Full Duplex DOCSIS® 3.1 Specification Effort Launches
During the CableLabs 2016 Winter Conference, CableLabs announced the Full Duplex DOCSIS 3.1 (now DOCSIS 4.0 technology) specification project that will significantly increase upstream speeds on the DOCSIS network. The announcement of the Full Duplex (now DOCSIS 4.0 technology) extension of the DOCSIS 3.1 specification, and its potential of offering multi-Gbps symmetric services over the HFC network, created a lot of excitement in the industry. Since then a lot has been going on behind the scenes.
CableLabs has been actively collaborating with the vendor community to further refine the concept and system architecture of a Full Duplex DOCSIS 3.1 (now DOCSIS 4.0 technology) system. The ecosystem support for the Full Duplex DOCSIS 3.1 technology (now DOCSIS 4.0 technology) has been staggering, with many vendors collaborating and contributing to the development of the technology. A recent example is Cisco’s contribution of a new silicon reference design of a digital echo canceler that maximizes the use of HFC capacity to provide a scalable multi-gigabit return path.
In June, CableLabs officially launched the Full Duplex DOCSIS 3.1 (now DOCSIS 4.0 technology) project, transitioning it from the innovation phase to the R&D phase focused on specification development. Our first face-to-face meeting held in Louisville last month featured strong participation from CableLabs members and the vendor community including several new participants. Working group meetings will be held on a regular basis until the specification development is complete.
Full Duplex DOCSIS 3.1 technology (now DOCSIS 4.0 technology) will radically change the art-of-the-possible on the HFC network by delivering an unparalleled experience to cable customers.
