DOCSIS 3.1 is the latest version of the DOCSIS set of specifications, promising download speeds of up to 10 Gbps. It defines a totally new physical layer for achieving those speeds. However, to fully utilize its features, major HFC network upgrades are required.
The goal of this course is to provide insight into how the new physical layer operates, the impact on the network and how the HFC network needs to be modified. The course also provides a good understanding of the speeds that can be offered by 3.1 based on network parameters.
It is recommended that the attendee already has a good knowledge of DOCSIS to fully benefit of attending this course.
What can you expect?
- Achieve an in-depth understanding of the technological evolution and its advantages along with the new concepts introduced in DOCSIS 3.1.
- An overview of the different features and characteristics
- Calculation of the speeds that can be offered by 3.1 based on network parameters
- After attending this course the attendee will be capable of understanding the DOCSIS 3.1 concepts, numerology, configuration and monitoring.
