Fiber Optic Distribution Box (FDB) / Fiber access terminal box (FAT) / optical termination box (OTB) / Fiber termination box (FTB) / Optical Distribution box (ODB) are a compact fiber management box used for FTTH application. is widely used in FTTx cabling for both. A fiber optic distribution box — also known as an FDB or NAP (Network Access Point) — is a mid-span enclosure that distributes fibers from a feeder cable to individual drop cables serving subscribers or building floors. It typically contains splice trays, adapters, and cable routing components to manage fiber connections. The “IP68” designation means that the box is both completely dust-tight and waterproof for long-term submersion, according to IEC 60529 standards. Understanding how these devices work together helps.
