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-FAT08D Terminal Box
The 8-core OYI-FAT08D optical terminal box performs in accordance with the industry standard requirements of YD/T2150-2010. It is mainly used in the FTTX access system terminal link. The box is made of high-strength PC, ABS plastic alloy injection molding, which provides good sealing and aging resistance. In addition, it can be hung on the wall outdoors or indoors for installation and use. The OYI-FAT08D optical terminal box has an inner design with a single-layer structure, divided into the distribution line area, outdoor cable insertion, fiber splicing tray, and FTTH drop optical cable storage. The fiber optical lines are very clear, making it convenient to operate and maintain. It can accommodate 8 FTTH drop optical cables for end connections. The fiber splicing tray uses a flip form and can be configured with 8 cores capacity specifications to meet the expansion needs of the box.

SFP-ETRx-4
The ER4 is a transceiver module designed for 40km optical communication applications. The design is compliant to 40GBASE-ER4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically demultiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data.

OYI-OCC-E Type
Fiber optic distribution terminal is the equipment used as a connection device in the fiber optic access network for feeder cable and distribution cable. Fiber optic cables are spliced directly or terminated and managed by patch cords for distribution. With the development of FTTX, outdoor cable cross-connection cabinets will be widely deployed and move closer to the end user.

Duplex Patch Cord
OYI fiber optic duplex patch cord, also known as a fiber optic jumper, is composed of a fiber optic cable terminated with different connectors on 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 patch cables, connectors such as SC, ST, FC, LC, MU, MTRJ, DIN and E2000 (APC/UPC polish) are available. Additionally, we also offer MTP/MPO patch cords.

Armored Optic Cable GYFXTS
Optical fibers are housed in a loose tube that is made of high-modulus plastic and filled with water blocking yarns. A layer of non-metallic strength member is stranding around the tube, and the tube is armored with the plastic coated steel tape. Then a layer of PE outer sheath is extruded.

Bundle Tube Type all Dielectric ASU Self-Suppor...
The structure of the optical cable is designed to connect 250 μm optical fibers. The fibers are inserted into a loose tube made of high modulus material, which is then filled with waterproof compound. The loose tube and FRP are twisted together using SZ. Water blocking yarn is added to the cable core to prevent water seepage, and then a polyethylene (PE) sheath is extruded to form the cable. A stripping rope can be used to tear open the optical cable sheath.
