Abstract
An example device may include an optical configuration configured to transmit a transmitted optical beam and receive a received optical beam, an optical modem, and an optical amplifier. An example optical amplifier may include an optical gain medium and an optical bandpass filter. The transmitted optical beam may have a transmit wavelength selectable from a plurality of transmit wavelength, and may have a different wavelength from the received optical beam. In some examples, the optical configuration may include at least one dichroic element. Various other devices, systems, and methods are described.
