Remote PHY (R-PHY) is a key component in the cable industry’s adoption of a Distributed Access Architecture (DAA). This Deep Dive course examines Cisco’s deployment of R-PHY architecture and devices.
Remote PHY (R-PHY) is a key component in the cable industry’s adoption of a Distributed Access Architecture (DAA). DAA and R-PHY are foundational technologies for future innovative network architectures such as Virtual CMTS (vCMTS), Cloud Native Broadband Router (cnBR), and Full-duplex DOCSIS. R-PHY enables the migration of physical layer (PHY) functions (such as RF Spectrum generation) from the Headend to the network edge – leading to more robust RF networks. The deployment of DAA/R-PHY, coupled with DOCSIS 3.1, allows cable operators to deliver ultra-broadband services with maximum downstream/upstream speeds approaching 10 Gbps/1 Gbps respectively.
Instructor did a great job, from experience this subject can be a bit dry to teach but he was able to keep it very engaging and made it much easier to focus.
Excellent presentation skills, subject matter knowledge, and command of the environment.
Instructor was outstanding. Knowledgeable, presented well, and class timing was perfect.
