This is a stupid question. Assume you have a laser going 1 meter straight forward. You then refract the laser through twisted fiber optic cable or through a bunch of mirrors or something such that it travels the same net meter, but over a longer path. Relativity doesn't imply that it would take the same amount of time to travel that net meter right? It's still longer route = longer time? It's just observer speed that causes relativistic effects?

Yes, it would take a longer time. If I bounce a laser to the moon and then to one meter in front of me, it still travels a "net meter" - just over a much, much longer path, therefore taking longer.
