Fiber wavelength multiplexing

WebInverse multiplexing speeds up data transmission by dividing a data stream into multiple concurrent streams that are transmitted at the same time across separate channels (such as a T-1 or E-1 lines) and are then reconstructed at the other end back into the original data stream. Just the reverse of ordinary multiplexing , which combines ... WebWavelength division multiplexing (WDM) is a technique that allows multiple signals to be transmitted over a single fiber by using different wavelengths or colors of light. Each …
