Resolving the long-standing problem of PON interoperability, Verizon Communications Inc. (NYSE:VZ) successfully validated interoperability of “NG-PON2” at its Technology Center during May. The study focused on ONT provisioning and management and utilized Verizon’s OpenOMCI specification, which outlines the OLT-to-ONT interface and is ranged with the ITU-T Recommendation G.989.3. The company, along with ADTRAN, Cortina Access, Broadcom, Intel and Ericsson/Calix, worked together to advance the OpenOMCI specification that resulted in the successful trial.
Verizon gathered the component vendors and group of system depending on their interoperability experience and expertise with OMCI and with previous generations of PON systems. Since the preliminary NG-PON2 assessment in December 2016, these firms plan to make their software and hardware compliant and are actively putting their efforts in the OpenOMCI specification.
By drawing the tools required to model a multi-wavelength PON, the OpenOMCI specification enhances the count of managed entities and processes that can be used to execute a sepcific service function while disabling vendor-proprietary features and objects that have offered a key obstacle for interoperability measures until now. The OpenOMCI also comprises specific managed firms that, in Verizon’s experience, enhance the stability of PON systems.
Dr. Vincent O’Byrne, the Director of technology at Verizon, reported that the Verizon-directed NG-PON2 interoperability measure is vital, not just for Verizon but for NG-PON2 know-how, and is dependent on lessons known more than the previous 13 years of PON deployment and remarkable associations. They consider this work as eliminating a key roadblock and helping support NG-PON2 deployment.
Along with ONT provisioning and management, the trial focused transmission convergence layer capabilities that enable support of business and residential traffic as well as wireless transport services. These capabilities are innovative to NG-PON2 as against to other PON systems. Representatives of numerous global communications operators fascinated in the NG-PON2 know-how participated in the assessment as virtual observers, which provide them access to the test plans, readouts and specification.
