40G and Higher, What is Waiting for Us Ahead?

Abstract

This paper describes and analyzes the major technical hurdles that the deployment of 40G line rate transport systems faces in fiber optic telecommunications. A case study is used to study the network readiness for transmission at 40G. Experimental data are used together with a standardized model for verifying if the link is ready to transport 40G. Recommendations are provided following the conclusion of the analysis.
