DWDM

Dense Wavelength Division Multiplexing (DWDM) is a technology that increases the capacity of fiber optic networks by transmitting multiple data streams simultaneously over a single fiber. It does this by using different specific wavelengths (colors) of laser light for each data stream. Think of it as combining many different radio stations into one cable, then separating them at the other end. This allows internet, phone, and data services to operate efficiently and at high speeds over long distances without needing multiple fibers. DWDM is essential for large-scale telecommunications and data centers, enabling vast amounts of information to travel quickly and reliably.
