Physical Impairment Based Regenerator Placement and Routing in Translucent Optical Networks

A novel Constraint-Based Routing CBR algorithm taking into account the dominant linear and nonlinear fiber optical transmission impairments has been analyzed. It is shown that CBR and intelligent regenerator placement decrease the blocking probability significantly. In future transparent optical transmission systems automatic wavelength switching will be introduced (Automatically Switched Optical...

Physical Impairments in All-Optical Networks

This white paper proposes an original approach aiming to minimize both CAPEX and OPEX inherent to Electrical Regenerator ER placement. Three linear transmission impairments are considered: ASE Amplified Spontaneous Emission, PMD Polarization Mode Dispersion and Intra-Channel crosstalk ICX. The impact of the gain profile of inline EDFAs is also investigated.

Physical-Layer Considerations for the Realistic Deployment of Impairment-Aware Connection Provisioning

Nowadays, impairment-aware connection provisioning is a hot topic due to the evolution of optical networks to all-optical infrastructures and to the need to maintain or enhance Quality of Service QoS. Most of the research efforts in this field use complex, analytical models of impairments as the basis for the connection...

Performance of MIMO OFDM Systems in Fading Channels With Additive TX and RX Impairments

The performance of OFDM based systems is seriously affected by imperfections in system implementation. To gain a better understanding of the influence of these impairments on the performance of multiple antenna OFDM systems, this paper studies a zero-forcing based MIMO OFDM system with imperfections modeled as additive error sources in...
