Follow. An optical fiber (or optical fibre) is a flexible, transparent fiber made of high quality extruded glass (silica) or plastic, slightly thicker than a human hair. It can function as a waveguide, or âlight pipeâ, to transmit light between the two ends of the fiber. 9. 2  Special-purpose fiber â¢ Some special-purpose optical fiber is constructed with a non-cylindrical core and/or cladding layer, usually with an elliptical or rectangular cross-section. â¢ 3  These include polarization-maintaining fiber and fiber designed to suppress whispering gallery mode propagation.

KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury.The thyroid gland is the part of the body that is most sensitive to radioactive iodine.ecause KI contains so much stable iodine, the thyroid gland becomes âfullâ and cannot absorb any more iodineâeither stable or radioactiveâfor the next 24 hours. KI (potassium iodide) may not give a person 100% protection against radioactive iodine.
