Special-Type Optical Cable Splice Closure

Product Overview

The Special-Type Fiber Optic Splice Closure is an integrated outdoor protection device for straight-through, branch, and splitter distribution, with a housing molded as a single piece from modified polymer plastic that is flame-retardant and impact-resistant. Combined with a non-vulcanized self-adhesive rubber mechanical seal, it achieves a high IP68 protection rating, blocking out temperature fluctuations, rain, UV radiation, and microbial erosion, and resisting damage to fiber splice points from vibration and cable tension/torsion. It features a combination cable port layout with multiple specifications, including 1 straight-through port, 2 branch ports, and 6 outlet ports, accommodating cables of varying thickness as well as drop cables. Internally, it houses 12 independent flip-open 12-fiber trays for a total capacity of 144 fibers, with each tray independently hinged so maintenance on one does not affect others, and supports cross-tray fiber routing; a mounting slot for a miniature splitter is reserved inside the box. The overall screw-free, flip-open structure allows convenient assembly and disassembly, and it supports both wall-mounted and pole-mounted installation, making it widely used in community FTTH and trunk cable branch distribution projects.

Key Advantages

Multi-Specification Composite Cable Ports

Multi-channel combination cable ports, compatible with both thick cables and thin drop cables, offering broader cabling compatibility.

144-core high capacity

12 fiber trays with 12 fibers each, for a total capacity of 144 fibers, meeting the needs of centralized multi-link fiber splicing.

Independent Flip-Open Fiber Trays

Each tray is independently hinged and flips open separately, so operating one tray does not disturb the fibers in others, and cross-tray splicing is supported.

Screw-Free Flip-Open Structure

Screw-free flip-open design allows the seal to be reopened repeatedly and supports the addition of a miniature splitter.
