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.

Loose Tube Armored Flame-retardant Direct Burie...
The fibers are positioned in a loose tube made of PBT. The tubes are filled with a water-resistant filling compound. 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. An Aluminum Polyethylene Laminate (APL) or steel tape is applied around the cable core, which is filled with filling compound to protect it from water ingress. Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE (LSZH) outer sheath.(WITH DOUBLE SHEATHS)

OYI-FOSC-H06
The OYI-FOSC-01H horizontal fiber optic splice closure has two connection ways: direct connection and splitting connection. They are applicable to situations such as overhead, man-well of pipeline, embedded situation, etc. Comparing with a terminal box, the closure requires much stricter requirements of seal. Optical splice closures are used to distribute, splice, and store the outdoor optical cables which 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.

OYI-ODF-R-Series Type
The OYI-ODF-R-Series type series is a necessary part of the indoor optical distribution frame, specially designed for optical fiber communication equipment rooms. It has the function of cable fixation and protection, fiber cable termination, wiring distribution, and protection of fiber cores and pigtails. The unit box has a metal plate structure with a box design, providing a beautiful appearance. It is designed for 19″ standard installation, offering good versatility. The unit box has a complete modular design and front operation. It integrates fiber splicing, wiring, and distribution into one. Each individual splice tray can be pulled out separately, enabling operations inside or outside the box.
The 12-core fusion splicing and distribution module plays the main role, with its function being splicing, fiber storage, and protection. A completed ODF unit will include adapters, pigtails, and accessories such as splice protection sleeves, nylon ties, snake-like tubes, and screws.
