Bi-directional optical link between multiple data sources and a processing node in an avionics platform
First Claim
1. A fiber optic link suitable for avionics or naval platforms having a number of platform data sources, comprising:
- a processing node associated with an integrating network or bus of platform;
an array of one or more optical transmitter/receiver (TXn/RXn) pairs located in the vicinity of the processing node;
an interface for coupling said array with the integrating network;
a number of data modules each of which is coupled to one or more associated platform data sources and includes (a) an optical receiver operative to detect control data input to the module, and (b) an optical modulator arranged to modulate a light signal according to signals received from the associated data sources, andat least one optical fiber coupled between a given transmitter/receiver pair of said array, and a corresponding data module;
wherein a given transmitter of the array has an associated laser source operative to supply a light signal including said control data to an input of a corresponding data module downstream over an optical fiber, the modulator of the corresponding data module modulates the light signal according to the signals received from the associated data sources, and the modulated light signal is returned to an array receiver upstream over an optical fiber.

Abstract
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.
