Fiber optic and Cat6 cabling are entirely different things. Fiber optic cables are what we discussed over the rest of the article, while Cat6 cables are ethernet cables that use twisted copper wires, specifically 4. Cat6 cables use the full capacity of the wire and can be more durable than fiber optic wires, requiring less maintenance.
Each will have its benefits and advantages, and we encourage you to look for a more detailed comparison if you are interested.
