Blog

In today’s digital landscape, network security and reliability are more critical than ever. While public Internet and other shared infrastructure services can expose your business to security risks and unpredictable performance, building and managing a private dark fiber network requires heavy capital investment and specialized skills. So, how do you get the security and reliability you need without the operational burden? There’s a more strategic path forward. 

Enter Zayo Private Networks. Sometimes referred to as Managed Optical Fiber Networks (MOFN), this solution offers a strategic middle ground between shared wavelength services and fully owned dark fiber. By providing the perfect balance between scalability, performance, and privacy, Zayo Private Networks empower your team to focus on building the future of your business rather than managing its underlying network. 

Overcoming Today’s Network Roadblocks 

 Modern enterprises require a diverse network solution stack to meet their unique connectivity challenges. While shared network solutions are suitable for many use cases, they may not always deliver the predictable performance, latency, and privacy needed for critical operations and connections.  

When sensitive data is on the line, relying on shared network services can introduce privacy risks and compliance challenges. Industries like healthcare and finance have strict regulatory requirements that demand private connectivity to keep sensitive data safe. Additionally, data privacy and security are non-negotiable for priority connections, such as those between data centers or from a data center to headquarters.  

This is where Private Networks become a vital part of your technology stack. While many businesses consider dark fiber for maximum control and scalability or shared wavelengths for cost-efficiency, Private Networks offer a powerful middle ground. They deliver the robust performance and security benefits of Dark Fiber without the heavy operational burden of managing it, making them the perfect solution for your most critical connections. 

What are Zayo Private Networks? 

Zayo Private Networks deliver fully dedicated, high-capacity fiber connectivity to organizations that want control over their network’s performance, security, and scalability. Fiber and equipment are provisioned exclusively for your organization and fully managed by Zayo from design to deployment to maintenance, providing maximum bandwidth without the operational burden. 

Zayo Private Networks are available in two distinct offerings, each designed to meet specific business needs: 

  • Private Wavelength Networks (PWNs): Ideal for high-capacity connectivity needs across both long-haul and metro distances. PWNs provide dedicated, high-bandwidth connections that scale easily, making them perfect for data center interconnects, cloud access, and other high-volume traffic applications. 
  • Private Data Networks (PDNs): A more cost-effective solution designed for lower bandwidth metro requirements, leveraging Ethernet connectivity. PDNs offer numerous network architecture opportunities, including full mesh design, providing flexible connectivity that is well-suited for connecting multiple office locations, business parks, or campus environments within a single metro area.

Zayo Private Networks vs. Self-Management 

Deciding between a managed solution and self-management comes down to resource allocation and expertise. With Zayo Private Networks, you can free up your internal teams from the burden of network operations. Customers needing expert management can rely on Zayo to handle full lifecycle operations and incident management. This means you do not have to staff internal teams with optical expertise.  

Relying on Zayo also means significantly lower upfront costs. Self-managing a network often requires higher capital expenditure and introduces ongoing internal staffing costs. Additionally, Zayo acts as your single source for fiber, eliminating the complexity and cost of sourcing and lighting fiber from multiple carriers yourself.
