摘要： A fiber optic link for platforms with data sources including, e.g., sensors, cameras, radars and antennas. An array of optical transmitter/receiver pairs is coupled to an integrating network of the platform. Data modules are each coupled to certain ones of the data sources and include a receiver for detecting control data, and a modulator for modulating a light signal according to signals from the module's data sources. At least one optical fiber is coupled between a given transmitter/receiver pair of the array, and a corresponding data module. A laser source associated with each transmitter supplies a light signal with the control data to a corresponding data module downstream over an optical fiber. The light signal is modulated by the signals from the module's data sources, and the modulated light signal is returned to an array receiver upstream over an optical fiber.

摘要： An optical network and an optical signal modulation method thereof are provided. The optical network includes an optical fiber and a remote node (RN). The RN receives a continuous carrier wave from the optical fiber and modulates the continuous carrier wave to generate a first frequency offset carrier wave The frequency of the first frequency offset carrier wave is different from that of the continuous carrier wave. A first user device re-modulates and loads data to the first frequency offset carrier wave to generate a first upstream signal. The frequency of the first upstream signal is the same as that of the first frequency offset carrier wave. The RN inputs the first upstream signal into the optical fiber.
