    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.
