Fiber Optic Vs WIFI?

There is a difference between fiber optics and WIFI

Fiber optics is a fiber made of glass or plastic that acts as a light transmission tool.
Optical fibers are composed of two layers of glass with different refractive indices. The inner layer is the inner core of light, with a diameter of a few microns to tens of microns, and the outer layer has a diameter of 0.1 to 0.2 mm. generally the refractive index of the inner core glass is 1% larger than that of the outer glass. According to the principle of refraction and total reflection of light, when the angle between the inner core and the outer layer is greater than the critical angle of total reflection, the light does not pass through the interface, all reflected.

WIFI is a wireless transmission network! Fiber optic, just a medium used for network lines, and not wifi, the two are not linked, wifi is just the device face network after the wireless signal is emitted through other devices, and then other devices to access the Internet.
Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), usually using the 2.4G UHF or 5G SHF ISM radio frequency band. Connection to a WLAN is usually password-protected; however, it can also be open, allowing any device in range of the WLAN to connect. Wi-Fi is a brand of wireless network communication technology, held by the Wi-Fi Alliance.
