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.
I wanna know if I can plug my guitar into it
