    Classification of Optical Fiber Communication Signal Wavelengths

    Optical communication is mostly conducted in the wavelength region from 1260 to 1625 nm. The region comprises five bands called the O-, E-, S-, C- and L-bandsThis article introduces the concept of optical wavelength bands, explains how they are classified, explores how WDM (Wavelength Division Multiplexing) uses them to increase capacity, and highlights common use cases. The values presented below are approximate and should be considered as such, as standardized values are still evolving. This standardization ensures interoperability between different manufacturers' equipment and facilitates the global deployment of fiber optic networks.
