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.

Non-metallic Central Tube Access Cable
The fibers and water-blocking tapes are positioned in a dry loose tube. The loose tube is wrapped with a layer of aramid yarns as a strength member. Two parallel fiber-reinforced plastics (FRP) are placed on the two sides, and the cable is completed with an outer LSZH sheath.

OYI-FOSC-D109H
The OYI-FOSC-D109H dome fiber optic splice closure is used in aerial, wall-mounting, and underground applications for the straight-through and branching splice of the fiber cable. Dome splicing closures are excellent protection of fiber optic joints from outdoor environments such as UV, water, and weather, with leak-proof sealing and IP68 protection.
The closure has 9 entrance ports on the end (8 round ports and 1 oval port). The shell of the product is made from PP+ABS material. The shell and the base are sealed by pressing the silicone rubber with the allocated clamp. The entry ports are sealed by heat-shrinkable tubes. The closures can be opened again after being sealed and reused without changing the sealing material.
The closure’s main construction includes the box, splicing, and it can be configured with adapters and optical splitters.

OYI-FOSC-D103H
The OYI-FOSC-D103H dome fiber optic splice closure is used in aerial, wall-mounting, and underground applications for the straight-through and branching splice of the fiber cable. Dome splicing closures are excellent protection of fiber optic joints from outdoor environments such as UV, water, and weather, with leak-proof sealing and IP68 protection.
The closure has 5 entrance ports on the end (4 round ports and 1 oval port). The shell of the product is made from ABS/PC+ABS material. The shell and the base are sealed by pressing the silicone rubber with the allocated clamp. The entry ports are sealed by heat-shrinkable tubes. The closures can be opened again after being sealed and reused without changing the sealing material.
The closure’s main construction includes the box, splicing, and it can be configured with adapters and optical splitters. -
Air Blowing Mini Optical Fibre Cable
The optical fiber is placed inside a loose tube made of high-modulus hydrolyzable material. The tube is then filled with thixotropic, water-repellent fiber paste to form a loose tube of optical fiber. A plurality of fiber optic loose tubes, arranged according to color order requirements and possibly including filler parts, are formed around the central non-metallic reinforcement core to create the cable core via SZ stranding. The gap in the cable core is filled with dry, water-retaining material to block water. A layer of polyethylene (PE) sheath is then extruded.
The optical cable is laid by air blowing microtube. First, the air blowing microtube is laid in the outer protection tube, and then the micro cable is laid in the intake air blowing microtube by air blowing. This laying method has a high fiber density, which greatly improves the utilization rate of the pipeline. It is also easy to expand the pipeline capacity and diverge the optical cable. -
