Optical network operators have not broken the so-called "configuration bottlenecks." They have struggled to meet the need for physical transmission and deployment of hardware platforms with unprecedented port density and throughput. But many operators underestimate the complexity of configuring a business in a multi-vendor (or multiple-business) environment.
