Cisco cBR-8 Rises up to the DOCSIS 3.1 Challenge at SCTE (part 2)

Guest Blog by Igor Dayen, SP Product and Solutions Marketing

I am excited to continue the discussion that I started in my previous blog on SCTE Cal-Tec expo.

We brought two cBR-8 routers and we used one to run live data through it.   We used Ixia gear to generate video and data traffic. Hence we showed the convergence.

The picture below on the left shows how DOCSIS 3.1 spectrum is being modulated—there are 4096 QAM, while the picture in the middle shows one spectrum for DOCSIS 3.0 and two spectrums for DOCSIS 3.1. Overall, it has been very impressive to see what DOCSIS 3.1 will bring and that we are able to demonstrate DOCSIS 3.1 today.  We offered Read More »

Cisco cBR-8 Rises up to the DOCSIS 3.1 Challenge

Guest Blog by Igor Dayen, SP Product and Solutions Marketing

What do we need to know about New Orleans? It offers great Jazz, and Bourbon Street provides rich insight into New Orleans’ past, but we can’t overlook that it has been home this year to SCTE Cable-Tec Expo. SCTE is the cable telecommunications engineering show of the year. Nearly 10,000 attendees annually seize the opportunity to discover and learn first-hand about the latest in cable telecommunications technology, products and services. For more than 30 years the industry has relied on Cable-Tec Expo to provide the most energizing, technical knowledge exchange of the year.

New Orleans Convention Center opened its doors to the biggest cable show of the year.

The “welcome” signs made it very clear that all attendees were welcome to be here, share their knowledge and learn from the exhibitors.

South Korea’s SK Broadband Improving the User Experience with Cisco cBR-8

Igor-Dayen1-150x150Written By Igor Dayen, SP Product and Solutions Marketing

A year ago, SK Broadband announced the world’s first 10 Gbps Internet service at the 2014 ITU Plenipotentiary Conference. This innovative new service was 100 times faster than existing services, which routinely deliver download speeds of 100 Mbps.

Today SK Broadband continues to break new ground.   Just in time for the SCTE Cable-Tec Expo 2015, SK Broadband announced that they will deploy Cisco’s next-generation converged cable access platform (CCAP) across their national footprint. SK broadband chose Cisco’s cBR-8 as the platform to improve the user experience for their 4.7 M subscribers. In addition to supporting the rollout of multi-gigabit services the Cisco cBR-8 platform is a key part of SK Broadband‘s new network architecture.


As part of Cisco’s Evolved Programmable Network (EPN), the Cisco cBR-8 Read More »

DOCSIS 3.1: Driving Cable to Software Defined Networking

Guest Blog by Igor Dayen, SP Product and Solutions Marketing


Optical transport has been transformed as integrated high-performance Digital Signal Processing has enabled vendors such as Cisco to squeeze more capacity at greater distances than ever before. Advanced modulation techniques and Forward Error Correction are now commonly deployed. Cisco NCS 2000 platform can drive up to 140 channels, ranging up to 200 Gbps each, with the ability to drive 100 Gbps channels to over 4000 km.

Now we’re seeing the same concept appear in the cable space as DOCIS 3.1 sets the stage for new levels of both HFC throughput and capacity optimization. Imagine being able to get an extra 20%-30% of bandwidth out of your existing cable plant without replacing it? DOCIS 3.1 promises to make this a reality.

The Top Five Things That Will Drive Gigabit Consumption

Screen Shot 2015-07-15 at 10.49.10 AMBy Todd McCrum, Director of Product Management, Cisco Cable Access BU

Back in the earliest days of television – before satellites began spraying an instant and national video footprint over the Earth – operators wondered whether it made sense to expand spectral capacity any further. At the time (early 1950s), most markets topped out at three channels. The big question was this: why would we ever need room for more than 12 channels of television?


These days, there’s a similar refrain, with a slight shift in tune. It goes like this: why would we ever need a Gigabit-per-second of bandwidth? Read More »
