Abstract
The present invention is directed towards monitoring and adjusting a power level of reverse subcarrier signals at an input of an optical node as opposed to at an input of a CMTS blade. Advantageously, reverse subcarrier signals are digitally transmitted throughout the optical link thereby avoiding the use of attenuators in the optical link. Therefore, any attenuation of the power level of the reverse subcarrier signals is caused by an RF feeder portion of the communications system. The CMTS blade then detects the power level of the reverse subcarrier signal that is equivalent to the power level at the input of an optical node and sends a control signal to CPE adjusting the transmitter power level without affecting the optical node dynamic range.
