Two years ago, we reported that “Verizon has completed a field trial of NG-PON2 fiber-to-the-premises technology that could provide the infrastructure for download speeds up to 10 Gbps for residential and business customers.”
This past January, Verizon completed its first interoperability trial of NG-PON2 technology at its Verizon Labs location in Waltham, MA. During the trial, Verizon demonstrated that equipment from different vendors on each end of a single fiber—one on the service provider’s endpoint and that the customer premises—can deliver service without any end-user impact.
In an October 16th press release in advance of the Broadband Forum’s Access Summit, Verizon said NG-PON2 represent a paradigm shift in the access space and a more certain path towards long-term success.
“Technologies such as NG-PON2 present exciting new opportunities for vendors, such as delivering residential and business services on multiple wavelengths over the same fiber,” said Vincent O’Byrne, Director of Technology at Verizon.
“Not only does NG-PON2 parse business and residential customer traffic to isolate and resolve potential problems in the network, it can also scale to achieve speeds of 40 Gbps and above,” O’Byrne added.

At the Broadband Forum’s Access Summit, The Verizon executive will address how the fiber access space is constantly evolving, with emerging PON technology providing solutions to some of the issues around cost and reliability during the Broadband World Forum, at the Messe Berlin on Tuesday, Oct. 24th.
Verizon has been an active participant in driving awareness about how NG-PON2 can work in a real-world carrier environment. The company completed NG-PON2 interoperability with five vendors for its OpenOMCI (ONT Management and Control Interface) spec, bringing it one step closer toward achieving interoperable NG PON systems.
The mega telco plans to offer it’s own OpenOMCI specification , which define the optical line terminal (OLT)-to-optical network terminal (ONT) interface, to the larger telecom industry.
Note 1. OpenOMCI specification was developed and is owned by Verizon, rathr than a formal standards/spec writing body like the ITU-T or Optical Internetworking Forum (OIF). Is this the new way of producing specs (like “5G” used in trials)?
Bernd Hesse, Chair of the Broadband Access Summit and Senior Director Technology Development at Calix, said:
“We will be exploring NG-PON2 in depth and the use cases that underpin the decisions to deploy them. I look forward to the debate, hearing from the experts in the industry and welcoming the community to these new Forum events.”
AT&T Expands G.fast & FTTH Deployments:
In sharp contrast to Verizon’s decision NOT to deploy G.fast, AT&T has announced expansion of its G.fast service for multi-dwelling units (MDUs) and its fiber-to-the-home network (AT&T Fiber).
The mega telco will extend its all-fiber network in two markets — Biloxi-Gulfport, MS and Savannah, GA. AT&T will also be offering its hybrid fiber-coax service for MDUs in 22 metropolitan markets.
The AT&T G.fast deployments will use “fiber runs to the telecom closet on the property, and individual coax runs to each apartment unit,” an anonymous AT&T spokesperson said to Telecompetitor.
Residents of properties served will also be able to obtain DIRECTV service without installing a dish at their individual units. Instead, the video service will be delivered over D2 Advantage, which the AT&T spokesperson described as “a centrally wired satellite dish that is shared among residents in the property.”
AT&T announced eight metro areas where G.fast can be deployed immediately, including Boston, Denver, Minneapolis, New York City, Philadelphia, Phoenix, Seattle and Tampa. In 14 other markets, consumers in target MDUs can order service now for deployment in “the near future,” the company said.
AT&T is one of multiple carriers that are looking at G.fast as part of their broadband strategy. The technology can support considerably higher speeds than DSL or fiber-to-the-neighborhood (FTTN) services – and although bandwidth is lower than it might be for a fiber-to-the-home deployment, the cost is considerably less.
The news that AT&T is deploying G.fast is not surprising, as the company already has conducted a trial of the service in Minneapolis and executives have indicated deployment plans. At this year’s Open Network Summit (ONS), AT&T’s Tom Anschutz told an audience that G.fast would improve the speed and signal quality of data transmission on older, low grade twisted pair, which is used in many MDUs and in condominium complexes (where this author lives). He hinted that market segment would be a focus area for AT&T.
AT&T is extending the reach of its fiber network:
AT&T claims to have the largest fiber network in its 21-state home broadband footprint, reaching more than 5.5 million residential and commercial locations across the 57 markets after adding over 1.5 million sites since January 1st. Plans call for extending service availability to another 1.5 million locations by year’s end, boosting the total to 7 million.
Of those 5.5 million homes and businesses now reached by AT&T Fiber, the mega telco said it has signed up more than 2 million broadband subscribers. The company did not, however, break out how many of those subs are new ones, as opposed to DSL customers who have been upgraded to the new FTTH network.
However, the mega telco ranks #1 on Vertical Systems U.S. Fiber Lit Buildings (Fiber to commercial buildings) leaderboard:
