100G DWDM transport systems: Driving the technologies and deployment

This paper introduces a carrier´s activity on 100G DWDM systems; driving the technologies to open the market, contributing to fair and timely deployment to carrier´s field. First, we review carriers´ requirements for 100G based DWDM systems, and indicate some of the key functions needed for coherent Digital Signal Processors (DSPs). A proof-of-concept DSP is fabricated and subjected to a technical feasibility study of its functions and real-time performance. This reasonably power efficient device will advance the maturity of 100G coherent DWDM systems. We also introduce interoperability testing result on 100G coherent optics. Multiple-sourced interoperable solution could accelerate the deployment of 100G DWDM systems.
