Dome Type IP68 Fiber Optic Cable Joint Closure 48/96/144 Cores
Fiber Optic Cable Joint Closure (often called a splice closure or splice case) is a protective enclosure used to house and protect the spliced connection points of fiber optic cables. Its primary function is to provide a safe, sealed, and organized environment where two or more fiber optic cables can be joined, and the delicate fusion splices or mechanical splices can be stored and managed.

Material

Components
Housing/Shell: The main body, usually made of durable plastic (like PE, PP) or metal, designed to be mechanically robust.
Sealing System: Critical for water and dust-tightness. Common methods include:
Heat Shrink Seals: Used with cables that have heat-shrinkable sleeves
Mechanical Seals/Glands: Use clamps, rubber grommets, and sealing tapes to create a seal around the cable entries
Gel Seals: Often used with re-enterable closures
Cable Ports/Entries: Openings where the incoming and outgoing cables enter the closure. They are part of the sealing system.
Splice Tray (Organizer): The core internal component. It's a plastic tray that holds and protects the individual fusion splices (usually in silicone or gel sleeves) and manages the fiber routing. Multiple trays can often be stacked.
Mounting Bracket/Strand Hook: Allows the closure to be mounted on a pole, strand, tower, or placed in a manhole or handhole.
Installation
Aerial: Mounted on a support strand between poles
Underground/Burial: Placed in manholes, handholes, or directly buried
Pole-Mounted: Attached directly to a utility pole
Indoor: Used in controlled environments like data centers (less demanding sealing requirements)
Important Considerations
Cable Count and Fiber Count: Must accommodate the number of cables and fibers to be spliced
Re-enterability: Whether the closure needs to be reopened multiple times for network reconfiguration (common in access networks)
Sealing Method: Must be compatible with the cable types and installation method
Environmental Rating: Look for standards like IP68 (dust-tight and submersible) or GR-312 (Telcordia standard for outdoor closures)
Mounting Type: Must suit the physical location (pole, strand, etc.)
