CableLabs has released the specification for DOCSIS 4.0, which includes both full duplex and extended spectrum capabilities.
The DOCSIS 4.0 technology is capable of achieving a downstream speed of up to 10 Gbps and doubles the maximum download speed available with DOCSIS 3.1 technology. The upstream speed of up to 6 Gbps represents a quadrupling of DOCSIS 3.1.
“As cable operators respond to the evolving connectivity needs of customers in our current public health crisis, remote work, learning, and health services stand to benefit from upstream broadband enhancements as DOCSIS 4.0 technology is deployed,” explained Doug Jones, Principal Architect, DOCSIS 4.0 in a blog post.
The DOCSIS 4.0 specification, part of CableLabs’ so-called 10G Platform began development in August 2016 with the extended spectrum capability completed last September.
In addition to speed Lower latency that was incorporated into the DOCSIS 3.1 specification has been brought forward into the DOCSIS 4.0 specification. Lower latency will provide for a better experience for consumers on applications such as online gaming and multimedia.
