ADSS, OPGW and OPPC accessories are different types of fiber optic cables used to transmit electricity or communication signals. All Dielectric self-supporting (ADSS) does not need any metallic conductor for support. The optical fibers inside ADSS cables help in data communication. This includes telecommunication or internet services. They work with suspension clamps, tension clamps, vibration dampers and dead-ends. Optical Ground Wire (OPGW) acts as both ground wire for electrical protection and communication medium for data transmission. They work with accessories such as ground wire grips, optical fiber splice closures and preformed line products. Optical phase conductors (OPPC) integrate optical fibers into the conductive phase conductors themselves. It combines the functions of traditional conductors with communication capabilities. They work with accessories such as suspension clamps, dampers and spacers.
