How many ports does the fiber optic terminal box use

A fiber optic terminal box can have up to 48 ports.

Fiber optic terminal boxes, also known as FTBs or fiber termination boxes, are used to terminate, splice, and manage fiber optic cables at the network edge. The maximum number of ports depends on the type and deployment scenario: Rack-Mount Boxes: Typically designed for high-density applications in telecom rooms or multi-dwelling units, these can support 12 to 48 ports depending on the rack size (1U–3U) and configuration . Wall-Mount and Desktop Boxes: Common for apartments, offices, or small indoor installations, these usually support 4 to 24 ports, with some outdoor IP65-rated models also falling within this range . Outdoor and High-Density Boxes: Specialized outdoor enclosures or high-capacity FTTx nodes can accommodate up to 48 ports, often including multiple splice trays and organized fiber routing to maintain serviceability and minimize loss . Each port typically accommodates one SC simplex or LC duplex adapter, and the boxes are designed to protect fibers from environmental factors, maintain bend radius compliance, and allow easy access for maintenance. High-port boxes are particularly useful in scenarios requiring dense fiber termination, such as service-provider nodes, FTTH access hubs, or large enterprise networks .
