DWDM (Dense Wavelength Division Multiplexing) is a fiber-optic transmission technology that enables high-capacity data transfer by sending multiple data streams over a single fiber using different light wavelengths. This allows for increased bandwidth and improved network efficiency, making DWDM a key technology in modern telecommunications and cloud infrastructure.

In the context of cloud storage and data centers, DWDM plays a crucial role in high-speed data transmission between geographically dispersed cloud facilities.

DWDM ensures low-latency, high-speed connectivity for distributed cloud storage networks, allowing businesses to transfer large datasets securely and efficiently. By leveraging DWDM, cloud providers enhance redundancy, scalability, and disaster recovery capabilities, ensuring uninterrupted access to critical data.
