Verizon is building up its multi-gigabit optical broadband work with interop tests for its implementation of the OpenOMCI specification. After the interop test outcomes, Verizon explains OpenOMCI is aligned with the ITU's G.989.3 work.
OpenOMCI is a management specification covering the interaction between optical modems (the Optical Network Terminal, ONT) in the home and the upstream Optical Line Terminal (OLT), and is part of the multi-Gbps NG-PON2 (Next Generation Passive Optical Network 2) standardization effort.
OpenOMCI's role is to automate OLT-ONT interactions under software control – which puts a premium on interoperability. Verizon's partners in its recent tests were ADTRAN, Broadcom, Cortina Access, Ericsson/Calix and Intel.
Gaining access to the spec, the test plans, and the readouts of the Interop test, it was observed by Deutsche Telekom, SK Telecom, and Vodafone. The trial also covered ONT provisioning and management, and features of the transmission convergence layer feature to distinguish business and residential traffic and to support wireless transport services.
Verizon is also testing management objects specific to its own services and wants to make sure vendor-specific managed entities and other objects don't break overall interop.
At the end of June, AT&T announced it will be conducting its own OMCI field trials later this year. Those trials will focus on virtualizing last-mile access network functions for the XGS-PON variant in use in AT&T's network.
