DOCSIS Return | Dirty Fiber Optic Connectors

Mia Colabrese2012-09-24T03:14:16-04:00September 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:

EPON, EPoC, DPoE, RFoG, DOCSIS®-Beyond the Alphabet Soup Operators’ services are migrating from traditional to IP delivery, which is driving a need for an evolution in the access network. Technology changes to the access network are a multi-year deployment cycle, so operators are investigating and trialing different technologies for next generation delivery. This session will explore the pros and cons, technical and financial trade-offs, and possible hybrid approaches of these various technologies.

Calculating... Calculating... DOCSIS Codeword Errors - You will likely see them DOCSIS correctable codeword errors and uncorrectable codeword errors are available as a metric in most cable operator monitoring tools and Operations Support Systems (OSS). The monitoring tools and OSS generally provide data and dashboards for users to monitor overall network health and then identify a problem when it occurs. Metrics like codeword errors are extracted directly from DOCSIS CMTSs using Simple Network Management Protocol (SNMP) or Internet Protocol Detail Records (IPDR), the later being preferred due to

DOCSIS Security | Uncapping Cable Modems

Mia Colabrese2012-08-14T10:57:21-04:00August 14th, 2012|

So what is uncapping cable modems? Uncapping cable modems refers to activities performed to alter a DOCSIS cable modems settings. Plain and simple someone is messing with the cable modem's configuration file to get what they want. So what do they want? Greater bandwidth (the need for speed), wanting more than one public IP, or any other configurable options a DOCSIS modem can offer. Maybe they just want to prove they can do it and or feel they are getting the shaft from their cable provider. Really the psychology of people is
