SIGINT’s (Signals Intelligence) current operational environment often requires rapid development of waveforms, protocols, and devices to dependably function in different environments. The best solutions for such functions are Software Defined Radios (SDR), which are the principal solution to prototype wireless communication systems leading to better solutions quickly. NI has adequately identified the following requirements to fulfill client needs and specifications:

Fiber optics use hair-like glass fibers to cany modulated light to transmit signals over distances. Light signal systems use simpler equipment, less energy, and are less prone to interference. The glass fiber has a clear core to carry the light and a cladding that is highly reflective, as well as a protective coating. Light beamed into the core is reflected from side to side to keep it moving down the core. An electronic signal, such as a telephone signal, is converted to a light beam by a light generator, which can be a light-emitting diode (LED) or a laser diode. The light is transmitted down the fiber through various optical connectors, jumpers, patch panels, etc., and is picked up at the receiving end by a photodetector that converts it back to an electronic signal. Long cable runs use weld-like splices. Clear optical continuity is needed for light transmission.

A dielectric is an insulating material, but it is an insulating material that has been manufactured with certain electrical characteristics to interact with other electrical characteristics of a component to give the component its ratings. The insulating material between the plates of a capacitor is a dielectric. It helps determine the capacitance value and must resist voltage breakdown at the rated voltage of the capacitor.
