As a photonics engineer, I'm more impressed by the 55-mode fibre than anything else

I'm not an engineer when it comes to photonics, just curious, and I didn't even know this would be stable enough to work with.

Can you explain what that means to someone not deeply familiar with networking?

Can you explain what multi-mode fibres are? From what I've read, it allows for WDM over a single fibre. But what is physically different about these multimode fibres that allow for this Space-division multiplexing? Wikipedia says:
>Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion.[0]
But that's clearly wrong because here we are using the standard diameter.
