Concept to Deployment: AT&T Pushes Forward with Open ROADM and Optical SDN Implementations

Today, AT&T shared more details around its efforts to scale and deploy OpenROADM technology. For the first time, the company has implemented interoperability using multiple vendors for optical networking. This work will enable its systems to more efficiently manage today’s unprecedented data growth and represents a milestone toward broader industry standardization:


  • Flexible ROADMS (Reconfigurable Optical Add/Drop Multiplexers) and SDN controls will enable bandwidth automation
  • Using the OpenROADM’s Multi Source Agreement, AT&T established optical interoperability between different vendor solutions, common management APIs and a common network model
  • Beginning deployment in Dallas, the goal is to make OpenROADM standard across metro ROADMs first, then eventually all ROADMs


Now past the testing phase, the deployment of this SDN-controlled optical network, along with AT&T’s intelligent algorithms for automation, will strengthen customers’ connectivity so they can continue to do what they need to do at home, and at work and on the go.
