Over the last few weeks, I've been sharing a deep dive into the world of optical networking and Dense Wavelength Division Multiplexing (DWDM). This technology is the backbone of modern data communication, enabling the ultra-fast, high-capacity networks that power our digital lives. Instead of transmitting one signal per fiber, WDM systems combine multiple optical carriers. SONET TDM takes synchronous and asynchronous signals and multiplexes them to a single higher bit rate for transmission at a single wavelength over fiber. Source signals may have to be converted from electrical to optical, or from optical to electrical and back to optical before being multiplexed.
