Abstract
A system and method for transmission and receipt of signals within a distributed system are disclosed. In the distributed system there may be a plurality of digital and radio frequency (RF) electronics. The plurality of digital electronics may be coupled to the plurality of radio frequency electronics with at least one fiber optic cable. The at least one fiber optic cable may support wavelength division multiplexing (WDM). Further, the digital electronics may combine a time-at-the-tone signal, a pulse per second signal, and a standard frequency reference signal via amplitude modulation to produce a single complex wave. The single complex wave and other signals may be simultaneously transmitted along the at least one fiber optic cable to the plurality of RF electronics via WDM.
