Description
OPGW fiber optic cable is a dual functioning cable performing the duties of a ground wire and also providing a patch for the transmission of voice, video or data signals. The cable is designed to be installed on transmission and distribution lines. The fibers are protected from environmental conditions (lightning, short circuit, loading) to ensure the reliability of signal transmission.
