This technique optimizes fiber optic cables by maximizing their data-carrying potential, ensuring efficient communication and network scalability.How WDM Works in Fiber Optic Networks
Last edited just now Wavelength-Division Multiplexing (WDM) enables multiple data streams to travel simultaneously over a single fiber optic cable by assigning each signal a unique wavelength of light. Using multiplexers and demultiplexers, WDM combines and separates optical signals, ensuring efficient, high-speed transmission without interference, significantly enhancing fiber optic network capacity and performance.Wavelength Assignment in Optical Transmission
Each data stream in WDM is assigned a distinct wavelength, typically in the infrared spectrum, which is optimal for transmission through fiber optic cables. The careful allocation of wavelengths prevents interference and ensures seamless data flow within the network.The Role of the Multiplexer in Fiber Optic Communication
A multiplexer is a device that combines multiple optical signals, each assigned a unique wavelength, into a single composite signal. This combined signal is transmitted through fiber optic cables, optimizing network efficiency and bandwidth utilization.Optical Transmission Through Fiber Optic Cables
Once the multiplexed signal is transmitted, it travels through fiber optic cables without interference. The integrity of individual data streams is maintained due to the distinct wavelength assignments, ensuring high-speed and reliable communication.Demultiplexing and Signal Recovery
At the receiving end, a demultiplexer separates the composite optical signal back into individual wavelengths. Each wavelength is then directed to its respective receiver, where the original data streams are recovered, ensuring accurate and efficient data transmission.Types of Wavelength-Division Multiplexing in Fiber Optics
Wavelength-Division Multiplexing (WDM) in fiber optics is categorized into Coarse WDM (CWDM) and Dense WDM (DWDM).
