WebGeneration: The major disadvantage of the 3. Generation. optical communication system is the fact that the signals are. regenerated by electrical means. The optical signal is transferred. to an electrical signal,the signal is regenerated and amplified. before the signal is again transferred to an optical fiber. 4. WebThe optical layer is a wavelength-based concept and lies just above the physical layer The physical layer provides a physical connection between two nodes The optical layer provides light path services over that link The optical layer processes include wavelength multiplexing, adding and dropping wavelengths, and support of optical switching 6
