Private enterprise networks typically use MPLS, SD-WAN or Carrier Ethernet services. Managed network services are ubiquitous and easy to deploy; however, in some cases it makes sense for an enterprise to consider building a private network with dark fiber. Specifically, enterprises with one or more of the following requirements should consider a Private WAN employing dark fiber:

•    Link speeds greater than 70 Gbps
•    Ultra-low latency requirements
•    Requirements for high-availability network topologies

Peter Fetterolf's TCO Comparison of Private WANs vs Managed Network Services for Enterprises provides an overview of Private WANs and presents the results of a total cost of ownership model comparing a Private WAN with dark fiber to a managed network service (Carrier Ethernet).
