    摘要: Methods and apparatus for removing beat interference from the splitting and/or combining of signals. In one embodiment, an active splitter/combiner receives multiple input optical signals from downstream communication resources via a number of individual point-to-point links. Each input optical signal is converted to an electric signal (which, unlike the input optical signals, do not share a characteristic wavelength). The resulting electrical signals can be combined without introducing beat interference. Once combined, the resulting aggregate signal is converted back to an optical format for transmission via the optical network. Various other aspects of the present disclosure are directed to active splitting of optical signals.

    摘要: Embodiments include systems and methods for scaling power level of an upstream signal by a device processor of a head-end device in a communication network. In embodiments, the device processor may determine a power level of the signal received at the head-end device from a client device. The device processor may determine a difference between the power level of the received signal and a target power level of an analog-to-digital converter of the head-end device, and may adjust the power level of the received signal at the head-end device based on the determined difference. In embodiments, the device processor may determine a power level of an upstream signal to be received by the head-end device, may determine a difference between the power level of the received signal and the target power level, and may adjust the power level of a received signal at the head-end device based on the determined difference.
