DOCSIS 4.0 is the latest version of the DOCSIS set of specifications, promising download speeds of 10 Gbps while also reaching 6 Gbps upstream speeds. This to allow for multi-gigabit symmetric services such as video conferencing, remote work/learning, health care applications, IoT and virtual reality over HFC networks.

The goal of this course is to provide insight into how this new DOCSIS version allows to get those high symmetrical speeds and based on use cases found out what the possibilities are for your HFC, CM and CMTS roadmap. Important changes in security also will be discussed.

It is highly recommended that the attendee already has a good knowledge of DOCSIS 3.1 to fully benefit of attending this course. This by attending the DOCSIS 3.1 training first or by having a 3.1 Refresher training.

Achieve an in-depth understanding of the technological evolution and its advantages along with the new concepts introduced in DOCSIS 4.0.

An overview of the different options, characteristics and potential gains

After attending this course, the attendee will be capable of understanding the main DOCSIS 4.0 concepts, terminology, field deployment options, and communication from CM and CMTS perspective

Prerequisites: Attended Technology & Protocol Level 1 training + DOCSIS 3.1
