Fiber Optic Terminal BoxLast-Mile Termination
Wall-mount and desktop terminal boxes for FTTH and indoor cabling — 4 to 24 ports with IP65 outdoor options.
Overview
A fiber optic terminal box — also called an FTB or fiber termination box — is the endpoint where incoming fiber cables are terminated, spliced, and connected to patch cords leading to user equipment. It is the critical last link in FTTH (Fiber to the Home), FTTB (Fiber to the Building), and enterprise fiber distribution systems. Choosing the right terminal box ensures clean fiber management, easy maintenance, and protection of delicate fiber splices.
TTI Fiber manufactures fiber optic terminal boxes in wall-mount, desktop, and pole-mount configurations with port counts from 4 to 24. Our indoor models feature ABS or cold-rolled steel construction with integrated splice trays, bend-radius-compliant fiber routing, and snap-in SC or LC adapter panels. For outdoor applications, our IP65-rated terminal boxes use UV-resistant ABS housings with rubber gasket seals, making them suitable for building exteriors and utility poles.
All terminal boxes are designed for tool-free fiber access and come pre-configured or as empty enclosures ready for field installation. As an ISO 9001 certified manufacturer with over 15 years of experience, TTI Fiber offers OEM customization, bulk pricing, and worldwide shipping for telecom operators, ISPs, and FTTH project contractors.
