Impairment-Constraint-Based Routing in Ultralong-Haul Optical Networks With 2R Regeneration

This letter presents a novel impairment-constraint-based routing scheme in a network with 2R regeneration. A wide variety of physical layer impairments, linear and nonlinear, have been considered and appropriate modeling has been developed to reflect their interplay with the 2R functionality and to...

Zusammenfassung:This letter presents a novel impairment-constraint-based routing scheme in a network with 2R regeneration. A wide variety of physical layer impairments, linear and nonlinear, have been considered and appropriate modeling has been developed to reflect their interplay with the 2R functionality and to assess the overall system performance. Using this approach, the optimum routing paths are identified and the network blocking probability is evaluated as a function of regeneration efficiency and transmission performance engineering
