Cisco ‘Infinite Broadband’ Remote PHY solution

Cisco is meeting with its cable operator customers at SCTE Cable-Tec Expo to demonstrate how it is disrupting the industry through its technology innovations.

Cisco’s Infinite Broadband Remote PHY solution (RPHY) for cable access networks, the industry’s only standards-based distributed access architecture (DAA) on the market. Remote PHY refers to the technique of moving the physical ‘PHY’ circuit layer out of a headend device such as a converged cable access platform (CCAP), and putting it into a distributed device at the edge of the network (RPHY Node), or a smaller hub-site (RPHY Shelf) to be closer to the customer.

Cisco’s RPHY solution is based on open, standardised software that was contributed to Cable Labs OpenRPD forum in 2016. This open source initiative creates an ecosystem of Remote PHY device (RPD) vendors, allowing operators to select an RPD vendor that best meets their needs, without being locked into a single vendor’s proprietary solution.

“Blue Stream customers want Gigabit broadband services. It is a ‘must have’ to deliver what our customers want to any device,” said Joe Canavan, chief operating officer, Blue Stream. We were looking for the best way to expand our footprint and deliver high-speed data, video and voice to new service areas from our existing headend infrastructure. Cisco’s Remote PHY solution has helped us deliver these services over a single IP link and single platform exactly how and where we needed. We worked closely with CCI Systems for the Remote PHY solution design, as well as video and IP network integration services.”
