Optical Ground Wire (OPGW)

Optical Ground Wire (OPGW)

Downloding OPGW spicificattion Catalog

An overhead ground wire is installed to protect phase conductors from lightning and reduce electromagnetic interference against telecommunication lines during the grounding of power lines.

An optical fiber can transmit a large amount of information in high speeds and suffers no electromagnetic interference because of its non-metallic characteristics. This advantageous feature makes it possible to construct long distance telecommunication lines with high reliablity.

Generally, OPGW has dual performance functions of conventional ground wire with optical fiber telecommunication capabilities.

Typical Construction of an OPGW cable:

1. The Optical Fibers
2. The Stainless Steel central buffer tube.
3. The Cable Armoring consisting of one, two or more layers of armoring wires.

Features & Benefits

Our high quality standards for designing, testing and manufacturing with the highest grade materials available to ensure long-term reliability.

Maximum fiber counts up to 72 fibers with minimized cable diameter due to variable designs.

Superior optical performance over a broad temperature range

from -40 C to +85 C

Engineering support, supervising and providing its own line of accessory hardware.

Excellent tensile performance under cable elongation and contraction due to extreme tension and variation of temperature.

Moisture-proof jelly filled core for superior protection to the optical fibers due to hydrogen generation in metal structure.

Continuous and seamless tube for superior protection to the optical fibers from moisture and extreme environmental conditions such as lateral force.
