Cedric Lam on Oct 26 will unveil Go-Long. Google thinks "this new standard can reduce the network operating costs and investment costs." The only information is the press release, 

Go-Long is the company's new generation of optical access networks. Described by Google as a new Time and Wavelength Division Multiplexed Super PON (TWDM Super PON), the company believes that this new standard can reduce the network operating costs and investment costs. The company claims that the technology can do this by extending the transmission distance, which can reduce the number of central offices that need to deploy the optical line termination (OLT), significantly reducing equipment, space and power costs.

In other words, they ain't saying anything until the announcement at BBWF. 

Lam did a Ph.D. in optics under Eli Yablonovitch at UCLA and is a 20-year veteran. whose career began at the old AT&T in New Jersey. He may have discovered the advantage of long reach when he worked on Google Fiber. 

Pressure for long reach goes back at least until when Verizon insisted on 20 miles for GPON. They want to close most of the COs. Their interest has been reduced since they essentially stopped building Fios in 2009. They've filed with DC to eliminate landlines across more than half their territory, essentially everywhere they didn't build Fios. 

Adtran's Kevin Schneider and folks at Nokia-Alcatel have done similar work. TWDM PON is the heart of NG-PON2 if I have it right. 

Fiber isn;t dead, despite the many articles since Google cut back. AT&T is doing 3M lines a year, Liberty probably a million in England and Germany. FT is moving countrywide after doing all of Paris. Telefonica has done most of Spain and now is doing millions in Brazil. I just saw a news story that Algeria Telecom is passing a million homes. 

240M customers have fiber home in China, most in the last four years. It's amazing what a well-managed government company can do. Most of the cities are done but they are buying equipment for millions of more lines every year, for new homes and more rural areas. There's definitely a big demand for fiber.

At BBWF, Google India's Gulzar Azad will also speak. India is now fibering 250,000 villages. The announced topic is "Smart Cities." That usually pr hype for whatever advanced stuff they happening to be deploying, but he'll probably have something interesting to say.

 Geng Lin of Google will then discuss SDN/NFV. Foofle is working closely with AT&T and other telcos on CORD, a surprising but welcome alliance.

 Leading figures from Google to speak at Broadband World Forum
  High-profile figures from Google are showing up in force at this year's Broadband World Forum in Berlin. Visitors to the world's premier event for fixed, fibre and cable operators will have the chance to listen first-hand to Google's vision for the internet.
  First to take to the stage from the multinational technology company is Engineering Director Cedric Lam, whose research covers broadband optical transport and access networks architectures. Lam will be at Broadband World Forum to talk about the company's new Passive Optical Network (PON) technology - Go-Long.
  Go-Long is the company's new generation of optical access networks. Described by Google as a new Time and Wavelength Division Multiplexed Super PON (TWDM Super PON), the company believes that this new standard can reduce the network operating costs and investment costs. The company claims that the technology can do this by extending the transmission distance, which can reduce the number of central offices that need to deploy the optical line termination (OLT), significantly reducing equipment, space and power costs.
  Lam will take to the stage at 2.25pm on Thursday, 26 October, to give a detailed talk on the Go-Long technology and the impact that it will have on the industry.
  The next expert from the technology giant to make an appearance at this year's Broadband World Forum is Gulzar Azad, who is Country Head - Connectivity, India at Google. Azad will be presenting a case study to visitors on how telco investment has helped shape India's Smart City Projects.
  During his talk, Azad will explore how Google is supporting connectivity for the country's populace and the company's involvement in the Smart City Projects. Azad will give an overview on the developing telco industry in India and why it is an exciting time for the country. He also will discuss the possible monetisation models, including the long-term vision for these goals.
  Looking to the future, Azad will give an outline of what the Internet of Things (IoT) means for the future of the country's urban areas, particularly the potential to save energy and water, facilitate disaster relief and the overall improved quality of life.
  Azas holds his Case Study talk at 3pm on Thursday, 26 October.
  The final representative from Google is Geng Lin, who is the Chief Technology Officer, Enterprise Networks and Head of Network Infrastructure, Next Billion Users. Lin will be giving a keynote, entitled Telco Transformation: Spotlight on Virtualising Functions.
  During the talk, Lin will discuss what will modern networks look like and what can SDN do to make them more agile, efficient and reliable. He will also explore Google's vision to deliver Wi-Fi connectivity to emerging markets using vEPC to drive progress and globalisation. And finally, he will close by examining the collaboration between operators and cloud providers to deliver better network performance for users.
  Lin takes to the stage 11.45am on Thursday, 26 October.
KNect365 Portfolio Manager Heather James said: "We are really excited to have one of the biggest names in technology make such a strong showing at this year's Broadband World Forum. The internet of the future will be shaped by the likes of Google, so we're sure that everyone in the fixed, fibre and cable operating industry will want to hear what the company has to say in these significant areas."
