DOCSIS 3.1 technology enables a new generation of cable services and helps operators continue to meet consumer demand for high-speed connections and sophisticated applications, positioning them to be the providers of choice in their markets.
DOCSIS Technology Delivers Speed
DOCSIS 3.1 technology includes the latest and greatest of digital communication technologies such as LDPC encoding, very high modulation orders (4096 QAM for example), more than 1 GHz of usable spectrum and support of QoS and low latencies. DOCSIS 3.1 technology delivers all of this while maintaining backward compatibility to DOCSIS 3.0 technology and the ability to deploy it on today’s HFC network without any requirement to upgrade today’s plants.
The Impact of DOCSIS Technology
Deployment of DOCSIS 3.1 technology provides significant new value for cable operators and consumers of broadband services including:
SPEED
Support for up to 10 Gbps downstream and up to 1 Gbps upstream network capacity.
QUALITY OF EXPERIENCE
Utilizes Active Queue Management to significantly reduce network delay as data traffic grows in the home network, dramatically improving responsiveness for applications such as online gaming.
HIGHER CAPACITY ON EXISTING NETWORKS
Enables a significant increase in network capacity with the ability to transmit up to 50 percent more data over the same spectrum, on existing HFC networks.
ENERGY EFFICIENCY
Enhancements to the DOCSIS protocols increase cable modem energy efficiency through advanced energy management protocols.
The Evolution of DOCSIS
As an evolution of DOCSIS technology, a DOCSIS 3.1 network provides a flexible migration for cable operators, with the ability for DOCSIS 3.1 modems to coexist with older versions and build on top of the previously deployed capacity. The higher efficiency of DOCSIS 3.1 technology also enables significant cost per bit reductions relative to DOCSIS 3.0 network solutions. In partnership with global members, CableLabs has provided a unified DOCSIS specification.
2017: CableLabs is currently adding to the DOCSIS 3.1 specifications to include Full Duplex DOCSIS.
DOCSIS Technology Delivers Gbps Services
There is a lot of excitement around DOCSIS 3.1 technology , and the new capabilities it brings to cable networks for both cable operators and their customers. Customers will enjoy gigabit speed access on the downstream and upstream, allowing them to download 4K video and ultra-high definition movies faster than ever. Reduced network delay will also take the online gaming experience to a new height, increasing responsiveness and allowing higher resolution graphics. Also, the widespread availability of cable high-speed internet will make high speed broadband available to more households than any other technology.
