Wavelength Division Multiplexing (WDM) is the “prism” of fiber optics. It allows you to send multiple data streams over a single strand of fiber by giving each one its own “color” (wavelength). The variations (CWDM, DWDM, LWDM, and the likely intended FWDM) exist because of a fundamental engineering tradeoff: How much data can you pack…
