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.

OYI-FOSC-09H
The OYI-FOSC-09H 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 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.

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.

LGX Insert Cassette Type Splitter
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. It 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.
