AFAIK most optical cables are made in the same factory so it doesn't matter which one you buy. They also don't need controlled impedance like copper cables so it's pretty hard for an optical cable to not work
So buying that second option (the Lindy link) is really just wasting hundreds of pounds with zero benefit, apart from shipping speed, compared to the cheap AliExpress option?
FWIW, a 10m 5gbps optical USB cable is $70 in the US including 1-day shipping. Dunno why anyone would pay hundreds of pounds even with the euro/pound tax.
Normally you'd buy optics and fiber (which is cheaper than copper ethernet cables of the same length) separately for data center use and in larger volume, but my point is that there's no expensive tech involved in these cables.
