A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. They're designed for long distance, very high performance data networking and telecommunications. Compared to wired cables, fiber optic cables provide higher bandwidth and can transmit data over longer distances. Fiber optic cables support much of the world's internet, cable television and telephone systems. Fiber optic cables carry communication signals using pulses of light generated by small lasers or light-emitting diodes (LEDs). The cable consists of one or more strands of glass, each only slightly thicker than a human hair. The center of each strand is called the core, which provides the pathway for light to travel. The core is surrounded by a layer of glass called cladding that reflects light inward to avoid loss of signal and allow the light to pass through bends in the cable. The two primary types of fiber cables are called   single mode  and  m...

Ultraviolet (UV) radiation is a type of energy produced by the sun and some artificial sources, such as solariums.  Ultra-violet (UV) lasers for Raman spectroscopy typically include laser wavelengths ranging from  244 nm through to 364 nm . UV radiation isn’t like the sun’s light or heat, which we can see and feel. Your senses cannot detect UV radiation, so you won’t notice the damage until it has been done. Theoretically UV Raman spectroscopy is no different from standard analysis using visible laser wavelengths.  However, in practice there are a  small amount that gets through has both positive and negative effects.  Positive effects of UV Photolithography:  UV is employed in fine resolution photolithography and hence is extensively used in the field of electronics. Vitamin D Production :  UV from the Sun is needed by our bodies to produce vitamin D. Vitamin D helps strengthen bones, muscles and the body’...
