Conventional 40G TDM impacted severely by 50GHz ROADM filter concatenation Volume Deployable 40G Nortel 40G Adaptive Optical Engine The only solution that quadruples the network’s traffic carrying capacity without complex network re-engineering through technology innovation, delivering both economic and operational benefits and best migration path from 10G -> 40G -> 100G. Key advantages: • Innovative plug and play technology deployable over any fiber in a simple network design. • Economic and operational benefits through reduction/ elimination of equipment (Regen, RAMAN, compensators) and through the ability to use existing fiber. • The most elegant migration from 10G ->40G ->100G, reusing technology to similar network architecture (reach and agility characteristics) for all line rates.
