When a 27-year old, red-bearded, infinitely curious MIT protégé named Bob Metcalfe joined the research team at Xerox’s legendary Palo Alto Research Center (PARC) in 1972, he had his first encounter with an emerging curiosity: the personal computer. Metcalfe and his team established the first experimental Ethernet specification

SCTE•ISBE Cable-Tec Expo has benefited from two of the sharpest minds in the business, program chairs Jim Blackley (Charter) and Terry Cordova (Altice). Cathy Wilson, publisher of Broadband Library, was lucky enough to sit down with these two engineering professionals and find out their thoughts on the upcoming show and the broadband industry.
By Chris Bastian – The Fall Technical Forum at SCTE•ISBE Cable-Tec Expo 2017 promises to be the technical exchange event of the year. We are very excited to team with CableLabs and NCTA — The Internet & Television Association — to plan and offer this event. Planning started early for this forum: Back in March the Expo program committee, comprising more than 20 executives
By Steven Harris – The access network will require the adoption of scalable new standard architectures leveraging new hardware components and designs. One of the scalable architectures is called “fiber deep”
By Brady S. Volpe – I will cover the concept of virtual CMTS/CCAP, how it pertains to DOCSIS and why this is a disruptive technology in our industry. My name is not Morpheus and I’m not asking you to choose between a blue or red pill here, but let me start off by saying I started out as a hardware guy in the business
By Jeff Finkelstein – In my last article, I discussed briefly the concept of corporate anti-bodies that try to shut down attempts to advance technology which may solve problems that do not exist yet. If we relied solely on those individuals to make the decisions, it is unlikely things would have moved at the incredible rate of change we have seen in many industries, including ours
By David Ririe and Chris Topazi – Having recently completed our initial deployments of DOCSIS 3.1 OFDM on our CCAP platform here at Cox, our team took a few moments to take a deep breath and reflect on what has occurred over the past two years. We thought that sharing our reflections on the successes we have had, the challenges we have faced and overcome, and our view of what the future may hold, would be of interest to those planning to journey down a similar path.
By Patrick Hunter — That’s what I propose to offer you here over the next few installments: a cable perspective from the ground up on what all of that means and how they are interconnected, and most importantly, why any of it really even matters at all.
By Ron Hranac – Optimum cable network downstream performance requires that radio frequency (RF) signal levels be measured and set correctly. RF signal levels affect nearly every part of a cable network’s operation: headend/hub site, optical fiber links, coax distribution, subscriber drops, and customer premises equipment (CPE).
By Stewart Schley – Behind the pop-culture embrace of Citizen’s Band (CB) Radio during the 1970s was a concept of miniaturization: Enthusiasts were enthralled over the ability to transform radio broadcasting from a medium for the masses to a smaller field of play where individualism was the rule and where relatively few individuals might be listening at any time.
By Cathy Wilson – Are you ready for the educational workshops, the newest tech innovations, and networking to the nth degree. The future depends on what you do today” so get ready to join over 10,000 broadband professionals in our industry’s most energizing technology event a/k/a SCTE·ISBE Cable-Tec Expo, on October 17-20th in Denver, Colorado
By Ray Thomas – As test equipment has gotten “smarter” through the addition of automated measurement routines, does the flip side of the coin mean that techs’ understanding of basic electronics theory is being negatively affected? An executive at a large search engine company has speculated in public that the ability to search online for easy answers to life’s questions was dumbing people down.
By H. Mark Bowers – In my last column we examined the importance of scalar testing, definitions of various terms, equipment required, and examined waveforms of actual insertion loss and isolation measurements using a spectrum analyzer and tracking generator.
By Mark Duzban – For the nearly half a century that SCTE — now SCTE•ISBE — has been a part of the cable ecosystem, we’ve been helping the snowballs of cable innovation roll downhill. As the industry’s applied science arm, we’ve been working hard to help the cable industry workforce be better, smarter and — of course — faster when it comes to bringing new services to consumers.
By Reni Gorman – With this feedback in mind we took a critical look at our learning programs. They really were very rich and thorough — should we cut away at the depth that explains the hows and whys? If we do keep the depth we have to make it easier to learn from by making it engaging and interactive, and we have to make sure we also teach how to apply what they’ve learned on the job, and keep from forgetting important technical details that often cause problems downstream.
By The Phantom – Standards bodies anticipate needs and develop standards, and nobody comes to the party. That’s one of the hazards of standards development. Standards are almost always developed by volunteers from companies who are interested in products based on the standard, and those companies spend a lot of money on top engineers working on the standard
