Is there any speed difference if we replace a 200-300 meters of copper cables with optical fiber cables? Whats the reason if it increases?

Fiber cables have higher data transfer speed not because light travels faster in a fiber than electromagnetic waves in a copper wire, but because they can be modulated by signals having far higher ...

Is there any speed difference if we replace a 200-300 meters of copper cables with optical fiber cables? Whats the reason if it increases?

Niels Nielsen's answer is correct. Just to provide some calculations as to actual propagation speeds (not signal bandwidth): Typical optical fibers have $n\approxeq 1.5$ , so the propagation speed is ...

Could we theoretically use much lower frequencies for fiber optic transmission?

Shorter wavelengths get you into the microwave regime, i.e. use air or vacuum for the "fiber core." Back to optical comms, then: Much of the design parameter space does depend on available ...

Could we theoretically use much lower frequencies for fiber optic transmission?

You want both a laser that is easy to make and a material that can transmit that laser with low losses (transparent) and is also easy to make. Also, for a gut feeling, 1THz is starting to become like ...

LAN data from computer

As stated by @NMech, I would suggest using a sniffer. I am assuming your connections are something like the following. I would use wireshark which a very popular open source tool used by network ...

What emits more radiation, cell network or wifi?

So, after a little googling around. Cellphones typically transmit on 3/4 G at between 0.3 and 3 W - subject to tower location & interference. The out put power is managed by the cell tower. ...
