OPGW Optical Ground Wire
OPGW Optical Ground Wire
Central Optical Unit Type Optical Unit In The Center Of Cable
Optical ground wire (OPGW) is a dual functioning cable. It is designed to replace traditional static/shield/earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes. OPGW must be capable of withstanding the mechanical stresses applied to overhead cables by environmental factors such as wind and ice. OPGW must also be capable of handling electrical faults on the transmission line by providing a path to ground without damaging the sensitive optical fibers inside the cable.
The OPGW cable design is constructed of a fiber optic core (with single tube optical fiber unit depending on the fiber count) encased in a hermetically sealed hardened aluminum pipe with a covering of one or more layers of steel and/or alloy wires. Installation is very similar to the process used to install conductors, although care must be taken to use the proper sheave or pulley sizes so as not to cause damage or crush the cable. After installation, when the cable is ready to be spliced, the wires are cut away exposing the central aluminum pipe which can easily be ring-cut with a pipe cutting tool. The color-coded sub-units are preferred by most users because they make splice box preparation very simple.

OYI-FAT48A Terminal Box
The 48-core OYI-FAT48A series optical terminal box performs in accordance with the industry standard requirements of YD/T2150-2010. It is mainly used in the FTTX access system terminal link. The box is made of high-strength PC, ABS plastic alloy injection molding, which provides good sealing and aging resistance. In addition, it can be hung on the wall outdoors or indoors for installation and use.
The OYI-FAT48A optical terminal box has an inner design with a single-layer structure, divided into the distribution line area, outdoor cable insertion, fiber splicing tray, and FTTH drop optical cable storage area. The fiber optical lines are very clear, making it convenient to operate and maintain. There are 3 cable holes under the box that can accommodate 3 outdoor optical cables for direct or different junctions, and it can also accommodate 8 FTTH drop optical cables for end connections. The fiber splicing tray uses a flip form and can be configured with 48 cores capacity specifications to meet the expansion needs of the box.

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.

OYI-FOSC H12
The OYI-FOSC-04H 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 2 entrance ports and 2 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.
