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

PNM - Proactive Network Maintenance CableLabs Booth - SCTE EXPO 2013 - Fresh Tech The PNM demonstration in the CableLabs booth was very popular at this years SCTE EXPO as was Armstrong and Comcast. Both very impressive. Comcast's demonstration of their PNM Scout Flux solution by the SCTE Pavilion was most impressive. It won the BTR 4.5 diamond award in 2012, but it is not for sale. Now Comcast has been working on their solution for over five (5) years with a team of smart people working on

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

Mia Colabrese2013-11-11T09:00:21-05:00November 11th, 2013|

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

First-Gen DOCSIS 3.1 Test Solution – SCTE EXPO 2013 – Fresh Tech

Mia Colabrese2023-12-13T11:03:56-05:00November 4th, 2013|

Rohde & Schwarz Demonstrated a First-Gen DOCSIS 3.1 Test Solution Fresh Tech - SCTE Cable-Tec EXPO 2013 Rohde and Schwarz had a popular demo at this years SCTE EXPO and not only was it popular it was innovative since it was the only DOCSIS 3.1 demo on the show floor. Using off-the-shelf equipment R&S demonstrated a first-gen DOCSIS 3.1 test solution. This is a precursor to their eventual delivery of real-time equipment. The demonstration consisted of a signal generator (AFQ100B + SMBV) and signal analyzers (FSW wide-band vector

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
