Power Up: The ONT is powered on and initialized. Configuration: The tech will configure the ONT to work with your service provider's network and your home setup. A typical PON topology (GPON, XGS-PON, or 25G PON) flows OLT → fiber distribution hub → passive splitters → distribution/drop fibers → premises. The terminal box sits at the. FTTP or fiber To The Premises applications have reinforced the importance of reliable and stable fiber optic terminations. They also feature resistance to moisture, impact, chemical exposure. An Access Terminal Box (ATB), also known as a fiber access socket or fiber pizza box, is an indoor optical connection device used to link fiber drop cables with the optical distribution network (ODN). Although it may appear simple from the outside, this box plays a key role in ensuring fiber integrity, signal stability, and long-term.
