Optical Cable Splice Closure

Product Overview

This fiber optic splice closure is a comprehensive outdoor protection device used for straight-through splicing, branching, splitting, and adapter distribution. The box body is molded as a single piece from modified polymer plastic, offering flame-retardant, impact-resistant, and weather-resistant properties. Combined with a non-vulcanized self-adhesive rubber mechanical seal, it achieves an IP68 protection rating, resisting rain, high and low temperatures, and UV erosion, and cushioning fiber splice points against damage from impact and cable tension/torsion. It is equipped with 1 straight-through port and 2 branch ports, compatible with Φ10-17.5mm cables. Internally, it houses 12 independently hinged 12-fiber trays for a total capacity of 144 fibers, with each tray flipping open independently without disturbing others, and supports cross-tray fiber routing. The box reserves 8 outdoor adapter mounting slots and space for a miniature splitter, integrating splicing, splitting, and distribution functions. The overall screw-free, flip-open structure allows convenient assembly, disassembly, and repeated resealing. It comes standard with a wall-mounting kit and supports pole mounting, and is widely used in community FTTH and trunk cable branch distribution projects.
