Looking ahead: Next-gen broadband networks aim for speed with DOCSIS 4.0 and PON

The next chapter in cable and fiber networks will see cable operators focus on a new phase of their widely deployed hybrid fiber/coax (HFC) networks as telephone companies – and some cable operators – maintain their pursuit of speedier passive optical network (PON) and Ethernet technologies. DOCSIS 4.0 represents the next generation of HFC, enabling symmetrical multi-gigabit speeds, enhanced security and lower latency. The products and technologies that will underpin DOCSIS 4.0 are expected to mature in the coming year as modem makers start to develop devices that are powered by a new generation of chipsets. Out on the network, expect suppliers to continue pushing amplifiers and other outside plant equipment focused on 1.8Giga Hertz technology – a key component of future D4.0 upgrades that will utilize the ESD option.
