Regular people don't know whether to get Cat5, Cat5e, Cat6, or Cat7.

I can query Google, an LLM, or a run of the mill cancer doctor for information on how to treat my stage 1 melanoma. That I can learn how to treat stage 1 melanoma doesn't mean that I know how to treat stage 1 melanoma.

> [Fiber optics are so complicated.] [With copper, all] you need to know is the speed and perhaps the length although I think only "the 1%" will need more than 55 meters :-)

For a 55 meter run, all you need to know is "Buy the cheapest multimode two-strand fiber your vendor has in stock. It's going to have LC ends, so get LC multimode optics.". You don't even have to worry about the speed of the transceivers to use this advice.

As an aside: Wow. That's [0] pricey for a dumbswitch that you also can't ever switch over to fiber. You can get a managed switch with four 10gbit cages, five 1gbit cages, and one 1gbit port for fifty bucks less [1], or a (physically much smaller) managed switch with four 10gbit cages and one 1gbit port for about the same price as that five-port TP-Link dumbswitch.

TP-Link is absolutely raking in the dough on that unit.
