Where does the fiber optic cable ultimately end up
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for fiber-optic communication in differen. DesignOptical fiber consists of a and a layer, selected for due to the difference in the between the two. In practical fibers, the cladding is usually coated wit. In September 2012, NTT Japan demonstrated a single fiber cable that was able to transfer 1 per second (10 bits/s) over a distance of 50 kilometers. Although larger cables are available, the highest stra.
