Abstract

The benefits of amplets as banded amplification solutions in metro networks are quantified. In current networks that employ WDM as point-to-point fiber relief among pairs of super-hubs in synchronous optical network (SONET) rings, banded solutions based on erbium-doped waveguide amplifiers (EDWAs) provide a strong techno-economic value proposition. As WDM penetrates into the metro core with the introduction of WDM ring/mesh connectivity and eventually into the edge, this specific value proposition weakens. We present a physical transport performance model as well as simplified economic analysis on specific network simulation scenarios that represent the above actual metro network architecture evolution to support the value proposition.
