By Steve Condra – In 2019 Teleste took the initiative to help operators in their 1.8 GHz considerations and performed measurements in a real network environment [2] to find out what can be expected of 1.8 GHz capable network elements and how operators can obtain the most out of their networks with minimal changes. The study focused on two questions:

By Steve Condra – As the study concluded, even four amplifiers in a cascade can carry the magical 10 Gbps capacity. However, it is clear that to harvest the full potential of HFC networks, 1.8 GHz amplifiers should perform automatic adjustments. Alternatively, cable technicians should define rigorous methods to confirm that amplifier cascades are tuned to perfection even when outdoor conditions, such as temperature, change.
