Faced with upstream traffic surges of 30% or more because of COVID-19 lockdowns and other restrictions, cable operators have been scrambling to boost their upstream capacity to handle the pandemic's lingering impact on their HFC networks.
With the aid of vendors, operators are focusing on both short and long-term relief measures, such as splitting more fiber nodes; deploying lower-gain amplifiers; executing mid-splits and high-splits; extending plant spectrum to 1.8 GHz and beyond; and leveraging technologies and techniques like Profile Management Application (PMA), Orthogonal Frequency Division Multiple Access (OFDMA) and dynamic upstream configuration management to expand their upstream capacity.
In this session, we will delve into the various upstream expansion maneuvers, the challenges involved and the ways to overcome those hurdles.
