Product Detail


Product Tags

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.

    • Self-supporting  Figure 8  Fiber Optic Cable

      Self-supporting Figure 8 Fiber Optic Cable

      The 250um fibers are positioned in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire is located in the center of the core as a metallic strength member. The tubes (and fibers) are stranded around the strength member into a compact and circular cable core. After an Aluminum (or steel tape) Polyethylene Laminate (APL) moisture barrier is applied around the cable core, this part of the cable, accompanied by the stranded wires as the supporting part, is completed with a polyethylene (PE) sheath to form a figure 8 structure. Figure 8 cables, GYTC8A and GYTC8S, are also available upon request. This type of cable is specifically designed for self-supporting aerial installation.

    • Anchoring Clamp JBG Series

      Anchoring Clamp JBG Series

      JBG series dead end clamps are durable and useful. They are very easy to install and are specially designed for dead-ending cables, providing great support for the cables. The FTTH anchor clamp is designed to fit various ADSS cable and can hold cables with diameters of 8-16mm. With its high quality, the clamp plays a huge role in the industry. The anchor clamp’s main materials are aluminum and plastic, which are safe and environmentally friendly. The drop wire cable clamp has a nice appearance with a silver color and works great. It’s easy to open the bails and fix to the brackets or pigtails, making it very convenient to use without tools and saving time.

    • OYI-FOSC-H13


      The OYI-FOSC-05H 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 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.

    • Flat Twin Fiber Cable GJFJBV

      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)

    • ADSS Suspension Clamp Type A

      ADSS Suspension Clamp Type A

      The ADSS suspension unit is made of high tensile galvanized steel wire materials, which have higher corrosion resistance capability and can extend the lifetime usage. The gentle rubber clamp pieces improve self-damping and reduce abrasion.

    • Anchoring Clamp PA2000

      Anchoring Clamp PA2000

      The anchoring cable clamp is of high quality and durable. This product consists of two parts: a stainless steel wire and its main material, a reinforced nylon body that is lightweight and convenient to carry outdoors. The clamp’s body material is UV plastic, which is friendly and safe and can be used in tropical environments. The FTTH anchor clamp is designed to fit various ADSS cable designs and can hold cables with diameters of 11-15mm. It is used on dead-end fiber optic cables. Installing the FTTH drop cable fitting is easy, but preparation of the optical cable is required before attaching it. The open hook self-locking construction makes installation on fiber poles easier. The anchor FTTX optical fiber clamp and drop wire cable brackets are available either separately or together as an assembly.

      FTTX drop cable anchor clamps have passed tensile tests and have been tested in temperatures ranging from -40 to 60 degrees Celsius. They have also undergone temperature cycling tests, aging tests, and corrosion-resistant tests.
