Dual-End Optical Cable Splice Closure

Product Overview

The Dual-End Fiber Optic Cable Closure, also known as a fiber optic splice closure, is a dedicated protective device for cable jointing and branch splicing in fiber optic communication lines. Its high-strength polymer housing offers excellent mechanical strength, resisting temperature fluctuations, UV radiation, moisture, and microbial erosion, while also being flame-retardant and waterproof, cushioning damage from vibration, impact, and cable tension/torsion to fully protect internal fiber splice points. It features a 4-port layout with 2 inlets and 2 outlets, is compatible with Φ10 to 18mm cables, and can hold up to 3 trays of 24-fiber splice trays for a maximum capacity of 72 fibers. It is compatible with aerial, duct, and direct-buried deployment scenarios, meeting the needs of straight-through and branch splicing installations.

Key Advantages

Screwless latch fastening allows repeated disassembly and maintenance

The box body features a screw-free latch structure on all sides, requiring no tools to open or close. The box can be opened repeatedly for fiber line maintenance and expansion, making subsequent operation and maintenance simple and efficient.

Mechanical sealing provides all-weather waterproof protection

Combined with non-vulcanized self-adhesive rubber seals and an overall mechanical sealing structure, with cables sealed via nut compression, it provides dust resistance, waterproofing, and aging resistance, suitable for complex outdoor high- and low-temperature environments.

Split Cable Port Design with Broad Cable Compatibility

Features 4 cable ports (2 inlets and 2 outlets) with detachable sealing nuts, compatible with various cables in the Φ10 to 18mm range. Adding or removing cables does not require replacing the entire sealing accessory set, offering greater practicality.

Multi-Scenario Adaptability with Complete Accessories

Comes standard with a wall-mounting kit, with optional aerial mounting hardware and an inflation valve available. It supports the two mainstream installation methods of aerial and duct deployment, making it suitable for the vast majority of outdoor communication line construction.
