DOCSIS 4.0 - Pimp my DOCSIS

On the way to 10 Gbps symmetrical – DOCSIS 4.0 in focus

With the DOCSIS 4.0 standard, the cable industry has taken a significant step in the further development of data transmission technology. While numerous networks around the world are still being upgraded to DOCSIS 3.1, CableLabs published the specifications for DOCSIS 4.0 back in March. This article provides an in-depth look at the latest generation of the cable standard and compares it with its predecessors. DOCSIS 4.0 not only promises higher speeds and improved efficiency, but also brings with it new challenges. With a target symmetry of 10 Gbps downstream and 6 Gbps upstream, DOCSIS 4.0 represents a significant step forward. The standard integrates both full-duplex and extended spectrum technologies and offers solutions for increased bandwidth requirements and reduced latency. Our comprehensive article sheds light on the technical details, history and future prospects of this standard. For a deeper and more detailed analysis, we invite you to download the full PDF.
