OPGW Optical Ground Wire
OPGW Optical Ground Wire
Stranded Unit Type in The Eccentric Inner Layer 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 multiple sub-units 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.

Flat Twin Fiber Cable GJFJBV
The flat twin cable uses 600μm or 900μm tight buffered fiber as the optical communication medium. The tight buffered fiber is wrapped with a layer of aramid yarn as a strength member. Such a unit is extruded with a layer as an inner sheath. The cable is completed with an outer sheath.(PVC, OFNP, or LSZH)

OYI-FOSC HO7
The OYI-FOSC-02H horizontal fiber optic splice closure has two connection options: direct connection and splitting connection. It is applicable in situations such as overhead, man-well of pipeline, and embedded situations, among others. Comparing with a terminal box, the closure requires much stricter sealing requirements. Optical splice closures are used to distribute, splice, and store outdoor optical cables that enter and exit from the ends of the closure.
The closure has 2 entrance ports. The shell of the product is made from ABS+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.

Loose Tube Corrugated Steel/Aluminum Tape Flame...
The fibers are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound, and a steel wire or FRP is located in the center of the core as a metallic strength member. The tubes (and the fillers) are stranded around the strength member into a compact and circular core. The PSP is longitudinally applied over the cable core, which is filled with filling compound to protect it from water ingress. Finally, the cable is completed with a PE (LSZH) sheath to provide additional protection.

OYI-ATB08B Terminal Box
OYI-ATB08B 8-Cores Terminal box is developed and produced by the company itself. The product’s performance meets the requirements of industry standards YD/T2150-2010. It is suitable for installing multiple types of modules and can be applied to the work area wiring subsystem to achieve dual-core fiber access and port output. It provides fiber fixing, stripping, splicing, and protection devices, and allows for a small amount of redundant fiber inventory, making it suitable for FTTH (FTTH drop optical cables for end connections) system applications. The box is made of high-quality ABS plastic through injection molding, making it anti-collision, flame retardant, and highly impact-resistant. It has good sealing and anti-aging properties, protecting the cable exit and serving as a screen. It can be installed on the wall.
