The GPON network is based on the principle of Point to Multipoint, that is, the distribution of the signal from a central point to multiple users.
How to work in a nutshell:
1️⃣ OLT (Optical Line Terminal):
Located in the central, it sends the light signal through fibers.
2️⃣ Splitter:
Distributes the signal to several subscribers without the need for electricity ⚡
3️⃣ ONT (Optical Network Terminal):
A device in the user's home that receives the signal and converts it to the Internet, TV or telephone ??
? Downstream: from OLT to all users ?
? Upstream: From users to OLT using time regulation (TDM) ⏱️
Imagine it as a water network that branches off from the source and delivers service to every home! ??
