Protect, manage, splice and distribute your fiber infrastructure with YINGDA’s high-performance Fiber Optic Splice Closures. From high-density 576-core backbone dome closures (IP68 certified) to last-mile FTTH distribution closures (IP65 rated) featuring built-in PLC splitters and SC adapters, we deliver reliable sealing protection tailored to every network layer. Fully compliant with international telecom standards, our products ensure zero-attenuation connectivity for global ISPs and network contractors.
High-Density Backbone & Underground Protection
Optimized for harsh environments like underground manholes, handholes, and aerial poles. Its robust dome design features heavy-duty mechanical or heat-shrink seals to isolate high-count fibers from high water pressure.
• Capacity: Up to 576 Cores
• Sealing Rating: IP68 Certified
• Testing: Official Report Available
Versatile Sealing for Straight-Through Networks
Ideal for shallow trenches, wall-mounting, or aerial strand deployments. Utilizing reusable gel or silicone sealing gaskets, it provides an outstanding balance of rigorous protection and effortless network re-entry.
• Capacity: Up to 288 Cores
• Sealing Rating: IP68 Certified
• Re-entry: Toolless / Reusable
All-in-One Splitting & Patching for Last-Mile Access
Specifically engineered for outdoor building facades and wall-mount subscriber connections. Designed with dedicated space for built-in PLC splitters and SC adapters, this enclosure transforms traditional splice boxes into smart terminal hubs, speeding up subscriber turn-up times.
• Integration: PLC Splitter & SC Adapters
• Sealing Rating: IP65 Weatherproof
• Application: Aerial / Wall / Pole Mount

We don’t over-promise; we deliver exact engineering. Our trunk-line closures hold official IP68 test reports for continuous underwater submersion, while our last-mile FTTH boxes feature a durable IP65 weatherproof design perfect for outdoor wall installations.
Our IP65 FTTH closures support the seamless installation of 1×4, 1×8, or 1×16 PLC splitters alongside SC adapters. Technicians can house splitting, fusion splicing, and patch cabling in one compact box, slashing field deployment costs.
Accommodates flexible network expansions from 12 up to 576 cores. Multi-layer, independent splice trays protect the fiber bend radius and simplify routing even when fully loaded.
Molded from premium, impact-resistant PP, ABS, or PC plastics blended with advanced UV inhibitors. Built to withstand heavy UV exposure and extreme temperatures (-40°C to +65°C) without cracking or degrading.
Yingda provides factory-direct pricing, scalable production, and full technical documentation for compliance approval.
This is aligned with international telecom standards based on deployment environments. Vertical (Dome) closures are often buried or placed in manholes where they face the risk of long-term submersion, requiring an IP68 rating. FTTH distribution boxes are typically mounted on outdoor walls or under eaves where they face rain and dust but not immersion, making an IP65 rating the industry-standard, cost-efficient solution.
Our FTTH closures are equipped with flexible internal brackets that can securely house blockless or cassette-type PLC splitters (such as 1x4, 1x8, and 1x16)along with corresponding SC/APC or SC/UPC adapters for plug-and-play user drop cable connection.
Yes. We provide official IP68 test reports issued by accredited independent laboratories to support your technical evaluation and bidding processes.
Dome (vertical) joint closures utilize a single-ended base where all cable ports exit from the bottom, offering superior watertight integrity for vertical underground manholes and pole hanging. Inline (horizontal) closures feature cable entry/exit ports on opposite sides, utilizing a flat-profile design that slides effortlessly into narrow horizontal conduits or shallow trenches.
Yes. Our specialized FTTH splice closures are engineered with integrated inner split-level architecture. They feature dedicated lower brackets designed to snap-in mini PLC splitters or unbalanced couplers, while the upper layer manages the fiber fusion splice trays, allowing seamless drop-cable branching right inside a sealed IP68 node.
We wholesale both variations to match local utility specifications. Our mechanical seal closures utilize premium silicone rubber gaskets with reusable tension screws, perfect for networks requiring frequent re-entry and expansion. Our heat-shrink seal closures utilize thermo-stabilized adhesive sleeves, providing a permanent, ultra-secure seal against harsh gas and chemical seepage in subterranean ducts.
