Fiber optic cable is consists of optical fiber and provides a very fast way of communicating data at a relatively small cost. It's main advantages is that it's fast, reliable and it can carry data over long distances without being affected by electro-magnetic interference.

WiFi is a way of transferring data without any cables at all, wirelessly. Compared to fiber optic it is very slow and less reliable. Also, since there is no cable involved, it is also considerably more risky from a security perspective, as communications can be easier to intercept than in the case of fiber optic, where sophisticated equipment would need to be employed and the cable itself physically pierced for eavesdropping to succeed.

So fiber optic is better, if given the choice and without regard to cost.

Can you use a fiber optic cable from DVD player to tv?

I sold this stuff for 12 years and never plugged a fibre optic cable into a TV. This should be plugged into your amplifier for your surround sound. (typically) You will not be able to tell the difference between that or a simple audio cable through a TV.
