The Cable Network, Immersive Experiences and Lightfields

By Andrew Ip and Dhananjay Lal – The SCTE Cable-Tec Expo demonstration was a powerful example of how cable industry partners came together to showcase a novel application that would need an entire ecosystem.

HFC and 5G Backhaul — Two New Friends

By John Chapman – There is more good news regarding specific improvements to DOCSIS for small cell backhaul. The first is the DOCSIS Time Protocol (DTP).

The Cable Operator’s Road to 10G

By Tom Cloonan and David Grubb – it should be clear that operators will have many technologies and many options from which to pick as they migrate forward towards 10G operation in the future.

A Preview of 10G Enabling Technologies

By Kinney Bacon – Cable operators need to start thinking about how they will distribute the 10 Gbps signal through the home network once 10 Gbps technology is available and offered as a service.

The GAP

By Ed Dylag – So, as you can see, the GAP specification will not only provide deployment streamlining through standardization and modularization, but also opens up a whole new group of opportunities to operators.

Preparing for Upstream Upgrades with Legacy CPE

By Dave Wachob – Changing consumer and business needs have greatly increased the need for additional upstream capacity, especially due to recent outbreaks of COVID-19. With the introduction and enhanced capabilities of DOCSIS 3.1, remotely configuring the modems to operate in the mid- (5 MHz to 85 MHz) or high-split (5 MHz to 204 MHz) return bands is relatively straightforward.

COVID-19 Learnings

By Jeff Finkelstein – Generationally each version of DOCSIS has given us between 8-10 years. I expect that DOCSIS 3.1 will last in many cases until 2030 or so. DOCSIS 4.0 and its possible follow-on releases have the potential to last to 2040 or a bit longer.

Managing the Bandwidth Surge

By John Ulm – Normally, day-time usage is much lower than peak evening hours, but that changed dramatically for the upstream. It hits its peak late morning and then stays there until almost midnight.

Connectivity and COVID-19

By Bill McFarland – Like other industries, carriers saw significant financial impact. New technologies can help in at least two areas: the costs of customer support and additional revenue from new services.

Protecting Our Network Heroes

Jim Walsh – The current pandemic will eventually be in our rearview mirror, but the consensus is that life will not revert to exactly what we previously knew. Working from home will continue at least part time for many employees based on statements from many major corporations.
