Dome Type Fiber Optic Splice Closure 288 Cores

Dome Type Fiber Optic Splice Closure 288 Cores

Fiber optic splice closure is widely applied to the splicing, distributing variable optical cables and splitting. The solid box shell and the main structure can endure harsh environment.It protect the fiber optic cable from vibration,impact,stretches,twists. The closure can work in -35ºC~70ºC environment,cold and heat resistance,electrical insulation,chemical corrosion resistance.

Description

Product Information

A fiber optic splice closure serves as an enclosure that protects fiber splices from environmental damage, moisture ingress, and mechanical stress. The dome-shaped design offers:

Enhanced structural integrity under heavy loads

Ample tray space for high-density splicing

Quick access for re-entry and maintenance

With support for up to 288 cores, this dome-type closure addresses the needs of large-scale Fiber-to-the-Home (FTTH) projects, data center interconnects, and backbone networks.

Accommodates 12 splice trays, each holding 24 splices

Perfect for urban backbone and multi-drop FTTH topologies

IP68-Rated Sealing:

Fully dust-tight and waterproof

Suitable for underground duct banks, direct burial, or aerial attachments

Durable Dome Housing:

UV-stabilized, corrosion-resistant polymer construction

Crush resistance up to 1600 kg

Flexible Cable Entry Ports:

Supports multiple cable diameters: 7 mm–32 mm

Universal round and oval ports, easily customized on site

Quick Assembly & Re-Entry:

Tool-free dome clamps with wedge locks

Re-entry kits ensure fast field maintenance without compromising sealing

Universal Compatibility:

Works with loose tube, ribbon fiber, and armored cable designs

Adaptable mounting options: pole, wall, and strand
