Where are upstream levels and sweep responses measured in an HFC network?

• A. The distribution node
• B. The headend
• C. The customer premises
• D. The optical node

Answer: (B)

In a Hybrid Fiber-Coaxial (HFC) network, upstream levels and sweep responses are primarily measured at the headend. The headend serves as the central hub for the network where signals are received, processed, and sent out to the distribution network. Measuring upstream levels at this location allows technicians to analyze the quality of signals being sent from customer premises back to the network. Additionally, measuring at the headend provides valuable data for optimizing network performance and troubleshooting any issues with signal integrity or communication between the various components of the network. It is essential for ensuring that upstream signals meet the necessary specifications for effective data transmission.
