OVERVIEW

OpenROADM is a disaggregated optical networking architecture that enables service providers to create open, scalable, and flexible networks capable of supporting a variety of services and applications. The OpenROADM MSA group defines and promotes Open API models and optical specifications to create an ecosystem that promotes vendor interoperability, reduces vendor lock-in, and lowers the total cost of network ownership.

The OpenROADM MSA group provides a platform for technical experts to exchange knowledge, discuss best practices, and share experiences to ensure the effective implementation of these standards and specifications across the optical networking ecosystem.

OpenROADM YANG Models

The OpenROADM models establish a standard for the interfaces and functionalities of network elements, network management, and service management.

These OpenROADM models promote vendor interoperability and open networking by creating a common management interface for different equipment vendors and SDN controllers.

Service

The Service Yang Model consists of service related data stores, RPCs (Remote Procedure Calls), and notifications.

Network

The Network YANG model provides a generic and vendor independent view of the network.

Device

The Device YANG model provides a framework for a detailed view of the devices (transponders, ROADM, ILAs, etc.) in the network

Open optical and open data plane enables transport interoperation when needed between vendors

  • MW Multi-Wave between ROADMs
  • W between XPDRs
  • Wr between XPDRs and ROADMs

EVOLUTION

OR is not just ROADM interoperation, Topics evolve with carrier needs and technology and include:

  • B400G Interoperation
  • OpenROADM control of single vendor Open Line System (OLS)
  • Brownfield / Greenfield interoperation
  • Remote site over fiber XPDR node interoperation and management
  • Open Pluggables
