CWDM and DWDM are methods within the broader field of wavelength division multiplexing (WDM). Both techniques utilize different wavelengths of light to transmit data over a single fiber optic cable, effectively increasing bandwidth and transmission capacity. CWDM operates with coarser segments between wavelengths, typically 20 nanometers, making it a less complex solution suitable for shorter distances. In contrast, DWDM employs much narrower intervals, often as little as 0.8 nanometers, enabling a higher density of wavelengths and thus greater bandwidth capacity over longer spans.
Choosing between CWDM and DWDM depends on several variables, including the required bandwidth, transmission range, budget constraints, and existing infrastructure. While CWDM offers a cost-effective solution for smaller networks, DWDM's high capacity makes it the preferred choice for large-scale deployments requiring extensive bandwidth.
