Multi-rate vs. OTN: Comparing approaches to build scalable, cost-effective 100Gb/s networks

Abstract

In this work we compare network designs based on pure WDM equipments at both 10Gb/s and 100Gb/s line rate, to a pure 100Gb/s design where electrical OTN switches are integrated with WDM equipment. OTN switches introduction grants savings in terms of CAPEX and OPEX, and optimizes network utilization.
