When I began covering telecom in 1998, dark fiber initially was used to fuel networks that eventually became today’s internet. At that time an overabundance of fiber builds created what some experts called a fiber glut that did not have enough bandwidth hungry applications to take advantage of these new wires.

But when I think of the role of dark fiber in 2018, the focus will be on serving three domains: fronthaul for wireless operators for 4G densification and upcoming 5G deployments; school districts; and content providers.
