OPGW cable
The OPGW cable (Optical Ground Wire) is a specialized type of optical fiber cable used in the airlines of electricity transport.
It is designed to provide a redundant communication path for the transmission line, as well as to ensure protection against lightning and other electric disturbances.
OPGW fibers provide a redundant communication route and protection against electric disturbances, while the ACSR drivers transport electrical energy.
Description The ZMS OPGW
OPGW air fiber cable from the manufacturer of ZMS optical fiber cables is placed in the soil of high voltage transmission lines to form an optical fiber communication network on the transmission line.
This structure has the dual land and communication line function.
The winding of the metal wire makes the earth cable with fiber optic more reliable, more stable and more solid.
Like the aerial earth cable and the optical fiber cable are combined in a whole, This shortens the construction cycle and reduces construction costs compared to other optical fiber cable methods.
OPGW – Monomode
OPGW cable are less affected by the modal dispersion, This means that the signal is less affected by the multiple paths of light in the heart of the fiber, which allows the signal to travel further and maintain its integrity over a longer distance.
Structure：The OPGW monomode cable is designed to allow light transmission over long distances with minimum attenuation, This thanks to the use of a smaller core diameter of the optical fibers, generally around 8-10 microns.
Application : The OPGW Monomodes cable are generally used in applications that require large -band communications over long distances, Like long -distance telecommunications and high speed internet.

OPGW – Multimode
The greater size of their hearts, Multimod fibers are less affected by the precise alignment of the optical source and the receiver and they tend to be less expensive than the monomod fibers, But they are more affected by the modal dispersion, This means that the signal is distributed over several light paths in the heart of the fiber, which can lead to a signal loss and a distortion over long distances.
Application : OPGW Multimod cables are generally used in applications that require low -band communications over short distances, like short distance telecommunications, Industrial networks and internal networks. They can also be used in public electricity services and other industries that require reliable and lower speed communications.

Difference between OPGW and adss cables
OPGW cables (Optical Ground Wire) et ADSS (All-Dielectric Self-Supporting) are two types of optical fiber cables used in the airlines of electricity transport, But they are different in their design and application.
The main difference between the two lies in the materials used and the way they are supported. OPGW cables are generally made of aluminum steel, with a central tube filled with optical fibers, Surrounded by a layer of steel wires dressed in aluminum. These cables are used to ensure both earth and communication in electricity transport lines, where they are suspended from the existing suspension clips of the power line.
On the other hand, ADSS cables are entirely made of glass or plastic and are self -supporting, This means that they do not need external supports such as metal messengers or conductive supports. They are generally fixed directly to the pylons of the electric lines, Using specialized equipment. ADSS cables are used in energy and communication distribution networks, where self -supporting and the absence of metal components make it possible not to interact with electricity.
Another major difference is that the OPGW cable is designed to act as a grounding thread as well as to provide a communication path, While the ADSS cable is intended for communication only. Furthermore, OPGW cables are generally more expensive than adss, partly because of the cost of steel components covered with aluminum.
