Outdoor 2 inlet 2 out Fiber Optic Joint Closure 144 Cores Solutions
A Fiber Optical Closure is used for the outdoor connection between optical distribution cable and optical in room cable. Our Fiber Optical Splice Junction Box is available for aerial, duct, direct buried application, it is connected to optical switch through optical fiber jumper to prevent material aging caused by heat, cold, light, oxygen and microorganisms in nature. It also has excellent mechanical strength. The solid shell and main structure of optical cable junction box can endure the worst environmental changes, and play a flame retardant role at the same time. Waterproof effect, so that vibration, impact, cable tension, twist and so on are protected.

Application:
1.1 Underground Installation
They are designed to resist moisture, soil pressure, and corrosion, ensuring stable fiber connections in direct-buried optical cable projects.
1.2 Aerial Installation
Lightweight and wind-resistant, they are mounted on utility poles to connect aerial optical cables, with excellent sealing to withstand rain, snow, and UV radiation.
1.3 Duct Installation
Fitted in underground ducts, they accommodate fiber splicing and management while preventing dust and moisture intrusion.
1.4 Indoor/Outdoor Transition
Used at the junction of indoor and outdoor optical cables to protect the connection point from environmental changes and mechanical damage.
1.5 Fiber Distribution Points
Serve as intermediate nodes in FTTH (Fiber to the Home) networks, enabling fiber branching and connection for end-user access.
