ATB connects the fiber optic cable that is connected to the outside of your home to your modem.
The ATB is a small white plastic box (180mm x 50mm x 120mm) that fits on your interior wall.
It is very important to know where to install the ATB (Access Terminal Box) before starting a fiber optic installation project, as this can affect your broadband experience. Your modem connects to your ATB, so it must be installed in a very suitable place—where you use the internet the most.
ATB or OTO is a box or box installed at the user’s premises and terminates the Passive Optical Network (PON).
