As a network operator, you need greater capacity to meet ever-increasing bandwidth demands. And you need greater agility and programmability to rapidly respond to an increasingly dynamic network environment. The Cisco Network Convergence System delivers all this and more by harnessing nLight ROADM, silicon, and multilayer control technologies. The Cisco NCS Multi-Rate dense wave division multiplexing (DWDM) Line Card uses nLight Silicon to combine multimodulation capability with soft-decision forward error correction to flexibly trade off transmission rate versus reach, with exceptional optical performance.
