We talk a lot about network innovation on the virtualized side of the network, but what about the backbone of the network? Deploying fiber deep pushes better cable service closer to the customer, enhances scalability, and addresses concerns about aging copper being a bottleneck to network innovation. Cox Communication's Dr. Eugene Dai and EXFO's Sophie Legault spoke with TIA NOW from Cable-Tec Expo 2017 about the drive towards deep fiber, what impedes deployment, what deep fiber means for five nines reliability, and how service assurance will change as the network evolves.
