Global consumer IP traffic has approached 100 Exabytes per month and with the emergence of 5G data, and virtual-reality based gaming, the bandwidth demands placed on the global network infrastructure will continue to grow. As content providers and traditional service providers figure out the economics of scaling their networks while incurring sub-linear costs, the need for an agile fiber optic network with an automated zero-touch philosophy has been accepted as a critical requirement.

To meet the bandwidth and flexibility required for these new services, wavelength Selective Switches (WSS) and reconfigurable optical add-drop multiplexers (ROADMs) that incorporate these WSS’ have taken center stage and become a table-stakes element in today’s agile optical networks.

ROADMs meet all scaling needs that occur in high-bandwidth service deployment, some of which are created by the need for dynamic routing of wavelengths in the long-haul, metro core and edge networks. These include the overwhelming need for lower operational costs, as well as the following:

  • Software-driven, remote provisioning of optical services from the Network Operations Center
  • Greater network efficiency by eliminating stranded bandwidth
  • Elimination of preplanning traffic patterns
  • Shorter optical service delivery cycles
  • Improved inventory control and supply chain management

The ROADM-enabled network helps carriers simplify the deployment and reconfiguration of optical capacity between various optical network segments.

Every fiber optic network being deployed by traditional service providers such as Verizon, AT&T, NTT, Deutsche Telecom, and Telecom Italia, as well as by Web 2.0 players such as Google, Facebook, and Apple uses ROADM –based architectures for operational ease and commercial affordability.

Nistica delivers these capabilities to systems vendors who have architected both the carrier core and access infrastructures and who are well-positioned to fully optimize performance for new service delivery. Nistica enables zero-touch provisioning and wavelength management at cost/performance levels well suited to widespread deployment in the long-haul, metro and data-center interconnect segments.
