Welcome to a very special episode (er, edition) of Gigabites. This week, EPB lays out its 100-Gig roadmap, schools study their options for gigabit applications, Santa Cruz preps for gigabit wireless and more.
If you thought residential Internet speeds would top out at 1 gigabit per second, or even 10 Gbits/s, get ready to adjust to a new broadband milestone. 100-Gig service isn't far away.
Speaking at Gigabit Cities Live, EPB Fiber Optics executive Colman Keane revealed that 100-Gig speeds are on the company's year-to-year roadmap. That's not hyperbole, and it's not a vague promise of exponential speed increases. EPB created one of the first gigabit cities in the country in Chattanooga and has roughly 6,000 gigabit customers today. It's also among the first companies testing next-generation PON technology and deploying 10-Gig services to both business and residential subscribers. Keane believes the demand for greater broadband capacity will only continue to grow, and EPB plans to be ready when it does. (See Gigabites: EPB Signs First 10-Gig Customer.)
Keane was also among those at Gigabit Cities Live to share new insights into why gigabit and multi-gigabit speeds are so important. As Keane explained it, speed was used as a proxy for latency when EPB first installed gigabit broadband to power communications in its smart grid network. Total capacity was less important than the ability to ensure fast response times.
Today, latency continues to be important, but so too is the capacity for running high-bandwidth applications. For example, students in a Chattanooga high school lab are relying on gigabit broadband to learn from scientists at the University of Southern California, and to manipulate a 4K microscope 1,800 miles away.

According to US Ignite COO Joe Kochan, other schools are interested in emulating the Chattanooga/USC model, and professors in other scientific disciplines are looking at how to share their equipment and expertise in similar ways.
Kochan also talked about the future ability to offer services like telemedicine in schools, which could give students necessary healthcare consultation and treatment while also keeping them on site on school grounds.
Broadband that solves education and healthcare problems? It's no wonder EPB is planning for the 100-Gig future.
Independent ISP Cruzio is promising to bring gigabit wireless service to Santa Cruz later this year by connecting existing fiber to millimeter wave radios provided by Siklu Communications Ltd. According to officials, the new service will be ready for residents this summer.
Cox Communications Inc. has extended its Gigablast gigabit service to customers in Middle Georgia. With plans to offer residential gigabit service across all of its markets by the end of this year, Cox has already deployed Gigablast in parts of Phoenix; Orange County, Calif.; Las Vegas; Baton Rouge; and Omaha.
Windstream Communications Inc. (Nasdaq: WIN) is also on a roll. The telco launched gigabit service this week to roughly 35,000 residential and business customers in parts of Nebraska, Kentucky, Texas and North Carolina.
BendBroadband doesn't offer gigabit service yet, but the company plans to start a gigabit trial in Oregon later this year using DOCSIS 3.1 technology.

It is highly unlikely that ordinary residential and small business customers will even come close to utilizing 1 Gig at any time in the foreseeable future, with any forseeable applications. 100 Gig is the stuff of data centers, metro and backbone, and will remain so for a long time.
40 Gig PON (4*10 Gig) is more an aspiration than a reality. Yes, all the big players have done field trials, with prototype equipment. None are shipping product. The technology is too expensive. More to the point, component and module vendors see a tiny market, and all their resources are focused on 100/200/400 Gig data center interconnect and metro.
100 Gig PON (4*25 Gig) is a few lab experiments, and some talk in FSAN and IEEE 802.3.
Data rate as a proxy for latency ceases to have benefit at somewhere between 1 and 10 Gig. At those rates, propagation delay, rather than serialization delay, is the dominant source of latency.
Ok. There's engineering reality and there is marketing reality. This is the latter.
