Remote PHY, part of the DOCSIS 3.1 specifications, is a Distributed Access Architecture (DAA) intended to help service providers push capacity to the edge, leverage current investments and densify access networks to flexibly deliver video, voice and data while supporting bandwidth growth.
CableLabs interoperability events, hosted by Kyrio, are intended to provide vendors with the opportunity to test pre-production and development versions of hardware and software in a multi-vendor environment and/or with CableLabs-provided testing platforms. The interop event allows a variety of manufacturers an opportunity to work together in CableLabs' laboratory environment to develop and test interoperable solutions. At CableLab's January interop event, Casa was able to interoperate using open standards with multiple vendors' Remote PHY Devices (RPDs). Additionally, Casa demonstrated its own RPD registering on a third-party cable core.
"Transitioning from a centralized cable access architecture to a distributed network is a significant step for most service providers," said Jerry Guo, CEO at Casa Systems. "Interoperability of our Remote PHY solutions is a major goal in our strategy to help our service provider customers more quickly realize the benefits of the latest architecture."
