Reduce Ingress and Egress – Simple is Genius

It's a smart idea that doesn't cost a lot more than a regular splitter and also helps reduce ingress. It's called BarrIER technology by Teleste. BarrIER® technology is an innovative solution for reducing ingress/egress that addresses the complete in-home interconnect domain and solves the problem of maintaining adequate C/N levels. Using BarrIER® will reduce the need for manual maintenance work, greatly reduce operational costs, and incrementally increase service reliability and enhance network performance".

Troubleshooting Cable Networks

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

Fresh Tech | Leakage Detection with Brains!

Mia Colabrese2011-11-22T11:11:29-05:00November 22nd, 2011|

I admit that while I help my clients better understand the sources and negative impacts of RF ingress on DOCSIS in a cable plant, I have never found leakage/ingress detection itself particularly high-tech. That was until Daniel Babeux of VGI Solutions gave me a demo of their CPAT Flex Platform. The live demo was straightforward which made it so convincing and intriguing. It consisted of a truck-mount magnetic antenna that connected into a little green box (the brains behind the operation), and a piece of coax cable seemingly chewed upon by a squirrel. The latter connected back into the CATV plant. The awesome part of the demonstration was seeing the location of the antenna appear on Google maps at the Georgia Convention Center in Atlanta, GA. Next when the damaged coax was replaced, the leakage point on the map disappeared along with magnitude of the leakage entering the plant.
