    I totally get how this would be useful in imaging systems, but I’m not understanding how it applies to communications.

    The only thing I can think is perhaps carrying more modes through a multimode fiber? I never understood amplifier bandwidth to be a limiting factor, though.

    What communications systems use a wide bandwidth of light (300nm is a LOT) into a single amplifier?

      That’s a great question. My guess is the bandwidth comes from bonding those extra modes and from the lower signal-noise ratio. That lower SNR means they could modulate with more sensitive but faster modes.
