"Smart OPGW accessories" are at the forefront of grid modernization:

• Integrated Sensors: These accessories can incorporate micro-sensors for real-time monitoring of parameters like cable temperature, sag, vibration levels, and even ice loading.

• IoT Connectivity: Data from these sensors can be transmitted wirelessly (via cellular, satellite, or the OPGW's own fiber) to central control systems, leveraging the Internet of Things (IoT).

• Predictive Maintenance: By continuously analyzing this data, utilities can move from reactive to predictive maintenance, identifying potential issues (e.g., excessive vibration indicating damper failure, high temperature indicating overload) before they become critical.

• Enhanced Grid Awareness: Provides unprecedented insight into the real-time health and performance of the transmission line, improving reliability, optimizing power flow, and facilitating quicker fault location.

These accessories are transforming OPGW from just a ground wire into an intelligent data backbone for the power grid.
