An Optical Ground Wire (OPGW) is a type of overhead shield wire that contains optical fibers. These optical fibers are enclosed within aluminium or stainless-steel tubes, with a specific number of fibers per tube. The design of the conductor may also incorporate various layers of aluminium-clad steel strands (AW), aluminium strands, aluminium-alloy strands, or a combination of these, based on their electrical and mechanical properties. By combining different types of aluminium, aluminium-clad steel, and aluminium-alloy strands, the OPGW can be tailored to achieve specific electrical and mechanical characteristics as required by the customer.

An Optical Ground Wire (OPGW) is a type of overhead shield wire that contains optical fibers. These optical fibers are enclosed within aluminium or stainless-steel tubes, with a specific number of fibers per tube. The design of the conductor may also incorporate various layers of aluminium-clad steel strands (AW), aluminium strands, aluminium-alloy strands, or a combination of these, based on their electrical and mechanical properties. By combining different types of aluminium, aluminium-clad steel, and aluminium-alloy strands, the OPGW can be tailored to achieve specific electrical and mechanical characteristics as required by the customer. The primary purpose of the OPGW is twofold. Firstly, it is employed at the top of transmission line towers to safeguard the phase wire against sudden currents caused by lightning strikes. These transient currents are directed to the ground through the earth wire. Secondly, the OPGW serves as a medium for transmitting video and audio data through its optical fibers. The number of optical fibers contained within the tube can vary depending on the customer's requirements, ranging from 12, 24, 36, 48 to even more fibers. During the production and design of OPGW, either Single-Mode or Multi-Mode fibers can be utilized. Single-Mode fibers are suitable for longer distances exceeding 1 km, offering high bandwidth, while Multi-Mode fibers are used for shorter distances under 1 km, providing lower bandwidth capabilities.
There are two primary categories of Single-Mode optical fibers: SMF (Single-Mode Fiber) and NZDSF (Non-Zero Dispersion Shifted Fibers). SMF, an earlier iteration, is most effective within the wavelength range of 1310 and 1550 nm. This particular fiber type exhibits reduced dispersion at the 1310 nm wavelength, making it suitable for applications involving long distances, urban environments, CATV (Cable Television), intelligent traffic control, and communications. On the other hand, NZDSF represents a more advanced iteration and is tailored for DWDM (Dense Wavelength Division Multiplexing). This newer generation demonstrates significantly decreased dispersion within the wavelength range of 1530 to 1625 nm, in contrast to SMF.
