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.

Specification:

Components:

1.1 Housing/Shell: The main body, usually made of durable plastic (like PE, PP) or metal, designed to be mechanically robust.

1.2 Sealing System: Critical for water and dust-tightness. Common methods include: Heat Shrink Seals: Used with cables that have heat-shrinkable sleeves.

1.3 Mechanical Seals/Glands: Use clamps, rubber grommets, and sealing tapes to create a seal around the cable entries.

1.4 Gel Seals: Often used with re-enterable closures.

1.5 Cable Ports/Entries: Openings where the incoming and outgoing cables enter the closure. They are part of the sealing system.

1.6 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.

1.7 Mounting Bracket/Strand Hook: Allows the closure to be mounted on a pole, strand, tower, or placed in a manhole or handhole.

Installation:
2.1 Aerial: Mounted on a support strand between poles.

2.2 Underground/Burial: Placed in manholes, handholes, or directly buried.

2.3 Pole-Mounted: Attached directly to a utility pole.

2.4 Indoor: Used in controlled environments like data centers (less demanding sealing requirements).

Noted:

3.1 Cable Count and Fiber Count: Must accommodate the number of cables and fibers to be spliced.

3.2 Re-enterability: Whether the closure needs to be reopened multiple times for network reconfiguration (common in access networks).

3.3 Sealing Method: Must be compatible with the cable types and installation method.

3.4 Environmental Rating: Look for standards like IP68 (dust-tight and submersible) or GR-312 (Telcordia standard for outdoor closures).

3.5 Mounting Type: Must suit the physical location (pole, strand, etc.).
