. Here results of numerical simulations of optical pulse propagation estimation in fiber optic link with DCFs in optical closures are represented.
