Why did the cable industry choose 75-ohm coaxial cable — and not 50 ohms? The answer is rooted in physics, engineering tradeoffs, and decisions made decades ago that still define every HFC network running DOCSIS today. Brady Volpe and Ron Hranac break down one of the most fundamental design choices in cable network history: why

The “Fun-house Mirrors” of a Cable Plant What’s an echo cavity, really? Clap your hands and you hear one echo if the sound hits one wall and bounces back. Now clap between two mirrors facing each other— the sound keeps ping-ponging. In a cable network, the signal (instead of sound) bounces between two bad spots

Brady Volpe and John Downey discuss the theory of operation of return path signal levels in the return path. Why does the transmit power increase, rather than decrease like the downstream? How do two way splitters impact upstream and downstream signal levels? Why is the return always higher than the value the of tap

A Lesson on Transmission Line Theory Transmission line theory can be intimidating, because of the complex mathematics involved. But I’m not going there. Transmission line theory is further complicated by modeling, say, coaxial cable (a transmission line) as a distributed circuit model, comprising series inductance, shunt capacitance, series resistance, and shunt conductance. But I’m not

OFDM and OFDMA The value added and what it means to my network By now you have heard or have been exposed to orthogonal frequency division multiplexing (OFDM). It was the innovative technology introduced in Data-Over-Cable Service Interface Specifications (DOCSIS) 3.1 to increase the efficiency by which DOCSIS networks can transmit data in the downstream.
