OPGW Cable
OPGW (Optical Ground Wire) cable is used in power transmission lines for both protection against lightning and data transmission, meeting the demand for high-capacity communication.Furukawa Electric, manufactures OPGW cable in Brazil and resells fixing hardware and accessories. Installation design, supervision services, training, splicing and field-testing are also in Furukawa's scope of supply. All this guarantees electrical, mechanical and optical characteristics of the cable and its components.
