Abstract: A communications device may include a remote device having a first E/O modulator to modulate an optical carrier signal with an input signal having a first frequency, an optical waveguide coupled to the remote device, and a local device coupled to the optical waveguide. The local device may include an optical source to generate the optical carrier signal, a second E/O modulator to modulate the optical carrier signal with a reference signal to generate a modulated reference signal, an OIL source coupled to the second E/O modulator and to amplify the modulated reference signal, and an O/E converter coupled to the OIL source and to generate an output signal including a replica of the input signal at a second frequency based upon the reference signal.
