On the possibility of compensating material dispersion in three-layer optical fibres in the wavelength range below 1.3 μm

Abstract

To date, various connection rerouting methods for connection-oriented mobile networks have been proposed. The previous methods, however, are limited to specific topologies or environments. In this paper, we propose the connection-information-based rerouting widely applicable to various connection-oriented mobile networks. This method requires neither a specific topology nor a complex connection, enables fast rerouting, provides appropriate route optimality, and can be extended easily.

About the parametric synthesis of an optical fiber using a dispersion characteristic

“…This value corresponds to the optical fiber with m = 1.5, for which the radial dependence of the concentration of germanium dioxide in the core is defined as follows: In fiber-optic communication systems with wavelength-division multiplexing (WDM) optical fibers must have small values of the dispersion coefficient in a wide range of wavelengths. To solve this problem we use waveguides with depressed cladding [2]. We will consider the fibers , in which the concentration of germanium oxide GeO 2 in the core (radius a) decreases according to (6).…”

“…Those optical fibers must have a complex refractive index profile (RIP) [2]. The rough calculation of dispersion as sum of material dispersion and waveguide dispersion brings to errors.…”
