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

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. Moderator: Brady Volpe, CTO & Founder, The Volpe Firm, Inc. Advanced DOCSIS® vs. EPoC: A Residential Case

DOCSIS and Cable Modems – How it works :: Upstream RF

Mia Colabrese2021-08-17T13:29:04-04:00February 5th, 2009|

Cable modems use RF (radio frequency) signals to transport data over hybrid-fiber coax (HFC) networks according to the DOCSIS® specification. This blog will discuss the finer points extracted from the DOCSIS specification related to how cable modems communicate with the headend Cable Modem Termination System (CMTS), allowing two-way transport of Ethernet traffic over a cable TV network. There are currently three major revisions and one sub-revision of the DOCSIS specification; DOCSIS 1.0, 1.1, 2.0 and 3.0. With each major revision came significant changes to the cable modem upstream specification because the upstream has typically been the bottleneck in terms of data through-put rates as will be discussed.
