By Nick Segura – As cable operators upgrade their HFC networks on the path to 10G, implementing a high-split 204 MHz architecture is a viable solution. This prevalent approach can deliver solid results with proper planning and foresight, particularly around modem transmit levels.
Read MorePratyusha Malladi – Different measurement methodologies, equipment calibration, and RF receiver characteristics can lead to inconsistent results. This makes it challenging to compare systems, or even draw definitive conclusions based only on these metrics.
Read Moreby Michael Kloberdans – Cable operators have many tools in their toolkit to provide higher speeds and symmetrical bandwidth offerings to customers. In particular, DAA enables increased modulation orders by driving PHY/MACPHY functionality closer to the customer and utilizing digital fiber.

By Nick Segura – Artificial intelligence in our industry is imminent, so why can’t we begin building this into amplifiers and coin the term “amplifier-intelligence” (AI)?
Read MoreDavid Claussen – FMA is a natural evolution of the existing DOCSIS infrastructures, with considerations to have new systems coexist with current systems. While not without a learning curve, FMA offers performance and flexibility to cable operators largely unavailable today.
