Dense Wavelength Division Multiplexing (DWDM) is a technology that increases bandwidth by allowing multiple data streams to be sent simultaneously over a single optical fiber. It works by using different wavelengths (or colors) of laser light to carry different signals, effectively multiplying the capacity of the fiber. This technology is crucial in the telecom and network management industry as it enables efficient and high-capacity data transmission, meeting the growing demand for faster and more reliable internet services.
