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-FAT16F Series Terminal Box
The 16-core OYI-FAT16F optical terminal box performs in accordance with the industry standard requirements of YD/T2150-2010. It is mainly used in the FTTX (solutions) 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-FAT16F 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. There are 3 cable holes under the box that can accommodate 3 outdoor optical cables for direct or different junctions, and it can also accommodate 16 FTTH drop optical cables for end connections. The fiber splicing tray uses a flip form and can be configured with 16 cores capacity specifications to accommodate the box’s expansion needs. -
GYFJH
The GYFJH radio frequency remote fiber optic cable. The structure of the optical cable is using two or four single-mode or multi-mode fibers which directly covered with low-smoke and halogen-free material to make tight-buffer fiber, each cable uses high-strength aramid yarn as the reinforcing element, and is extruded with a layer of LSZH inner sheath. Meanwhile, in order to fully ensure the roundness and physical and mechanical characteristics of the cable, two aramid fiber filing ropes are placed as reinforcement elements, Sub cable and the filler unit are twisted to form a cable core and then extruded by LSZH outer sheath (TPU or other agreed sheath material is also available upon request). -
Direct Installation (DI) 24-way 8/5mm+1-way 10/...
A bundle of micro- or mini-tubes with strengthened wall thickness is encased in a single thin HDPE sheath, forming a duct assembly specifically engineered for fiber optical cable deployment. This robust design enables versatile installation—either retrofitted into existing ducts or directly buried underground—supporting seamless integration into fiber optical cable networks. The micro ducts are optimized for high-efficiency fiber optical cable blowing, featuring an ultra-smooth inner surface with low-friction properties to minimize resistance during air-assisted cable insertion. Each micro duct is color-coded per Figure 1, facilitating quick identification and routing of fiber optical cable types (e.g., single-mode, multi-mode) during network installation and maintenance. -

Module OYI-1L311xF
OYI-1L311xF Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA), The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the FP laser and the PIN photo-detector, the module data link up to 10km in 9/125um single mode fiber. The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also 02 can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.
