Fiber Optic Dome Enclosures
Model:GL-M9/JFT-BS Fiber Optic Dome Enclosures
High-performance fiber splice enclosure for demanding outdoor and underground environments,Compact yet high-capacity fiber splice enclosure designed for FTTH, FTTx, backbone, and distribution networks
- Product Introduction
The GL-M9/JFT-BS Dome Closure from Glory Optical Communication is a robust and versatile solution for protecting optical fiber connections in harsh outdoor and underground environments. Engineered with precision, this dome-type mechanical seal closure offers exceptional durability and flexibility for modern network infrastructure.
With its IP68-rated sealing and compact design (Φ330 × 390 mm), this enclosure provides reliable protection against water, dust, and mechanical stress while accommodating up to 432 fiber cores. The innovative stacked tray design and support for SC simplex and duplex adapters make it an ideal choice for both new deployments and network upgrades.
Whether deployed in FTTH distribution nodes, access point fiber joints, or harsh weather areas requiring waterproof protection, the GL-M9/JFT-BS ensures secure joint protection, convenient installation, and flexible capacity expansion.
Key Features
Designed for performance, durability, and flexibility in demanding environments
High Capacity Design
Despite its compact size, the closure supports multiple splice tray types and can accommodate up to 432 fiber cores in the SC16 model, making it ideal for space-constrained deployment sites.
IP68 Protection
Constructed with high-strength engineering plastic, the enclosure provides excellent resistance to mechanical stress, UV, corrosion, and aging, with IP68 rating ensuring reliable waterproof and dustproof performance.
Flexible Port Configuration
With a total of 9 cable ports (1 oval + 8 circular) compatible with cable diameters from 7mm to 26mm, the closure offers versatile installation options for loop-through or mid-span branching.
Adapter Integration
Supports SC simplex adapters (up to 17 pcs in SC16 model) and SC duplex adapters (up to 33 pcs in 2SC32 model), with integrated slots for PLC splitters ideal for GPON/EPON access deployments.
Mechanical Seal Design
No heat shrink required - mechanical sealing via threaded locking ensures easy installation, maintenance, and re-sealing while maintaining tight seal under temperature changes and vibrations.
Safety & Grounding
Built-in independent insulation grounding system enhances operator safety and fiber protection, simplifying ground wire management during cable entry.
