                          Singlemode optical fiber is the backbone of modern telecommunications and data transmission systems. While many engineers associate singlemode fiber with the standard 9\/125 \u03bcm core\/cladding structure, the performance characteristics vary significantly depending on the fiber standard. Among the most widely used are G.652.D, G.657.A1, and G.657.A2, each defined by the International Telecommunication Union (ITU-T).
