Abstract
A transmitter may include a digital signal processor (DSP) to generate an electrical signal associated with a beacon and a data signal. The transmitter may include an electro-optical component to convert the electrical signal to an optical signal to be transmitted by the transmitter. The beacon and the data signal may be on a common wavelength in the optical signal. A power of the beacon within the optical signal may be based on a value of an amplitude modulation factor applied to the beacon by the DSP in association with generating the electrical signal.
