CableLabs takes another step towards 10G with DOCSIS 4.0 specs CableLabs has released the specifications for DOCSIS 4.0, a technology that will put the industry on a path toward speeds of 10 Gbit/s downstream and up to 6 Gbit/s in the upstream. CableLabs said the raw speeds enabled by DOCSIS 4.0 on widely deployed hybrid fiber/coax (HFC) networks represent a doubling of the max downstream available via DOCSIS 3.1 and a quadrupling of the upstream capacity of D3.1. DOCSIS 4.0 also covers advanced capabilities such as enhanced security and low latency. CableLabs won't speculate on when it will be ready to start DOCSIS 4.0 product testing, let alone estimate when the first D4.0 products will be ready for trials and commercial deployments. But cable engineers and other industry insiders expect the DOCSIS 4.0 era to take several years to unfold.
