DOCSIS Pre-Equalization Video

Mia Colabrese2022-01-07T09:01:46-05:00February 5th, 2014|

DOCSIS Pre-Equalization Video This DOCSIS pre-equalization video will cover some important items. DOCSIS Pre-Equalization is something that every cable provider should know about. With a simple line of code on the CMTS, you can achieve an immediate and significant improvement in your upstream signal levels. Pretty important stuff, so we’ve tapped Brady Volpe, one of the foremost experts on the subject. On Tuesday, February 4th at 4:00 PM EST, Brady will be chatting live on this page with Scott Helms, ZCorum’s VP of Technology, about the benefits of pre-equalization.

PNM and HFC Readiness for DOCSIS 3.1 – CCTA 2014

Mia Colabrese2021-12-15T10:11:40-05:00February 3rd, 2014|

Daniel Howard, CTO of the Society of Cable Telecommunications Engineers (SCTE) presented at this years CCTA on "HFC Readiness for DOCSIS 3.1". Daniel had a presentation that couldn't be beet and held the attention of the audience. Key topics he covered were the rapid growth of Internet traffic, cable operator's desire to extend the life of coax cable at least another 20 years, PNM and the realization that 4096-QAM is a reality in the cable plant.

CED – Proactive Network Maintenance

Mia Colabrese2014-01-30T10:36:45-05:00January 30th, 2014|

Proactive Network Maintenance ZCorum debuts DOCSIS upstream tester ZCorum has introduced a new tool that analyzes DOCSIS pre-equalization data, which cable operators can use to identify upstream impairments. The company’s Pre-Equalization Analyzer uses technology from Nimble This to analyze the pre-equalization data from cable modems. Nimble This is a collaboration of software developers with The Volpe Firm, headed by Brady Volpe. The new ZCorum tester can not only identify upstream impairments, but also determine the location of the impairment and the severity of the impairment. This allows operators

DOCSIS 3.1: Modulation Options and Impacts – Part Two

Mia Colabrese2023-02-17T13:02:40-05:00January 22nd, 2014|

What’s Next for DOCSIS 3.1 Modulation Options and Impacts DOCSIS 3.1 modulation - Many wonder how today’s networks will support high order modulations such as 4096-QAM. There are two technologies in the DOCSIS 3.1 standard that will enable this without requiring changes to existing outside plant. The first is Orthogonal Frequency Division Multiplexing (OFDM). This is a complex word for taking many small QAM channels, like 25 kHz instead of 6 MHz, and placing them very close together. OFDM also has dynamic properties. If you have a block

Next Gen Spectrum Analyzer SCTE EXPO 2013 - Fresh Tech At this years SCTE EXPO equipment and software venders were showing they knew they need to keep an eye to the future. Already featured (Rohde & Schwarz, VeEX, Cisco and Nimble-This) JDSU showed a nifty next gen spectrum analyzer. Now it's not available to ship until Q2 2014 but it's still worth a look. VSE-1100 Video Spectrum Expert JDSU states it's "the industry’s first converged digital spectrum video analyzer and noise-troubleshooting platform designed for the challenges of the

DOCSIS Burst Demod SCTE EXPO 2013 - Fresh Tech There were some new and exciting things at this years SCTE. There was a good drum line at the opening event but also there were new products and innovative ideas (Cisco and PNM). In test equipment this year at the SCTE EXPO Rohde and Schwarz, JDSU and VeEx all had some new things on display. None of the items are currently shipping (with the exception of R&S who used existing equipment) but it does show that test equipment vendors are

Cisco’s New CMTS and Nodes – SCTE EXPO 2013 – Fresh Tech

Mia Colabrese2013-11-06T09:00:16-05:00November 6th, 2013|

Cisco's New CMTS and Nodes SCTE EXPO 2013 - Fresh Tech Feeling special having been invited into the "whisper suit" at CISCO's booth to get a first look at Cisco's new CMTS and Node. No one was permitted to take photo's so my description will have to be enough. Cisco has gotten completely out of their normal box for their new CMTS. It is much smaller than the traditional 10k. It's also much quieter than the 10k. It also looks cool. Those are the small things... What really

Cable App for iPad and Android SCTE Cable-Tec EXPO 2013 At this years SCTE EXPO I again walked the show floor looking for innovative and cool technology that equipment vendors were showing. This years Expo had some great new products, one I'll be highlighting in this article, which is a cable app for iPad and Android devices by 4Cable.tv. Now to be totally honest I actually never made it to all the booths. I ran out of time! Which is a good and a bad thing. It means
