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.

OYI-FOSC-H06
The OYI-FOSC-01H 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, embedded situation, etc. Comparing with a terminal box, the closure requires much stricter requirements of seal. Optical splice closures are used to distribute, splice, and store the outdoor optical cables which 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.

OYI J Type Fast Connector
Our fiber optic fast connector, the OYI J type, is designed for FTTH (Fiber to The Home), FTTX (Fiber To The X). It is a new generation of fiber connector used in assembly that provides open flow and precast types, meeting the optical and mechanical specifications of standard optical fiber connectors. It is designed for high quality and high efficiency during installation.
Mechanical connectors make fiber terminations quick, easy, and reliable. These fiber optic connectors offer terminations without any hassle and require no epoxy, no polishing, no splicing, and no heating, achieving similar excellent transmission parameters as standard polishing and splicing technology. Our connector can greatly reduce the assembly and setup time. The pre-polished connectors are mainly applied to FTTH cables in FTTH projects, directly at the end-user site. -
Simplex Patch Cord
OYI fiber optic simplex patch cord, also known as a fiber optic jumper, is composed of a fiber optic cable terminated with different connectors at each end. Fiber optic patch cables are used in two major application areas: connecting 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 of the patch cables, connectors such as SC, ST, FC, LC, MU, MTRJ, and E2000 (with APC/UPC polish) are available. Additionally, we also offer MTP/MPO patch cords.

Multi-Purpose Distribution cable GJFJV(H)
GJFJV is a multi-purpose distribution cable that uses several φ900μm flame-retardant tight buffer fibers as optical communication medium. The tight buffer fibers are wrapped with a layer of aramid yarn as strength member units, and the cable is completed with a PVC, OPNP, or LSZH (Low smoke, Zero halogen, Flame-retardant) jacket.
