144Core Fiber Optic Dome Splice Closure

Manufactured by Ningbo Yuanyi, a specialized 144Core Fiber Optic Dome Splice Closure manufacturer with years of experience in the fiber optic industry.

The MS09 144Core Fiber Optic Dome Splice Closure uses a mechanical sealing structure with integrated rubber sealing rings to provide reliable protection without adhesives or sealing tapes. An integrated air valve allows sealing performance to be tested after installation, helping technicians verify enclosure integrity in the field.

With an IP68 protection rating, corrosion-resistant ABS/PP housing, and support for both ribbon and conventional fiber optic cables, this closure is suitable for demanding outdoor environments and long-term network maintenance.

Specifications

Mechanical Sealing Design

The MS09 144Core Fiber Optic Dome Splice Closure adopts a mechanical sealing system rather than adhesive-based sealing. Elastic rubber sealing rings are used to create a secure enclosure around the cable entry points and housing interface.

The closure can be reopened for fiber inspection, maintenance, or re-splicing and then resealed without replacing the entire enclosure. The integrated air valve provides a convenient method for checking the sealing condition after assembly.

Installation Applications

The 144Core Fiber Optic Dome Splice Closure is suitable for:

· Aerial fiber optic cable networks

· Underground duct and pipeline installations

· Telecom manholes

· Direct-buried fiber optic networks

· FTTH and FTTx infrastructure

· Fiber distribution and cable branching points

· Outdoor telecom and communication networks

· Network expansion and maintenance projects
