Abstract: The present invention provides a kind of ultra-wide band wireless system, which changes the previous electronic structure for ultra-wide band pulse generator, and uses light to generate pulse signal, transformed by microwave differentiator to Gaussian monocycle pulse transmission signal, the derived pulse signal can provide several GHz bandwidth to transmit fast speed information, and further complete the new ultra-wide band wireless system. It reduces the complexity of electronic system and enhances output signal quality by means of light property, with considerable leading advantage. And the signal generated by this system has broader band and no infringe property, its 10 dB band falls within the range prescribed by the Federal Communication Committee of United States (FCC), successfully realizing the ultra wide band fiberoptic wireless collection network system, and further attaining the goal of seamless communication collection.

Abstract: The present invention is a self-healing fiber Bragg grating sensor system which comprises a central office, at least one network node, at least one 2×2 optical switch and at least one fiber Bragg grating. The network node can be made of optical switch. When the fiber for the sensor system is broken, sensing signals are discriminated in different paths provided by the network nodes to avoid stop working once the fiber is broken, by which the self-healing ability of the system is greatly improved. Besides, by using the structure of fiber laser in the present invention, the power output and the signal-to-noise ratio can be greatly increased. Accordingly, the present invention is to design a fiber sensor system with low cost and high capacity and with capability of self-healing.
