The SPB Series FTTH Drop Cable Splicing Protective Box is a compact and robust indoor enclosure designed to provide secure fiber splicing and termination for 1 to 2 FTTH subscriber drop cables. Serving as a transition point between the drop cable and the pigtail leading to the ONT (Optical Network Terminal), this box ensures a clean and protected fiber connection in residential and small-scale installations.

Constructed from industrial-grade ABS PBT-V0 flame-retardant materials, the SPB enclosure offers high durability and fire safety compliance. It integrates the fiber splice sleeve within a sealed, dust-proof housing (IP45 rating), protecting it from damage and environmental exposure.

Its embedded surface design and wall-mountable format enable quick installation and removal without special tools. With flexible input/output ports, the SPB box supports both drop cables and pigtails (45–60mm splice sleeves), making it a practical choice for FTTH deployments that require reliability, safety, and scalability.

Ideal for use in multi-dwelling units (MDUs), small homes, and ONT access points, this protective box streamlines fiber distribution while maintaining network performance.
