Wave Division Multiplexing. Like FDD microwave. You have a single medium, aka shared path, air in the microwave case, a single fiber strand in the WDM case. Both are separate Tx and Rx frequencies/wavelengths. Both are full duplex. GigE over copper is another full-duplex bi-directional interface.

    What would the point of simplex be?

        I would be happy with a simplex, single fiber, that did 100mbps or
        1gbps if its SFP module with single SC connector that works with
        Mikrotik.
