Design of low-margin optical networks
- Pointurier Y.
We review margins used in optical networks and review a formerly proposed margin taxonomy. For each category of margins, we review techniques that the network designer can use, in order to increase the capacity of optical networks, extend their life, decrease deployment cost (CAPEX) or total cost of ownership over their life duration. Both green field (new network deployments) and brown field techniques (used after initial network deployment) are discussed. The technology needed to leverage the margins and achieve the aforementioned gains are also reviewed, along with the associated challenges.View Original Article
