Carrying multiple wavelengths on a single fiber is accomplished with Wave Division Multiplexing (WDM). This technique combines several optical signals, each at a different wavelength, onto one fiber so they travel together as separate channels. At the destination, a demultiplexer separates the wavelengths back into their individual data streams. This dramatically increases the fiber’s capacity without laying more fiber. The other terms don’t fit: Solid Metallic Conduit is just a protective pathway for electrical cables, not a signaling method for optics; a balun converts balanced to unbalanced signals and is used in RF contexts, not for multiplexing optical wavelengths; and system attenuation refers to signal loss rather than how multiple signals share the same fiber.
