Verizon says it has proven interoperability based on its OpenOMCI specification, a step that makes OMCI and ONT vendor selection more flexible and cost effective.
The service provider, which is in the process of upgrading from BPON to NG-PON2, focused the trial on optical network termination (ONT) management and provisioning. The OpenOMCI specification defines the interface for optical line terminal (OLT) to ONT; it's aligned with the ITU-T Recommendation G.989.3, according to
Verizon, in conjunction with partners ADTRAN, Broadcom, Cortina Access, Ericsson/Calix and Intel, developed the OpenOMCI specification, which the operator tested at its Technology Center in Waltham, Mass., in May. Results became publicly available today.
"I don't want to sound overly bombastic, but it's a very important step forward. It creates flexibility for selecting the vendor for the OMCI and ONT separately and it allows Verizon to move forward at a decent cost for the deployment," said Denis Khotimsky, distinguished member of the technical staff and Verizon's lead engineer for the trial, in an interview.
The Verizon OpenOMCI specification is designed to optimize the number of managed entities and ways operators can use to deploy a service function. It proactively prevents vendors from including proprietary objects and features, a move designed to reduce costs and time to market, he said.
Verizon wanted to avoid using the word "optional" in the standard since it can be misinterpreted and create proprietary hurdles, said Khotimsky.
"Sometimes if an implementer sees the word 'optional' in the specification, the implementer may interpret this word as 'it's my decision to either support this feature or not support this feature.' That gives rise to non-interoperable implementations," he said. "If there are two solutions for one problem… then one vendor can choose one solution and another vendor can choose another solution, and all of a sudden the implementations become non-interoperable. The second principle of the OpenOMCI specification is that in no case should the word 'optional' be interpreted as at the vendor discretion."
Other operators interested in the specification include
SK Telekom and
Vodafone, which observed the trial virtually. Verizon is
sharing the OpenOMCI specification, hoping it's included in appropriate standards.
