Inline, Dome, or Hinged? How to Choose Your Fiber Joint Closure

Fiber joint closures are key in fiber optic networks. They protect and keep spliced fiber optic cables in good shape. It provides reliable IP68 waterproof sealing, durable mechanical protection, and organized fiber management for aerial, buried, and underground applications.

Fiber joint closure is a critical passive component that ensures the physical network remains robust and reliable, safeguarding the integrity of the data traveling through it.

Fiber Joint Closure-In-line type

Inline closures are slender, cylindrical enclosures designed primarily for protecting splices along a continuous fiber run. They are the go-to solution for straightforward, in-line splicing and branching.

Key advantage

1.Reliability: It provides a reliable sealing solution that maintains a secure grip for a long time.

2.Waterproof: It guarantees a waterproof seal to prevent moisture and potential water damage.

3.Easy to install: The installation process is relatively simple and only requires basic training for technicians.

4.Cost-effectiveness: The manufacturing cost is low compared to mechanical fiber closures.

Applications

✅ Fibre cable fusion splicing in pits, direct buried, aerial or pole mounting

✅ Fibre cable joining or repairs

✅ Fibre cable tap off and expressing

Fiber Joint Closure-Dome type

Dome closures feature a robust, dome-shaped design that provides maximum internal space and superior protection. These are the heavy-duty solutions for network aggregation points.

Key advantage

High quality PC, ABS, PPR material optional, can ensure harsh conditions such as vibration, impact, tensile cable distortion and strong temperature changes.

Solid structure, perfect outline, thunder, erosion and adding resistance.

Strong and reasonable structure with mechanical sealing structure, can be opened after sealing and cab be reused.

Well water and dust proof, unique grounding device to ensure the sealing performance, convenient for installation.

The splice closure has a wide application range, with good sealing performance, easy installation, produced with high strength engineering plastic housing, with anti-aging, corrosion resistance, high temperature and high mechanical strength and so on.

Applications

✅ Oil and Gas Industry

✅ Transportation and Logistics

✅ Retail and Commercial Spaces

✅ Marine and Coastal Facilities

✅ Security and Defense

✅ Public Infrastructure

Fiber Joint Closure-Hinged type

Hinged closures feature a unique clamshell design that opens completely, providing full access to the internal splicing area. These are designed for locations requiring frequent re-entry.

Key advantage

1.Complete, easy access to all internal components.

2.Dramatically reduced maintenance time-no need to dismount the entire closure for re-entry.

3.Excellent fiber management with organized tray systems.

Applications

✅Locations requiring frequent maintenance or upgrades

✅Street cabinets and distribution points

✅Any application where easy access is a priority
