Nokia DWDM & Optical Transmission Systems
      Nokia DWDM & Optical Transmission Systems leverage Dense Wavelength Division Multiplexing to transmit high-capacity data over a single fiber by multiplexing multiple wavelengths of light, allowing for ultra-high bandwidths up to Tb/s. Key components include the 1830 Photonic Service Switch (PSS) family and Photonic Service Engine (PSE) chipsets that provide advanced digital signal processing (DSP), coherent optics, and flexible grid technology. These systems scale from compact metro and access networks to long-haul, subsea, and Data Center Interconnect (DCI) applications, offering high scalability, cost-efficiency, reliability, and improved power efficiency.
