The cost-effective, compact, and energy-efficient amplifier boasts a bandwidth of 300 nanometers, enabling it to transmit ten times more data per second.

    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?

    Is 300 nm the diameter of the optical cable? This terminology breaks my brain, 300 nm is 1000 terahertz, which is unreasonably large for a signal bandwidth, it’s like one milllion Ethernet cables.

      I’m only making assumptions, but I’d guess that 300nm is the range of frequencies it can amplify. AFAIK fibre cables are used with multiple “channels” by sending data with different frequencies at once. Say your signal range is centered around 850nm, this amplifier could amplify in the range of 700-1000nm.

      But I might be totally off, just guessing.
