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.

Direct Bury (DB) 7-way 7/4mm
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, facilitating quick identification and routing of fiber optical cable types (e.g., single-mode, multi-mode) during network installation and maintenance. As a leading provider of such specialized fiber optic infrastructure solutions, Oyi International., Ltd.—a dynamic, innovation-driven firm headquartered in Shenzhen, China—has been delivering world-class products and end-to-end services since 2006. Backed by a 20+ member R&D team, the company serves 143 countries through long-term partnerships with 268 global clients, offering a comprehensive portfolio including optical fiber cables, integrated solutions like FTTH and ONUs, as well as tailored OEM design and financial support to help customers optimize costs and platform integration. -
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. -
Fanout Multi-core (4~48F) 2.0mm Connectors Patc...
OYI fiber optic fanout patch cord, also known as a fiber optic jumper, is composed of a fiber optic cable terminated with different connectors on each end. Fiber optic patch cables are used in two major application areas: computer workstations to outlets and patch panels or optical cross-connect distribution centers. OYI provides various types of fiber optic patch cables, including single-mode, multi-mode, multi-core, armored patch cables, as well as fiber optic pigtails and other special patch cables. For most patch cables, connectors such as SC, ST, FC, LC, MU, MTRJ, and E2000 (APC/UPC polish) are all available. -
Bare Fiber Type Splitter
A fiber optic PLC splitter, also known as a beam splitter, is an integrated waveguide optical power distribution device based on a quartz substrate. It is similar to a coaxial cable transmission system. The optical network system also requires an optical signal to be coupled to the branch distribution. The fiber optic splitter is one of the most important passive devices in the optical fiber link. It is an optical fiber tandem device with many input terminals and many output terminals, and is especially applicable to a passive optical network (EPON, GPON, BPON, FTTX, FTTH, etc.) to connect the ODF and the terminal equipment and to achieve the branching of the optical signal. -
Wire Rope Thimbles
Thimble is a tool that is made to maintain the shape of a wire rope sling eye in order to keep it safe from various pulling, friction, and pounding. Additionally, this thimble also has the function of protecting the wire rope sling from being crushed and eroded, allowing the wire rope to last longer and be used more frequently. Thimbles have two main uses in our daily lives. One is for wire rope, and the other is for guy grip. They are called wire rope thimbles and guy thimbles. Below is a picture showing the application of wire rope rigging. -
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.
