In CATV systems, losses of which dB range should not require amplifiers?

In CATV design, you must keep the total attenuation from the headend to the farthest subscriber within what the receivers can tolerate and still deliver a usable signal. Amplifiers are added only when the passive loss would push the signal below that threshold. A typical passive loss budget sits around 10 to 13 dB, meaning if the network accumulates about 10 to 13 dB of loss without considering active boosting, you can usually rely on the system’s existing levels and no additional amplification is needed. This range reflects a practical balance where the signal remains strong enough across the plant while avoiding the added noise and distortion that an amplifier could introduce. Losses outside this window would more likely require an amplifier (if higher) or rely on margins that aren’t standard practice for ensuring reliable reception.
