Wavelength routing

Enable new, flexible optical networks with lower total cost of ownership (TCO)

Innovation Leadership - Nokia Wavelength Routing

In 2004, Nokia introduced a new generation of 1830 PSS Wavelength Routing systems, leading the industry in a new generation of Reconfigurable Optical Add / Drop (ROADM) platforms. Compared to WDM terminal and fixed filter systems in common use at the time, Nokia’s 1830 Wavelength Routing systems improved network flexibility, reduced carrier costs, and enabled larger network capacities.

Wavelength Routing Engine – Expanding Possibilities

Nokia’s newest optical networking innovation, the intelligent Wavelength Routing Engine, combines the flexibility of colorless, directionless, contentionless, flexible grid (CDC-F) ROADM with intelligent GMPLS control plane, enabling new, flexible, and power optical layer features and efficiencies

  • Multilayer network planning & optimization
  • L0 / L1 GMPLS restoration
  • Optical layer network optimization
  • Improved network efficiency & utilization
  • Increased network capacity with flexible grid & super channels
  • Improved service velocity
  • Reduced Opex with elimination of manual service re-configurations


Enable new, flexible optical networks with lower total cost of ownership (TCO)

Improve efficiency

  • Increase network capacity with efficient L0 optical restoration, advanced multi-modulation, & flexible grid
  • Eliminate costly, time-consuming manual operations and site visits
  • Increase service velocity by establishing new services in minutes, rather than months

Increase flexibility

  • Move, steer, re-assign wavelengths and services, without manual intervention
  • Optical layer restoration provides automated fault protection for wavelengths
  • Agile, intelligent wavelength routing enables carriers to optimize their network

Expand scalability

  • Advanced modulation formats support up to 250G per wavelength
  • 200G 8QAM modulation is ideal for most regional / LH routes
  • Nokia C+L Ultra-wideband ROADM supports double the capacity per fiber pair
