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.

All Dielectric Self-Supporting Cable
The structure of ADSS (single-sheath stranded type) is to place 250um optical fiber into a loose tube made of PBT, which is then filled with waterproof compound. The center of the cable core is a non-metallic central reinforcement made of fiber-reinforced composite (FRP). The loose tubes (and filler rope) are twisted around the central reinforcing core. The seam barrier in the relay core is filled with water-blocking filler, and a layer of waterproof tape is extruded outside the cable core. Rayon yarn is then used, followed by extruded polyethylene (PE) sheath into the cable. It is covered with a thin polyethylene (PE) inner sheath. After a stranded layer of aramid yarns is applied over the inner sheath as a strength member, the cable is completed with a PE or AT (anti-tracking) outer sheath.

Anchoring Clamp PA300
The anchoring cable clamp is a high-quality and durable product. It consists of two parts: a stainless-steel wire and a reinforced nylon body made of plastic. The body of the clamp is made of UV plastic, which is friendly and safe to use even in tropical environments. The FTTH anchor clamp is designed to fit various ADSS cable designs and can hold cables with diameters of 4-7mm. 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. They have also undergone temperature cycling tests, aging tests, and corrosion-resistant tests.

OYI-FOSC H10
The OYI-FOSC-03H 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, 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+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-F234-8Core
This box is used as a termination point for the feeder cable to connect with drop cable in FTTX communication network system. It integrates fiber splicing, splitting, distribution, storage and cable connection in one unit. Meanwhile, it provides solid protection and management for the FTTX network building.

SC/APC SM 0.9MM 12F
Fiber optic fanout pigtails provide a swift method for creating communication devices in the field. They are designed, manufactured, and tested according to protocols and performance standards set by the industry, meeting your most stringent mechanical and performance specifications.
The fiber optic fanout pigtail is a length of fiber cable with a multi-core connector fixed on one end. It can be divided into single mode and multi mode fiber optic pigtail based on the transmission medium; it can be divided into FC, SC, ST, MU, MTRJ, D4, E2000, LC, etc., based on the connector structure type; and it can be divided into PC, UPC, and APC based on the polished ceramic end-face.
Oyi can provide all kinds of optic fiber pigtail products; the transmission mode, optical cable type, and connector type can be customized as needed. It offers stable transmission, high reliability, and customization, making it widely used in optical network scenarios such as central offices, FTTX, and LAN, etc.
