A Fiber Access Terminal (FAT), also known as a Fiber Access Terminal Box (ATB) or Fiber Distribution Terminal (FDT), is a key component found in optimized fiber optic access networks for FTTH implementations. ⚡ The terminal box is the last structured node before the subscriber. Rack-mount (1U–3U, 12–48. In modern FTTH (Fiber to the Home) and optical communication networks, three types of fiber distribution products are widely used: Splitter Distribution Box, ODF (Optical Distribution Frame), and Fiber Terminal Box. Its primary function is to efficiently manage and terminate fiber optic cables, connecting the cable's core to a pigtail.
