Abstract
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.
