The full duplex (FDX) DOCSIS extension to the DOCSIS 3.1 specification has been finalized in Annex J of that spec. What does this mean?

I covered some of this in the Spring 2018 issue of Broadband Library on FDX which you can find here: https://broadbandlibrary.com/full-duplex-docsis/ and will further explore the benefits of FDX now. Why FDX Now? Why am I focusing

Demystifying OOB and R-PHY

Mia Colabrese2020-04-02T12:21:56-04:00December 14th, 2018|

Benefits and Limitations, Choose your R-PHY Wisely In this article we dive into Data-Over-Cable Service Interface Specifications (DOCSIS) remote PHY (R-PHY) testing challenges and how these can be overcome using out-of-band (OOB) channel communications. Test and Measurement Challenges with R-PHY Let’s understand the fundamental challenges with testing in an R-PHY world. Today’s radio frequency (RF) test equipment, such as sweep, return path monitoring, and leakage is based on analog signals. Figure 1 illustrates how typical headend / hub test equipment signals traditionally flow to or from an analog

Data-Over-Cable Service Interface Specifications (DOCSIS) version 3.1 offers a host of exciting possibilities and realities for cable operators. I have covered many of these topics in previous articles but the one thing that cannot be overlooked is the basics. It doesn’t matter how great these new technologies are if you do not pay attention to the foundation. It’s not any different than a house. If your foundation isn’t solid who cares if you have the best theater system in it. It can crumble under foot if the foundation
