ROADM (Reconfigurable optical add-drop multiplexer)

PTN

Introduction

The network is connecting an ever increasing number of devices. People want more—faster Internet speeds, higher bandwidth applications and better quality video. As the world becomes increasingly interlinked and traffic demands surge at an unpredictable growth rate, there is a compelling business case to continue to evolve the metro towards a scalable, adaptive packet-based infrastructure that moves through an agile all-optical long-haul network.

In this volatile and very competitive environment, what if there was one platform that could meet all functionality requirements for both the metro and long-haul sections of the network, simplifying the design to drive down costs in both the capital and operating infrastructure?

The product Series consolidates layers of networking functions and platforms, addressing a wide variety of applications with a reduced number of nodes. The same platform can be employed for wireless backhaul, data centre connectivity, or business services delivery, can act as an optical transit node with multi-way branching and is leading the market with 40G/100G wavelength transport.

Feature

  • Adjusts to site-specific requirements with three shelf variants, all operating on the same software load with interchangeable circuit packs
  • Supports coherent 40G and 100G interfaces to maximize return on investment by delivering up to 10 times more traffic capacity on the existing network
  • Electronically compensates for dispersion, eliminating the need for fixed compensators and associated amplifiers, while also simplifying engineering of the network
  • Delivers a complete suite of integrated Wavelength-Selective Switch (WSS)-based ROADMs for flexible per wavelength add/drop/ passthrough per wavelength and per wavelength switching
  • Supports OTN mapping, multiplexing, and transport for standards-based OTN management and networking
  • Provides aggregation/statistical multiplexing on MEF-certified packet interfaces allowing the efficient delivery of packet services with stringent SLAs
  • Provides full OAM capabilities and the same carrier-grade capabilities across Layers 0, 1 and 2, while preserving the operational values of circuit-based networks and a familiar paradigm
