Our Story

A Network Pushed to the Edge: The global communications industry is undergoing a massive shift propelled by new technologies and skyrocketing bandwidth demands. The need for enhanced performance is being driven by the emergence of new virtual applications and a better broadband experience.

To meet these demands, service providers are pushing both compute and intelligence to the network edge – closer to where data is created and consumed, and the subscriber experience is defined. Traditional network architectures, operational methodologies and business models are not well-suited for this new environment, and traditional industry vendors have been slow to react, protecting investments made in legacy product lines and pursuing business practices that are not aligned with long-term service provider success.

A New Company Architected to Challenge the Status Quo: In 2020, a new global communications company was born to take full advantage of this emerging world. DZS was founded through the vision and leadership of serial industry disruptor and renowned company builder Charlie Vogt, who has systematically assembled a formidable innovation team and engine focused on meeting the demands of the future, developing breakthrough and high-quality solutions, and helping service providers transform their networks and operations to achieve a competitive edge through an integrated suite that includes:

  • 10 Gigabit Passive Optical Networking (10Gig PON)
  • 5G Open RAN transport
  • Software-defined networking
  • Broadband service performance and assurance
  • Environmentally hardened access and optical designs necessary for the emerging network edge

Delivering a Competitive Edge to the Winning Service Providers of Tomorrow: By unifying its global operations and product innovation teams and instilling a pervasive customer-first attitude and agile mindset, DZS is delivering on its commitment to service providers, and the success of this strategy has been undeniable.

Since 2020, DZS has booked over $1 billion in new orders, raised over $100M in new investment, and won over 200 new customers, including some of the largest and most respected carriers in the world. It has also revamped its quality control, support, and services processes and resources to deliver exceptional performance and responsiveness. Today, with over 400 customers, 60,000 systems deployed, and 70 million cloud-connected subscribers globally, DZS has the scope and scale of business that allows it to lead markets in which it competes while remaining agile and responsive to change. DZS’ new products have received numerous industry accolades.

As its customers embrace its EDGE solutions, DZS empowers them to establish their competitive EDGE and enables them to transform from today’s “Service Providers” into tomorrow’s “Experience Providers”.
