CableLabs increases Internet speeds on HFC Network

CableLabs®, the innovation lab for the secure delivery of high speed data, video, voice and next generation services, has completed its Full Duplex DOCSIS® 3.1 specification which significantly increases upstream capacity and enables symmetric multi-Gigabit services over existing hybrid fiber-coaxial (HFC) technology, the company said.

Anticipating a change in user demand as emerging technologies require more bandwidth, CableLabs´ Full Duplex DOCSIS technology will ensure that cable operators can be ready to meet future usage needs for technologies such as virtual and augmented reality.

Full Duplex DOCSIS 3.1 technology builds on the successful completion of CableLabs´ DOCSIS 3.1 specification, which made deployments of 10 Gbps downstream and 1 Gbps upstream broadband possible.

In current DOCSIS networks, spectrum is typically split between the upstream and downstream, or spectrum is shared between upstream and downstream traffic. Full duplex communication enables upstream and downstream traffic to efficiently use the same spectrum simultaneously, which can be beneficial for residential and business services. For businesses in particular, symmetric services can vastly improve network efficiency, which can, in turn, improve the customer experience on business websites.

By leveraging the combination of DOCSIS 3.1 technology, passive HFC network characteristics, self-interference cancellation technology and intelligent scheduling, CableLabs — along with the collaboration of its members and other industry partners — developed this solution enabling full duplex communications over the existing HFC network. The evolution also eliminates the need and cost of deploying fiber to the home while still maintaining backward compatibility with previous generations of DOCSIS technology.

For nearly 30 years, CableLabs has been at the forefront of innovation, transforming how humans, communities and industries connect. Dating back to the launch of HFC in 1992 to the start of DOCSIS® in 1994, CableLabs has directly impacted the landscape of tomorrow.
