Deployment strategies for 40G/100G coherent networks: trade-offs and impacts

Presented by

Jean-Sébastien Tassé, Product Line Manager, EXFO

About this talk

EMEA Edition When deploying 40G/100G technologies, service providers must choose whether the new wavelengths will be deployed over an existing network and traffic (brownfield deployments) or over unused, new fibers (greenfield deployments). This choice usually depends on the context, type of network (metro, long-haul, etc.), capacity requirements and so forth. But more importantly, each approach has its pros and cons, and specific set of challenges. This webinar explores the tradeoffs of greenfield and brownfield next-generation architectures, the impairments these approaches give rise to as well as the associated costs. More specifically, this webinar will discuss three impairments (polarization mode dispersion, nonlinear effects and interchannel crosstalk), their relative prevalence in greenfield vs brownfield deployments, and their impact on bit error rate. Finally, a way to analyze these impairments non-intrusively will be presented.
