What is the minimum gain amplifier required in the headend room for a specific video service extension?

In video service extension, the signal loses strength as it travels through cables, taps, and other components. To ensure the far end still meets the required level for proper reception, the headend needs to provide just enough amplification to offset that loss. If the extension’s path has about 15 dB of total loss, the minimum gain needed in the headend is 15 dB, so the signal arrives at the required level with no shortfall and with a small buffer for margins. Providing less than that leaves the signal underpowered, while providing substantially more gain can push the system into overload and distortion. So the smallest gain that satisfies the extension’s requirements is 15 dB.
