Question

what the different of fiber optic and 4G

Answer 1

Compared to the average ADSL Internet speed, more often than not the download speeds are actually a little better on 4G, as you can see in this comparative screenshot from BT's fixed-line broadband. However, if you're on a fibre-optic broadbandconnection, you can get anything up to 100Mbps.

Answer 2

Basic cable internet speeds range from 6 Mbps to 18 Mbps, while more advanced cable internet can reach speeds of 75 Mbps and even higher. However, Cable Internet speeds can be affected by users within the same vicinity using the same cable connection. The more people, the slower the rate.
