The growth of bandwidth that delivers business and consumer services has never been greater.  The emergence of high-definition television (HDTV), YouTube, business Ethernet, and peer-to-peer applications together with the need for global connectivity and presence has placed new constraints on carrier networks.

To meet the bandwidth and flexibility required for these new services, reconfigurable optical add-drop multiplexers (ROADMs) have taken center stage and become a critical element in today’s agile optical networks.

ROADMs meet many needs that occur in high-bandwidth service deployment, some of which are created by the need for dynamic routing of wavelengths in the 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.

Carriers regard existing core ROADMS as expensive solutions because of their high first costs and additional amplification requirements. In essence, core ROADMs are only cost-justifiable for 10% of applications in the service provider metro network. To support high-growth, bandwidth-intensive applications carriers need simpler, lower-cost intelligent optical add-drop throughout their metro networks. Operators now deploy multiple wavelengths at all central offices for high-bandwidth services. They are very interested in ROADM alternatives or extensions that give them a cost-effective option for meeting their needs in their edge networks. Operators will soon deploy multiple wavelengths at all central offices for high-bandwidth services.

Nistica is the first company to develop a new family of intelligent, low-cost subsystems, to automate service providers’ metro core and edge installations.

The ROADM-enabled metro network helps carriers simplify the deployment and reconfiguration of optical capacity between their rapidly growing broadband access networks and high-powered optical core networks.  In short, they meet the demands of today’s agile optical networks.

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 distributed metro environment.

The flexibility of Nistica’s ROADM subsystems adds value to a variety of optical platforms, ranging from low-cost replacement of Fixed Optical Add-Drop Multiplexers to low-cost extension of Core ROADMs and MSPPs.

In short, nodes with up to 100% add/drop capability in smaller Central Offices are becoming a top priority for service providers, and this part of the network will be a locus of growth for some time to come. Nistica enables this growth, supporting carrier forecasts for high traffic and high-margin service delivery at the optical edge.

Nistica brings to this demanding network realm the performance benefits of the core ROADM at up to 85% reduction in first costs and operating expense. The company’s innovation, technical flexibility, carrier-class robustness and cost/performance will fill a critical gap in the evolution of optical service platforms and optical carrier networks.
