hullámhosszmegosztásos
Hullámhosszmegosztásos, often abbreviated as WDM, is a telecommunications technology that allows for the transmission of multiple optical signals over a single optical fiber. Each signal is assigned a unique wavelength, which corresponds to a specific color of light. By utilizing different wavelengths, these signals can coexist on the fiber without interfering with each other.
The core principle of WDM relies on the ability to multiplex (combine) and demultiplex (separate) these different
There are two primary types of WDM: coarse wavelength division multiplexing (CWDM) and dense wavelength division
WDM technology is fundamental to modern optical communication networks, including long-haul telecommunications, metropolitan area networks, and
