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

Mia Colabrese2013-11-18T09:00:38-05:00November 18th, 2013|

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

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

DOCSIS Modulation Options and Impacts – Part One

Mia Colabrese2022-01-07T11:29:37-05:00October 25th, 2013|

What’s Next for DOCSIS Modulation Options and Impacts This paper is the second in a series titled “What’s Next for DOCSIS:” (Young, 2012), and outlines the anticipated DOCSIS near, medium, and long term next generation (NG) network specifications; identifies and presents high spectral efficiency (SE) modulation options capable of enabling DOCSIS 3.1/NG network specification compliance; identifies the likely modulation technique winner(s) and why; and finally presents NG network operational, test, and troubleshooting challenges facing network installers and repair technicians. SECTION 2 INTRODUCTION – What is Modulation Anyway? Modulation

DOCSIS Pre-Equalization

Mia Colabrese2020-04-04T11:42:09-04:00October 17th, 2013|

DOCSIS Pre-Equalization This paper will first provide a brief primer on DOCSIS to establish a baseline for the document. Next the paper will examine what is DOCSIS pre-equalization. How DOCSIS pre-equalization works and how DOCSIS pre-equalization can be extended. In the greater context of the paper, the reader must consider the implications of the extensions of DOCSIS pre-equalization. In section 5, details will be provided on how DOCSIS pre-equalization can be used to identify plant impairments and locate those impairments to within a few feet. This turns every

DOCSIS 3.1: Begin Preparing Now

Mia Colabrese2013-09-12T14:45:51-04:00September 12th, 2013|

DOCSIS 3.1: Begin Preparing Now Posted on September 11, 2013 by Carl Weinschenk-BTR Experts believe that DOCSIS 3.1 is few years off. The specification has not yet been finalized. After that, test and early customer premise equipment (CPE) and corresponding CMTS and CCAP line cards will be sprinkled through systems. The bottom line is that it will be a long time until DOCSIS 3.1 is an element of everyday cable operations. So preparations should start now. The industry has been down this road before. What seems like a long road, with

Troubleshooting Cable Networks

Mia Colabrese2020-04-02T09:57:28-04:00August 22nd, 2013|

CED Presents an Educational Webcast Troubleshooting Cable Networks - Understanding Ingress Impairments Brady Volpe will be a panelist on: "The two-way nature of cable networks is being increasingly exploited for innovative new features and services, including interactive TV applications, video conferencing, data back up, and wireless backhaul (all in addition to high speed data, VoIP, and Internet TV). Growing reliance on the return path highlights the very common problem of upstream cable ingress interferences. MSO's are planning the deployment of DOCSIS 3.1 technology to offer greater downstream/ upstream

DOCSIS PNM – Something Really Interesting!

Mia Colabrese2021-08-18T09:15:32-04:00August 21st, 2013|

DOCSIS PNM - Get Excited! Awhile back I wrote an article about DOCSIS Proactive Network Maintenance (PNM). Not only did I find this technology fascinating I decided to really get involved with PNM. I will also be speaking at SCTE EXPO on the topic of PNM this year. Topic: DOCSIS Pre-Equalization: Vastly Powerful, Often Undervalued For those of you who have not heard of PNM, here are the highlights. DOCSIS Proactive Network Maintenance (PNM) developed by InGeNeOs™ under Cablelabs®. It is one of the coolest technologies I've been involved
