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.

Multi Purpose Distribution Cable GJPFJV(GJPFJH )
The multi-purpose optical level for wiring uses subunits, which consist of medium 900μm tight sleeved optical fibers and aramid yarn as reinforcement elements. The photon unit is layered on the non-metallic center reinforcement core to form the cable core, and the outermost layer is covered with a low smoke, halogen-free material (LSZH) sheath that is flame retardant.(PVC)

Loose Tube Non-metallic Heavy Type Rodent Prote...
Insert the optical fiber into the PBT loose tube, fill the loose tube with waterproof ointment. The center of the cable core is a non-metallic reinforced core, and the gap is filled with waterproof ointment. The loose tube (and filler) is twisted around the center to strengthen the core, forming a compact and circular cable core. A layer of protective material is extruded outside the cable core, and glass yarn is placed outside the protective tube as a rodent proof material. Then, a layer of polyethylene (PE) protective material is extruded.(WITH DOUBLE SHEATHS)

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-FOSC-09H
The OYI-FOSC-09H 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 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.

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.

OYI-ODF-FR-Series Type
The OYI-ODF-FR-Series type optical fiber cable terminal panel is used for cable terminal connection and can also be used as a distribution box. It has a 19″ standard structure and is of the fixed rack-mounted type, making it convenient to operate. It is suitable for SC, LC, ST, FC, E2000 adapters, and more.
The rack mounted optical cable terminal box is a device that terminates between the optical cables and the optical communication equipment. It has the functions of splicing, termination, storing, and patching of optical cables. The FR-series rack mount fiber enclosure provides easy access to fiber management and splicing. It offers a versatile solution in multiple sizes (1U/2U/3U/4U) and styles for building backbones, data centers, and enterprise applications.
