The Fundamentals of Wave Division Multiplexing
Wave division multiplexing is a technology in which various optical carriers’ signals are multiplex into a single optical fiber by utilizing different wavelengths like colors of laser light. While wave division multiplexing is characterized by wavelength, frequency division multiplexing which is commonly applied to the radio carrier is characterized by the frequency. This is absolutely conventional because both of them convey the same information. What are WDM systems? In WDM systems, a multiplexer is used at the transmitter side to connect various signals together and the receiver side, a demultiplexer is used to separate the multiplex signals. Traditionally the optical filters that are used in the WDM systems are Fabry-Perot interferometers. WDM frameworks are generally favored by Telecommunications organizations since they permit them to grow the limit of the system without laying more fiber. By utilizing WDM, they can suit a few ages of innovation improvement in t...
