FTTH Terminal Boxs
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 fiber cabling and cable management.
Fiber Distribution Boxes (FDBs) are known by several other names too , depending on the specific application and location. Some of the other names used for FDBs include:
- Fiber Termination Box (FTB)
- Fiber Access Terminal (FAT)
- Optical Network Terminal (ONT)
- Fiber Distribution Hub (FDH)
- Fiber Demarcation Point (FDP)
- Fiber Enclosure
- Fiber Optic Splice Closure (FOSC)
These terms are often used interchangeably, but they may have slightly different meanings depending on the context. For example, an ONT is typically used specifically in FTTH networks to provide a connection point for a single customer, while an FDH is typically used in larger networks to distribute fiber optic signals to multiple customers or buildings.
FTTH Terminal Box Fiber Optic Distribution Box Fiber to the home (FTTH) infrastructures make network organizers adopt powerful management and planning systems, FTTH termination box and Fiber Optic Distribution Box is a small part of this system and provides a cost-effective solution for FTTH applications.
FTTH Terminal Boxs

Overview
The FTTH Terminal Box serves as a compact fiber termination enclosure for residential and enterprise optical networks. It safeguards splicing points and connectors, ensuring clean and accurate signal transmission in Fiber‑to‑the‑Home (FTTH) projects. Designed for wall‑mounting or pole installation, each unit allows neat fiber management within restricted spaces.
This category covers a broad range of models from 2‑port up to 16‑port capacity. Manufactured from flame‑retardant PC or ABS material, these boxes comply with ITU‑T and IEC standards, offering reliable mechanical protection and minimal optical loss.
Key Features
- SC, LC, FC adapter compatibility for flexible fiber interface setups
- Accommodates both fusion splice and mechanical splice protection
- Indoor and outdoor‑rated versions for versatile deployment
- IP‑rated sealing for dust and moisture protection
- Various entry options for drop cables and pigtails
- Compact design ensures ease of installation on wall or pole brackets
- Cable bending radius control reduces signal attenuation
- Available capacity from 2 cores to 16 cores
Applications
The FTTH terminal box series is widely used in fiber access networks, distribution points, and telecom building entrances. It provides secure connection for ONU, Optical Socket Panels, and customer end faces in FTTH systems.
