calix stock 230Testing in a major telco lab. The new Sckipio chip allows daisy-chaining 24 port boards for up to 96 ports. (Other approaches require an external vectoring controller.) Calix has wasted no time developing a 48 port DSLAM, showing this week at BBWF.

The new Calix/Sckipio DSLAM also supports "up to 2 gigabits," although it best to think of that as 1.5 gigabits. The cDTA allows near instantaneous switching of an individual subscriber's bandwidth from downstream to upstream, allowing much faster upstream. 

“Calix has been the leader in coming to market with Gfast breakthroughs, enabled by our [SDN] AXOS platform," is the kind of statement I usually ignore because I have no way to verify it. There are probably as many claims of best SDN as there are makers of SDN software. I can confirm that AXOS looks very practical after the presentations at the Calix press event. 

The stock was clobbered because of a bad result last quarter. A cost overrun in a turnkey deployment hurt earnings. There are many things going right for the company: Verizon is working with their NGPON2, their rural customers are spending more, and they have more deployments of G.fast than anyone else.

They have a very strong technical team and CEO Carl Russo is the best salesman in the business. 

 

Calix Extends Gfast Leadership; Leverages AXOS to Introduce Industry’s First 48-Port, Amendment 3 Solutions

 

Next generation solutions being trialed in a Tier 1 network today dramatically transform Gfast deployment economics in MDUs by tripling subscriber density and doubling broadband speeds

 

BERLIN – October 23, 2017 – Calix, Inc. (NYSE: CALX), the world leader in Subscriber Driven Intelligent Access, today announced the latest addition to its industry-leading AXOS Gfastfamily with the introduction of the groundbreaking E3-48F Gfast Remote Node (sealed DPU) and E5-48F Gfast Node, the industry’s first 48-port, Amendment 3 solutions. Introducing these next generation Gfast solutions and beginning trials in a Tier 1 lab at this pace is only possible due to the speed of development that AXOS enables through its anyPHY™ hardware abstracted architecture. The AXOS E3-48F and E5-48F redefine both the performance and economics of Gfast deployment, especially in larger MDUs where old wiring has historically meant a sub-par subscriber experience. These latest Calix AXOS Gfast systems allow service providers to take advantage of a core tenet of Gfast Amendment 3, 212 MHz support, which doubles broadband speedsover copper and, when deployed with Calix cDTA and bonding technologies, delivers symmetrical speeds of up to 2 Gbps to subscribers. Industry-leading port densities that are three times that of competitive solutions dramatically reduce costs per port, while vectoring for up to 96 ports without the need for an external VCP further enhance scalability and deployment economics.

“The gigabit experience is fast becoming table stakes for service providers to capture and retain broadband-savvy subscribers. As such, service providers must find a way to deliver this experience, no matter where a subscriber is located," said Teresa Mastrangelo, founder and principal analyst at Broadbandtrends. "With the introduction of the new Calix solutions that support Gfast Amendment 3, service providers now have a more streamlined and economical approach to meeting these demands for subscribers in MDU locations and differentiating themselves through a consistent service offering across copper and fiber.”

With more people living in MDUs relative to other housing environments, MDUs represent a significant opportunity for service providers, as well as a significant challenge. There is a wide variety of variables when bringing broadband service to MDUs from wiring to building size to environmental differences, but Calix AXOS Gfast solutions provide a way for service providers to standardize on one technology for every scenario. Through AXOS, service providers can take advantage of an unparalleled time-to-market advantage through accelerated system installation and Always On capabilities that simplify operations and eliminate maintenance windows. By dramatically reducing the length of the prolonged and costly deployment cycle needed for fiber, today’s AXOS Gfast installations can be done in a matter of days, sometimes even hours.

“Calix has been the leader in coming to market with Gfast breakthroughs, enabled by our AXOS platform, from the first Gfast-bonded solution through the groundbreaking cDTA functionality which was demonstrated at last year's Broadband World Forum, and now the industry's first 48-port solution with Amendment 3 capabilities," said Shane Eleniak, Calix vice president of systems products. "Each of these advancements has been focused on enabling service providers to deliver an unmatched broadband experience to all subscribers, even those living in older buildings fed by copper. With the E3-48F and E5-48F, we are taking a big step forward in allowing our customers to have a competitive advantage in every deployment scenario. We are proud that global service providers recognized Calix Gfast solutions as the best in the world and the world’s only software defined access platform, AXOS, will ensure that we remain at the top."

See the new AXOS E3-48F and E5-48F on display both this week at Broadband World Forum in Berlin in Booth #A119 and next week at Calix ConneXions in Las Vegas.

I’m still working through remarkable presentations from the Broadband Forum events. Michael Weissman, Bernd Hesse and team did a remarkable job choosing the speakers. http://bit.ly/BBFBASE

Deutsche Telecom: 35b Supervectoring Delayed to 2019 http://bit.ly/35blater
Broadcom is now over 3 years late. DT briefed German reporters after their financial call and revealed 35b was now delayed until 2019. 35b should deliver 200+ meg downloads 500-600 meters, a crucial tool for DT, which is losing share to cable. Cable now covers about 70% of Germany and is expanding. DT now only offers 50-100 megabit DSL while cable is often 400 megabits, going to a gigabit. 

The problem is software; the hardware is shipping and supposedly will work. DT says 35b is not ready to turn on. Broadcom in 2015 said 35b was in "production" in the press release below. Alcatel in early 2016 said to expect complete systems very soon. "35g is very similar to 17a so there should be little delay."

Broadcom's problems are leading major telcos and vendors to have a plan B, using Sckipio G.fast. DT itself is planning extensive G.fast deployments in 2019, mostly in apartment buildings. http://bit.ly/35blater

Gigabit 100 Meters - Unless the Wires are Lousy http://bit.ly/gflousy
Speeds are fine, "Unless there's a line problem." I've been reporting for three years that ~10% of lines have problems. In the chart by Rami Verbin of Sckipio, he finds G.fast goes ~130 meters on good lines. Poor lines have about half the reach. 

His chart roughly matches the reports from Swisscom, Belgacom, and England for both G.fast & vectored DSL. The 10% with problems can cause the majority of the line-related complaints to support. The angry customers drive up cost.

Rami's solution to reach the gigabit is bonding, supported on the Sckipio chips. Verbin made some additional points:

  • 4 gigabits is possible by bonding two decent 2 gigabit lines.
  • Even in a service from remote cabinets, ~25% are close enough to get a full gigabit."
  • cDTA and iDTA are practical ways to deliver much higher upstream by switching some bandwidth from downstream to upstream only when needed.
  • 35B will probably be similar but Deutsche Telecom doesn't expect to deploy until 2019. http://bit.ly/gflousy

AT&T Wants Coax 2-5 Gigabit G.fast. Very Soon. http://bit.ly/ATTCoax
AT&T faces intense competition from cable, talking about 10 gigabits in both directions. (Cable will only be 1 gig down, ~100 meg up, until ~2021.) AT&T wants something to brag about as well.

AT&T gained millions of lines of coax as part of the DirecTV deal. Alcatel and Huawei are leading the development of G.mgfast. That uses 424 MHz, full duplex, to achieve ~2.5 gigabits in both directions. The reach on telco twisted pair is only about 30 meters. On coax, those speeds can probably extend far enough to service most apartment buildings. Using 848 MHz, speeds can reach 5 gigabits. The ITU standards group has been aiming for 2019-2020 for G.mgfast, too slow for AT&T's marketers. David Titus wants a high-speed standard for coax "early in 2018." He believes that is "doable."http://bit.ly/ATTCoax
