... and the other way around make the whole process of switching more complicated and therefore people are already looking for a solution for this. First, people wanted to use moving mirrors to switch the direction of the beam of light, but this solution presents a lot of problems, under which the cost, size, mechanical complexity and the speed limitations of moving mechanical parts. But Agilent a company working with fibre ... optics found another source that also reflects light namely bubbles. The company started researching this option to change the direction ... ...

... more importantly, labor costs force us to consider other alternatives. Two solutions are TDM and WDM. Solutions to Bandwidth Demand TDM TDM improves the efficiency of a single fiber by combining many lower-speed transmissions into a single higher-speed transmission using time slicing. Synchronous Optical Network (SONET) used primarily in North America and Synchronous Digital Hierarchy (SDH) used primarily in Europe and Japan ... onto the fiber. It uses an optical wavelength multiplexer to essentially put multiple carrier wavelengths on the fiber optic at the same time. Instead of a singl...
