The SPD Fiber Optic Terminal Box is a compact, durable enclosure designed for fiber splicing, splitting, distribution, and secure cable management in FTTH and FTTx networks.

Overview and Applications

The SP

D Fiber Optic Terminal Box, such as the SPD-16TM model, is used as a Fiber Distribution Point (FDP), Fiber Distribution Box (FDB), or Mini Fiber Distribution Cabinet (FDC). It serves as a central point for connecting and managing fiber optic cables, supporting up to 16 subscribers with one branching outlet, making it ideal for residential or small enterprise FTTH deployments. It integrates fiber splicing, splitting, distribution, storage, and cable connection in a single protective enclosure.

Key Features

Environmental Protection: Waterproof design meeting IP55 standards ensures reliable outdoor performance, while the sealant material prevents mold growth according to IEC 60068-2-10. Fiber Management: Supports fusion or mechanical splicing, maintains fibers at a safe bending radius, and allows efficient cable routing. Splitter Support: Can accommodate up to 5 splitters, including configurations like 1x16, 3x8, or 5x4, enabling flexible signal distribution.

Cable Ports: Equipped with 3 distribution cable ports with tap-out function and 16 separate drop cable ports, each fitting 2mm x 3mm drop cables and allowing SC connectors to pass through. Installation Flexibility: Supports aerial pole mounting with pole diameters from 100mm to 180mm, and can also be wall-mounted for indoor or outdoor use.

Construction and Materials

The SP

D terminal box is typically made from flame-retardant PC or ABS materials, providing mechanical strength, environmental stability, and low optical loss. Its compact design allows for neat fiber management in restricted spaces, ensuring clean and accurate signal transmission.

Benefits

Simplified Installation: Pre-configured ports and splitter support reduce setup time and maintenance effort. Network Reliability: Protects splices and connectors from dust, moisture, and physical damage, maintaining signal quality. Versatility: Compatible with various FTTH components, including ONUs, optical socket panels, and PON modules.

Summary

The SP

D Fiber Optic Terminal Box is a robust, versatile solution for fiber optic network distribution, offering high capacity, environmental protection, and efficient fiber management. It is suitable for both indoor and outdoor FTTH applications, providing secure, organized, and reliable connections for multiple subscribers. Its modular design and splitter compatibility make it a practical choice for expanding or maintaining fiber networks.
