Grounding and Bonding of Optical Fiber Cable in Aerial Applications
The NESC recommends, in Section 9, that the messenger wire employed to support aerial optical fiber cables be grounded at four connections in each installed mile.

The NESC recommends, in Section 9, that the messenger wire employed to support aerial optical fiber cables be grounded at four connections in each installed mile. 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. This Applications Engineering Note (AE Note) discusses conventional bonding and grounding practices for conductive fiber optic cable and hardware installations within the scope of the National Electrical Code (NEC). 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.
