Fiber Optic Splice Closure
Reliable protection for your fiber joints — YingFeng’s splice closures are engineered for long-term outdoor and indoor use, offering dust-proof, water-tight and anti-corrosion protection for aerial, underground and inline fiber splices.
Durable Splice Closures for Every Network Need
YingFeng offers a full range of fiber optic splice closures — dome, inline, horizontal and aerial types — designed to protect fiber splices in FTTH, FTTx, access networks and backbone deployments. Our closures provide stable mechanical strength, IP-rated sealing, and clear cable management for up to multiple core splices, compatible with heat-shrink, mechanical and fusion splice trays.
Outdoor Aerial & Underground Protection
Designed for harsh outdoor environments, our aerial and underground splice closures resist moisture, salt spray and extreme temperatures. Ideal for pole-mounted aerial runs, duct/handhole installations and buried feeder lines — they keep fiber splices secure and minimize network downtime.
Inline & Drop Splice Solutions for Access Networks
Inline and horizontal splice closures are perfect for compact runs, service drops and access aggregation points. Their compact footprint and easy cable entry make them suitable for tight spaces, street-level cabinets and last-mile distribution where reliable, flexible splice management is required.

FAQ
What are the differences between dome and horizontal fiber optic splice closures?
Dome Fiber Optic Splice Closure: A common design with a dome-shaped top, ideal for large-scale outdoor applications where multiple fibers need to be spliced. It typically offers easy installation and high capacity for fiber storage.
Horizontal Fiber Optic Splice Closure: Features a more compact, horizontally oriented design, often used in tight spaces or for specific outdoor installations that require a low-profile setup.
What does IP68 splice closure mean, and why is it important?
An IP68 splice closure refers to a splice box with a high level of protection against dust and water. The “6” indicates complete dust protection, while the “8” signifies its ability to withstand submersion in water. This rating is crucial for outdoor fiber optic installations, ensuring the splice closure remains intact and operational even under extreme environmental conditions.
