Moving towards DOCSIS 4.0 and extended spectrum DOCSIS (ESD) networks is elemental before the cable industry’s vision of a 10G future becomes a reality. With these technologies, operators can build multi-gigabit networks – both upstream and downstream – without capex-intensive fibre-to-the-home (FTTH) investments.

  • Multi-gigabit broadband speeds to subscribers
  • Less latency to enable a “real-time” online experience
  • More reliability to meet consumers’ need for an uninterrupted and secure internet connection

The 1.8 GHz networks 10G maximum speeds are feasible through many concepts and no ‘one size fits all’ solution exists to ease operators’ strategy work. For a successful roadmap to future, operators need to know which devices to use, how and where. It is important that detailed planning and decisions on what aspects of the network – performance, costs, or practicality – are emphasized in each upgrade. We are working on many fronts to help our customers and the industry to move forward.

Extended upstream in practice: Towards the high-split

Today we see many European cable operators moving or planning to move from 65/85 MHz to 204/258 MHz high-split cable networks. In his blog, Arttu Purmonen shares insight on what the transformation means in practice.

Are you hunting the last bits?

Moving to 1.8 GHz requires access networks that tolerate high total composite power (TCP) and support different split ratios from mid- to high-split and beyond. A careful network plan for how to harness extended downstream and upstream frequencies for full use requires a deep understanding of how amplifier cascades behave.
