In this paper, we present a theoretical analysis of the noise resulting from cross-phase modulation in an optical WDM transmission system. Analytical approach has been used to evaluate the bit error rate (BER) performance limitation of a WDM transmission system imposed by crosstalk due to cross-phase modulation and the influence of changing channel spacing for various fiber types on the (BER) and...
OXADMs reliability and also survivability of the trunk-line optical network used for data communication. This paper describes the analytical modeling of OXADMs and studies their performance as compared to conventional OXC devices. With two restoration schemes, the OXADM prototype system focuses on providing survivability through restoration against failures by means of linear/multiplex and ring protection...
We present a comprehensive theoretical study of four-wave mixing in optical fiber with exploring four fiber types. The four-wave mixing induced crosstalk noise is described by an expression that is based on NLS equation, and it describes the mutual channel interference optical losses in multi channel optical communications system. The corresponding system of equations has then been numerically integrated,...
Performance analysis is carried out to evaluate the bit error rate (BER) performance limitation of a WDM transmission system imposed by crosstalk due to stimulated Raman scattering. Power penalty evaluated at a BER of 10-9 shows a significant impact of Raman induced crosstalk on the number of wavelengths that can be transmitted. Penalty is higher at higher input power, higher number of channels and...
Performance analysis is carried out to evaluate the bit error rate (BER) performance limitation of a wavelength division multiplexing (WDM) network transmission system imposed by crosstalk due to waveguide grating router (AWG) router. The analysis shows that penalty is higher at higher input power, higher number of wavelengths, larger number of nodes, and higher bit rates, while the BER graphs for...
This paper describes our recent approach toward advanced optical layer networks through the development of optical cross add and drop multiplexing (OXADM). The OXADM node focuses on providing functionally such as transport, multiplexing, routing, supervision, terminating and survivability in optical layer with ring and mesh topologies. OXADM provide survivability through restoration against failures...
