OYI-FOSC-H8
Fiber Optic Splice Closure Heat Shrink Type Dome Closure
OYI-FOSC-H8
The closure has 5 entrance ports on the end (6 round ports and 1 oval port). The shell of the product is made from PP+ABS material. The shell and the base are sealed by pressing the silicone rubber with the allocated clamp. The entry ports are sealed by heat-shrinkable tubes. The closures can be opened again after being sealed and reused without changing the sealing material.
The closure's main construction includes the box, splicing, and it can be configured with adapters and optical splitters.
Product Features
High-quality PP+ABS materials are optional, which can ensure harsh conditions such as vibration and impact.
Structural parts are made of high-quality stainless steel, providing high strength and corrosion resistance, making them suitable for various environments.
The structure is strong and reasonable, with a heat shrinkable sealing structure that can be opened and reused after sealing.
It is well water and dust-proof, with a unique grounding device to ensure sealing performance and convenient installation.The protection grade reaches IP68.
The splice closure has a wide application range, with good sealing performance and easy installation. It is produced with high-strength engineering plastic housing that is anti-aging, corrosion-resistant, high-temperature resistant, and has high mechanical strength.
The box has multiple reuse and expansion functions, allowing it to accommodate various core cables.
The splice trays inside the closure are turn-able like booklets and have adequate curvature radius and space for winding optical fiber, ensuring a curvature radius of 40mm for optical winding.
Each optical cable and fiber can be operated individually.
Sealed silicone rubber and sealing clay are used for reliable sealing and convenient operation during the opening of the pressure seal.
The closure is of small volume, big capacity, and convenient maintenance. The elastic rubber seal rings inside the closure have good sealing and sweat-proof performance. The casing can be opened repeatedly without any air leakage. No special tools are required. The operation is easy and simple. An air valve is provided for the closure and is used to check the sealing performance.
Designed for FTTH with adapter if needed.

OYI-FOSC H13
The OYI-FOSC-05H Horizontal fiber optic splice closure has two connection ways: direct connection and splitting connection. They are applicable to situations such as overhead, manhole of pipeline, and embedded situations, etc. Comparing with a terminal box, the closure requires much stricter requirements for sealing. Optical splice closures are used to distribute, splice, and store the outdoor optical cables that enter and exit from the ends of the closure. The closure has 3 entrance ports and 3 output ports. The shell of the product is made from ABS/PC+PP material. These closures provide excellent protection for fiber optic joints from outdoor environments such as UV, water, and weather, with leak-proof sealing and IP68 protection. -
Direct Bury (DB) 7-way 16/12mm
A bundle of micro/mini-tubes with strengthened walls is encapsulated in a single thin HDPE sheath, enabling seamless retrofitting into existing duct infrastructures for cost-efficient fiber optical cable deployment. Optimized for high-performance air-blowing, the micro ducts feature low-friction inner surfaces that accelerate fiber optical cable installation—critical for FTTH networks, 5G backhaul systems, and metro access networks. Color-coded per Figure 1, the ducts support organized routing of multi-service fibers (e.g., DCI, smart grid), enhancing network scalability and maintenance efficiency in next-gen optical infrastructures. -
OPGW Optical Ground Wire
The central tube OPGW is made of stainless steel (aluminum pipe) fiber unit in the center and aluminum clad steel wire stranding process in the outer layer. The product is suitable for the operation of single tube optical fiber unit. -
Optic Fiber Terminal Box
Design of hinge and convenient press-pull button lock. -
J Clamp J-Hook Small Type Suspension Clamp
OYI anchoring suspension clamp J hook is durable and of good quality, making it a worthwhile choice. It plays an important role in many industrial settings. The main material of the OYI anchoring suspension clamp is carbon steel, and the surface is electro galvanized, allowing it to last for a long period without rusting as a pole accessory. The J hook suspension clamp can be used with the OYI series stainless steel bands and buckles to fix cables onto poles, playing different roles in different places. Different cable sizes are available. The OYI anchoring suspension clamp can be used to link signs and cable installations on posts. It is electro galvanized and can be used outside for more than 10 years without rusting. There are no sharp edges, and the corners are rounded. All items are clean, rust free, smooth, and uniform throughout, and free from burrs. It plays a huge role in industrial production. -
Direct Bury (DB) 7-way 7/3.5mm
A bundle of micro- or mini-tubes with strengthened wall thickness is encased in a single thin HDPE sheath, forming a duct assembly specifically engineered for fiber optical cable deployment. This robust design enables versatile installation—either retrofitted into existing ducts or directly buried underground—supporting seamless integration into fiber optical cable networks. The micro ducts are optimized for high-efficiency fiber optical cable blowing, featuring an ultra-smooth inner surface with low-friction properties to minimize resistance during air-assisted cable insertion. Each micro duct is color-coded per Figure 1, facilitating quick identification and routing of fiber optical cable types (e.g., single-mode, multi-mode) during network installation and maintenance.
