My talk about wavelength division multiplexing (WDM) on optical fiber

I gave a talk at PhreakNIC 24 about wavelength division multiplexing. I’m far from an expert myself, but I know enough to work with the technology, understand how cool it is, and want to share that knowledge with others. If you’d like to take a look, the talk was recorded, so here’s the video. Or you can take a look a the slides.
