CableLabs highlight DOCSIS 3.1 details

October 31, 2013 - 11:55am
High speed data transfer standards continue to evolve.

The DOCSIS standard is one of the broadcast industry's most critical components, as it enables cable service providers and system operators to augment infrastructure to satisfy consumer demand for fast connections. DOCSIS 3.0 is the most recent standard in wide use, originally released in August 2006. However, CableLabs, which produces the DOCSIS standard along with a consortium of other industry companies, announced details for DOCSIS 3.1 at the recent SCTE Cable-Tec Expo, according to the Broadband Technology Report.

Available details about what DOCSIS 3.1 is expected to offer, according to the news source, include:

  • Speed support for 10 Gbps downstream and 2 Gbps upstream
  • Active queue management to reduce latency
  • Interoperability between DOCSIS 3.1 modems and legacy versions
  • Fifty percent more data capacity over the same spectrum as DOCSIS 3.0
  • Compatibility with existing HFC networks

Testing and analysis is important when introducing a new standard and corresponding equipment into a video broadcast system. CableLabs stated that it will conduct interoperability testing once a DOCSIS 3.1 prototype becomes available. At the expo, CableLabs also announced an "enhanced partnership" with SCTE to share development and innovation processes, which will likely accelerate the introduction of new technologies, according to FierceCable. It's important for network operators to continue to update analysis solutions to ensure that their systems are functioning properly when equipment using different standards is in play.
