DOCSIS Return | Dirty Fiber Optic Connectors

2012-09-24T03:14:16-04:00September 24th, 2012|

An often overlooked, but easy to resolve RF impairment are loose and/or dirty fiber optic connectors.  This issue often manifests itself as an increased noise floor when viewed on a spectrum analyzer.  The key to determining the difference between regular ingress and fiber connector noise is that the noise created by a loose or dirty fiber connector does not stop at the diplex filter roll-off frequency (typically 42 MHz in North America and 65 MHz Europe).  The image below shows a perfect example of this type of impairment:

DOCSIS Security Illegal Wiretapping and Eavesdropping

2012-09-04T10:00:57-04:00September 4th, 2012|

Wiretapping has Evolved Before electronic eavesdropping there was just wiretapping.  When you think of wiretapping you may think of a guy in a box truck or apartment eating donuts with pizza listening in on endlessly boring phone conversations waiting to hear that one "Eureka" moment of important information.  The movie Casino comes to mind too.  The scene where Sam and Nicky have their wives talk on the phone first and then take the conversation over in timed intervals so that they can speak. So what is wiretapping?  It is

This address is programmed into a writable memory address of the hardware in the cable modem, and is associated with a

2020-08-06T11:33:35-04:00July 23rd, 2012|

While checking out the booths at ANGA we came across a company by the name of Vu+.  What caught my eye was Linux written in big letters on the side of the booth.  Anything Linux will usually get me to walk into a booth.  We met with two associates one from Vu+, Victor Heo and one from Marusys, Rose Chang who gave us a tour of their companies products and introduced us to HbbTV.
