Summary of the FCC Workshop: Future Fiber Architectures and Local Deployment Choices The workshop was comprised of two panel sessions featuring an excellent mix of academic, industry, analysts and community networking people. Video of the panels and the panelists presentation slides are all available at: The range of speakers and their presentations leaves me optimistic that the FCC “gets it” – they are listening to good people with divergent views and no longer define “broadband” as 250 kbps. I have selected one slide from each presentation and added a short comment (in red). I have not listened to the presentations – the comments are what occurred to me when I selected the slide. Selecting the slides to include was difficult – I left out some good ones, and would recommend your looking at the rest and listening to the presentations if you are interested in broadband policy. This is an experiment in how to cover/summarize a conference. For another excellent summary see this post by Goeff Daily in which he extracts noteworthy quotes from the presentations.post by Goeff Daily

Dynamic Spectrum Management: The Path to Gbps DSLs/ Future of Copper John M. Cioffi, Prof Emeritus, Stanford U, Chairman and CEO, ASSIA Inc.

How Fast is Copper? 10 Gbase-T is 2.5 Gbps/pair –at 100m on category 6 twisted pair 11/19/09 FCC 3 150Mbps – 500Mbps DSLs demonstrated –100m on category 3 twisted pair Ubiquitous100Mbps to 1 Gbps DSLs? –Dynamic Spectrum Management (DSM) Soon, cheap, and energy efficient And, a lot of signal processing LP: Don’t ignore the potential of copper

FCC Broadband Workshop on Future Fiber Architectures and Local Deployment Choices David Reed, EVP & Chief Strategy Officer, Cable Television Laboratories, Inc.

Use of Cable Spectrum  Same amount of RF spectrum delivered to each home passed  Spectrum may be reused for interactive services by sub- dividing into service groups *Includes upstream Number of 6 MHz Channels per Household Service Group Size** Spectral Reuse Total Delivered Channels per 20,000 HHP hub Percentage of Delivered Bandwidth Linear Content101 20, % SDV % VoD4 1, % Broadband*4 1, % % **Representative values only, wide variation in practice due to cable system specifics LP: there is a lot of cable bandwidth, and it can be reallocated as customer demand and services change.

Hybrid Fiber Wireless Reshapes the Future of Communications David P. Reed, MIT Communications Futures Program, MIT Media Laboratory, Viral Communications Research Group

11/19/09© Copyright 2009 David P. Reed7 Air power – the 21 st century tussle Most wireless will be very localized, very dense (homes, buildings, campuses) Wireless supported by fiber – fiber transport is utility underlying wireless, not single termination. Strategy for fiber is to capture wireless support market. LP: wireless will connect us within 100 meters, fiber for backhaul – interaction in the local community is critical.

FTTH Technology and Standards Roadmap David Russell, Solutions Marketing Director, Calix

Next Generation FTTH Standards 10G GPON (NGPON1) –987.1/987.2 completed in September Gbps downstream (1577 nm) 2.5 and 10 Gbps upstream (1270 nm) Coexists with on the same fiber with 2.5 GPON –Full standard by June 2010, deployments in 2012 Beyond 10G GPON (NGPON2) –Thinking/talking /technology presentation stage –WDM PON is a candidate technology –Does not require ODN compatibility with today’s 2.5 GPON 10G EPON (XEPON) 802.3av –Ratified in September Gbps downstream (1577 nm) 1 Gbps (1310 nm) and 10 Gbps upstream (1270 nm) –Deployments likely in 2010 and 2011 LP: FTTH standards are in place for now – when am I likely to see 10 Gbps at my home?

Fiber networks already prove in over copper for new builds & are closing the gap vs. overbuilds $ Deployment Cost 2000 FTTH Costs Homes Passed + Homes Connected F = $/HP = $/HC 1, ,300 2, Since 2004, the cost to deploy FTTH has dropped about 45% It now costs network providers about $1,450 to bring optical solutions direct to your home. Due to the adoption of new technical innovations we expect deployment costs to continue to decline to $1,300 by Since 2004, the cost to deploy FTTH has dropped about 45% It now costs network providers about $1,450 to bring optical solutions direct to your home. Due to the adoption of new technical innovations we expect deployment costs to continue to decline to $1,300 by Source: Fiber to the Home Council LP: Verizon (see Lynch presentation) confirms that installation and operating costs are falling.

Services cannot be predicted Network design and technologies need to offer flexible and scalable platform for tomorrows services Why build OSP that can only support FTTH ? –B2B –Wireless backhaul –CO Consolidation NG-PON2 will be deployed within 5-10 years, Change to OSP needed –(European deployments mostly P2P) LP: for PON see

If I could, I would be paying much more than in other markets (see Felton presentation). Is what is good for Verizon good for the US?

Local Governments and Fiber to the Home 57 municipal FTTP networks in the US Range of architectures, vendors, business models, technology choices Key is local decision-making and flexibility –in technology model –in business model (sometimes limited by anti- competitive state law) Emphasis on expanse and multiplicity of services, bandwidth, and affordability 17 LP: Local governments do a good job (see Nulty, Felton presntations) and there are many experiments under way. How can we encourage such experimentation in the face of resistance by the incumbents?
