  • The function of grounding the optical cable tip

    The function of grounding the optical cable tip

    Optical cable grounding is an important measure to protect optical cables and their connected equipment from lightning strikes, electrostatic discharge and electromagnetic interference. However, this does not mean every fiber optic installation is exempt from grounding requirements. The critical distinction lies in. An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. It is increasingly utilized in high-voltage transmission lines as a functional element that both safeguards the power system and allows data sharing across the grid.
